# Support code to run on EV3 brick
## Kernel module
Kernel module is based on LEGO's `d_usbdev` module, with the addition of slightly modified `g_mass_storage`
module from the Linux kernel. The module and supporting sources are licensed under GPLv2 (since
they are derived from GPLv2 code).
### Modifications
* the `d_usbdev` uses the composite framework to register an additional mass storage function in addtion
to the pre-existing custom USB HID function
* the `g_mass_storage` module has the following changes:
* a bug fixed, where page-misaligned writes would hang
* additional `/sys/.../lun0/active` entry is added, which allows for signaling drive eject to the host
### Kernel modifications
The kernel itself has modified FIFO queue sizes. The LEGO kernel uses `1024` for `ep1in` and `ep1out`,
and then `64` for `ep2` and `ep3`. Note that this is non-standard modification done with a kernel patch,
that I didn't manage to find. The MSD requires `512` for `ep2` and `ep3`. I have binary edited the kernel
to do so.
Note that there's 4k of FIFO memory in the hardware. If you set the queue sizes with a sum of more than
4k, the kernel will hang, and you will not know why.
## UF2 Daemon
The [UF2](https://github.com/Microsoft/uf2) daemon is based on
[UF2 ATSAMD21](https://github.com/Microsoft/uf2-samd21) bootloader code. It exposes a virtual
FAT16 file system over Linux Network Block Device interface (`/dev/nbd0` to be precise).
This device is then exposed via the `g_mass_storage` module to the host computer.
The Daemon is licensed under MIT.

* USB device controllers have lots of quirks. Use these macros in
* gadget drivers or other code that needs to deal with them, and which
* autoconfigures instead of using early binding to the hardware.
*
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
* some config file that gets updated as new hardware is supported.
* (And avoiding all runtime comparisons in typical one-choice configs!)
*
* NOTE: some of these controller drivers may not be available yet.
* Some are available on 2.4 kernels; several are available, but not
* yet pushed in the 2.6 mainline tree.

* The image consists of three different components in this fixed order: imageheader, objectheaders and byte codes.

* The imageheader tells something about image version, filesize, no of objectheaders (objects) and no of global variable bytes.
*
*
* Objectheaders contains different informations depending on the nature of the object:
*
*- The VMTHREAD object (former TBC_TOPVI) \n
* - OffsetToInstructions tells were to find the corresponding byte codes (offset from image start) \n
* - OwnerObjectId must be zero \n
* - TriggerCount is used but must be zero \n
* - LocalBytes describes the number of bytes for local variables \n
*
*- The SUBCALL object (former TBC_VI and TBC_VI_ALIAS) \n
* - OffsetToInstructions tells were to find the corresponding byte codes (if alias this is equal to mother object) \n
* - OwnerObjectId must be zero \n
* - TriggerCount is used and must be one \n
* - LocalBytes describes the number of bytes for local variables \n
*
*- The BLOCK object (former CLUMP) \n
* - OffsetToInstructions tells were to find the corresponding byte codes (offset from image start) \n
* - OwnerObjectId is equal to object id it belongs to (not equal to zero) \n
* - TriggerCount is used to determine how many triggers needed before the BLOCK object is activated \n
* - LocalBytes must be zero (locals are defined in the owner object) \n
*
* Byte codes are described in a different section.
*
* Little Endian are used (addresses and data are represented with LSB on lowest address and MSB on highest address).
*
* Offset to instructions is number of bytes from start of image to start of object instructions.
*
* Index to global variables are byte based and counted from start of globals (zero based).
*
* Index to local variables are byte based and counted from start of object locals (zero based).
*
* Object ID's is not zero based - First object (VMTHEAD) is named 1.

## [Compile and Flash: Your Program!](/device/usb)
#### Using LEGO® MINDSTORMS® Education NXT
The MakeCode editor works with @boardname@. To create code for LEGO® MINDSTORMS® Education NXT, you need to [download](https://education.lego.com/downloads/retiredproducts/nxt/software) the software to program it.
### ~
## Compile and Flash: Your Program!
When you have your code ready, you connect your EV3 Brick to a computer with a USB cable so it appears as an attached drive (named **@drivename@**).
When you have your code ready, you connect your @boardname@ to a computer via a USB cable
**then press the reset button** so it appears as a mounted drive (named **CPLAYBOOT**).
Compilation to machine code from [Blocks](/blocks) or [JavaScript](/javascript) happens in the browser. You save the binary
program to a **.uf2** file, which you then copy to the **@drivename@** drive. The process of copying will flash the device with the new program.
### ~ hint
#### Bluetooth support
**Experimental support** for Bluetooth download is now available. Please read the [Bluetooth](/bluetooth) page for more information.
### ~
program to a **.uf2** file, which you then copy to the **CPLAYBOOT** drive, which flashes the device with the new program.
## Simulator: Test Your Code
You can run your code using the @boardname@ simulator, all inside the same browser window.
The simulator has support for the EV3 Brick screen, buttons, sensors, and motors.
You can run your code using the micro:bit simulator, all within the confines of a web browser.
The simulator has support for the LED screen, buttons, as well as compass, accelerometer, and digital I/O pins.

# Bluetooth
This page describes the procedure to download MakeCode program to the EV3 brick
over Bluetooth.
## ~ hint
### WARNING: EXPERIMENTAL FEATURES AHEAD!
Support for Bluetooth download relies on [Web Serial](https://wicg.github.io/serial/),
an experimental browser feature. Web Serial is a work [in progress](https://www.chromestatus.com/feature/6577673212002304);
it may change or be removed in future versions without notice.
By enabling these experimental browser features, you could lose browser data or compromise your device security
or privacy.
## ~
https://youtu.be/VIq8-6Egtqs
## Supported browsers
* Chrome desktop, version 77 and higher, Windows 10 or Mac OS.
* [Microsoft Edge Insider desktop](https://www.microsoftedgeinsider.com), version 77 and higher, Windows 10 or Mac OS.
To make sure your browser is up to date, go to the '...' menu, click "Help" then "About".
Next you need to enable the experimental features (this may change in the future)
* go to **chrome://flags/#enable-experimental-web-platform-features** and **enable**
**Experimental Web Platform features**
![A screenshot of the flags page in chrome](/static/bluetooth/experimental.png)
## Machine Setup
* pair your EV3 brick with your computer over Bluetooth. This is the usual pairing procedure.
## Download over Bluetooth
* go to https://makecode.mindstorms.com/
* click on **Download** to start a file download as usual
* on the download dialog, you should see a **Bluetooth** button. Click on the
**Bluetooth** button to enable the mode.
* **make sure the EV3 brick is not running a program**
* click on **Download** again to download over bluetooth.
## Choosing the correct serial port
Unfortunately, the browser dialog does not make it easy to select which serial port is the brick.
* On Windows, choose ``Standard Serial over Bluetooth``. There might be multiple of those but only one works. Try your luck! Once you know the COM port number, remember it for the next time around.
* On Mac OS, choose ``cu.BRICKNAME-SerialPort``
## Known issues
* We do not detect properly that the program is running on the brick. Make sure to stop the program before starting the download procedure.
* The list of programs on the brick screen is not updated when uploading via bluetooth.
## Feedback
Please send us your feedback through https://forum.makecode.com.

# Autonomous Parking
Design cars that can park themselves safely without driver intervention.
![Autonomous parking graphic](/static/coding/autonomous-parking/auto-parking-connect.jpg)
## Connect
**Think about:**
* How do autonomous cars work?
* What would it take to ensure that autonomous cars are safe?
* What types of movements do autonomous cars need to perform?
## Construct
### Build
Build a @boardname@ vehicle that can park itself safely without driver intervention. Start by constructing this model:
[![EV3- Robot Driving Base](/static/coding/autonomous-parking/ev3-robot-driving-base.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf)
### ~hint
If clicking the above image doesn't open the instructions, right-click on the image and choose "Save link as..." to download the PDF.
### ~
### Check
Before you program, check:
* Are all the wires correctly connected from the motors to ports B and C?
* Are the wheels correctly installed?
* Are the wheels rotating freely?
### Program
Write a program that will make the robot turn three times in various ways.
**Think about:**
* How will you make the robot turn in different ways?
* How can the robot make a three point turn?
### ~hint
Consider using these blocks in your solution:
```block
motors.largeBC.tank(50, 50)
pause(500)
```
### ~
### Sample Solution - Three Point Turn
1. When the brick button is pressed, turn the driving base right and stop after 1.5 seconds.
2. Turn the driving base left and stop after 1 second.
3. Move the driving base forward for 3 seconds.
```blocks
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
motors.largeBC.tank(75, 30)
loops.pause(1500)
motors.largeBC.tank(-30, -75)
loops.pause(1000)
motors.largeBC.tank(50, 50)
loops.pause(3000)
})
```
### Download and test
Click Download and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
## Contemplate
Choose one of the following autonomous driving scenarios and create a program for it:
* Parallel parking
* Angle parking
* Perpendicular parking
### ~hint
Document pseudocode for your program before choosing programming blocks.
### ~

# Cruise Control
Learn how to set and adjust motor speeds.
## Activity 1
Increase motor speed when touch sensor `1` is pressed.
```blocks
let speed = 0;
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
if (speed < 100)
speed = speed + 10;
motors.largeBC.run(speed);
})
```
## Activity 2
Add a "reduce" motor speed action when touch sensor `2` is pressed.
```blocks
let speed = 0;
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
if (speed < 100)
speed = speed + 10;
motors.largeBC.run(speed);
})
sensors.touch2.onEvent(ButtonEvent.Pressed, function () {
if (speed > -100)
speed = speed - 10;
motors.largeBC.run(speed);
})
```
## Activity 3
Refactor your code by moving the speed increase and speed decrease code into ``||functions:accelerate||`` and ``||functions:decelerate||`` functions. Run the motors at the new speed in an ``||functions:update||`` function.
```blocks
let speed = 0
function decelerate() {
if (speed > -100) {
speed = speed - 10
}
}
function accelerate() {
if (speed < 100) {
speed = speed + 10
}
}
function update() {
brick.clearScreen()
brick.showString("speed: " + speed, 1)
motors.largeBC.run(speed)
}
sensors.touch2.onEvent(ButtonEvent.Pressed, function () {
accelerate()
update()
})
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
decelerate()
update()
})

# Line Detection
Design ways to improve driving safety by helping to prevent drivers from falling asleep and causing an accident.
![Car following the line on the road](/static/coding/line-detection/car-road-line.jpg)
## Connect
Think about:
* How can autonomous cars react to different traffic light signals?
* What can happen if a driver falls asleep while driving?
* How can we detect when a driver is falling asleep?
## Construct
### Build
Build a @boardname@ vehicle that can help prevent drivers from falling asleep and causing an accident. Start by constructing this model:
[![EV3 robot with color sensor](/static/coding/line-detection/ev3-robot-color-sensor-down.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-color-sensor-down-driving-base-d30ed30610c3d6647d56e17bc64cf6e2.pdf)
Build red and green “lights” for your robot to detect. You can use LEGO bricks, colored tape, or marker on white paper. Building instructions:
[![IMAGE: Color Squares](/static/coding/line-detection/ev3-color-squares.jpg)](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/color%20squares-0a88dfd98bb2e64b5b8151fc422bae36.pdf)
### ~hint
If clicking the above images doesn't open the instructions, right-click on the image and choose "Save link as..." to download the PDF.
### ~
### Check
Before you program, check:
* Are all the wires correctly connected from the motors to ports B and C?
* Are the wheels correctly installed?
* Are the wheels rotating freely?
* Are the wires connected from the Color Sensor to port 3?
![EV3 Driving Base](/static/coding/line-detection/ev3-robot-driving-base.jpg)
### Program
Autonomous cars need to recognize and respond to traffic lights automatically. Create a program that will make your robot stop at red lights. Make sure your robot is only responding to the color red. Once you have succeeded, program your robot to drive forward again when the light changes from red to green.
Before you program, think about:
* How will you program the robot to detect a color?
* How will you program the robot to stop at a color?
* Which programming blocks will you use?
### ~ hint
Consider using these blocks in your solution:
```block
loops.forever(function () {
})
motors.largeBC.steer(0, 50)
sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
motors.stopAll()
```
### ~
### Sample Solution - Red light detection
1. Loop forever.
2. Start motors ``B`` and ``C`` (drive forward).
3. Wait for the color sensor to detect the color red.
4. Stop all motors.
```blocks
loops.forever(function () {
motors.largeBC.steer(0, 50)
sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
motors.stopAll()
})
```
### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick.
Congratulations! Your robot can stop at a red light.
Now add to your program and have your robot to drive forward again when the light changes from red to green.
### Sample Solution - Red and green light detection in a loop
1. Start motors ``B`` and ``C`` (drive forward).
2. Wait for the color sensor to detect the color red.
3. Stop all motors.
4. Wait for the color sensor to detect the color green.
5. Loop forever.
```blocks
loops.forever(function () {
motors.largeBC.steer(0, 50)
sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
motors.stopAll()
sensors.color3.pauseUntilColorDetected(ColorSensorColor.Green)
})
```
### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick.
## Contemplate
To simulate what could happen if a driver falls asleep while driving, your robot could sound an alarm signal when it crosses the line. This feature is often available in new cars.
Program your robot to perform this function.
Draw a dark line with tape or marker for your robot to cross.
### ~hint
Consider using these blocks in your solution:
```block
motors.largeBC.steer(0, 50)
music.playSoundEffect(sounds.systemGeneralAlert)
```
### ~
### Sample Solution - Line detection in a loop
1. Start motors ``B`` and ``C`` (drive forward with a curve toward the line).
2. Wait for the color sensor to detect the color black.
3. Play sound effect ``system general alert``.
4. Start motors ``B`` and ``C`` (drive forward with a curve away from the line).
5. Wait for the color sensor to detect the color white.
6. Loop forever.
```blocks
loops.forever(function () {
motors.largeBC.steer(-30, 20)
sensors.color3.pauseUntilColorDetected(ColorSensorColor.Black)
music.playSoundEffect(sounds.systemGeneralAlert)
motors.largeBC.steer(30, 20)
sensors.color3.pauseUntilColorDetected(ColorSensorColor.White)
})
```
#### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick.
#### Differentiation
Program your robot to drive on “autopilot” along a given route. You will need to create a program that recognizes and responds to a dark line (or white line). You will create a line-following program and your robot will need to travel along the line without losing contact with it.
You will need to constantly debug your program in order to make your robot travel as smoothly as possible along the line.
### ~hint
Consider using these blocks in your solution:
```block
while (true) {
}
motors.largeBC.steer(0, 50)
```
> **- OR -**
```block
if (true) {
} else {
}
```
### ~
### Sample Solutions - Line Following in Loop
#### Method 1
1. While the Color Sensor detects the color black, start motors ``B`` and ``C`` (drive forward with a curve toward the line).
2. While the Color Sensor detects the color white, start motors ``B`` and ``C`` (drive forward with a curve away from the line).
3. Loop forever.
```blocks
forever(function () {
while (sensors.color3.color() == ColorSensorColor.Black) {
motors.largeBC.steer(-30, 50)
}
while (sensors.color3.color() == ColorSensorColor.White) {
motors.largeBC.steer(30, 50)
}
})
```
#### Method 2
1. If the Color Sensor detects the color black, start motors ``B`` and ``C`` (drive forward with a curve toward the line).
Else the Color Sensor detects the color white, start motors ``B`` and ``C`` (drive forward with a curve away from the line).
2. Loop forever.
```blocks
forever(function () {
if (sensors.color3.color() == ColorSensorColor.Black) {
motors.largeBC.steer(-30, 50)
} else {
motors.largeBC.steer(30, 50)
}
})
```

# Object Detection
Design ways to avoid accidents between vehicles and objects in the road.
![Deer in the road](/static/coding/object-detection/road-deer.jpg)
## Connect
Think about:
* In what driving situations can a car hit an obstacle?
* What do you need to be aware of to avoid collisions with obstacles?
* What causes traffic jams in high density areas?
## Construct
### Build
Build a @boardname@ vehicle that can avoid accidents between vehicles and objects in the road. Start by constructing this model:
[![EV3 Robot Driving Base](/static/coding/object-detection/ev3-robot-driving-base.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-ultrasonic-sensor-driving-base-61ffdfa461aee2470b8ddbeab16e2070.pdf)
Build an obstacle for your robot to detect. You can build the **cuboid model** out of LEGO bricks or an obstacle of your choice.
[![Cubiod block](/static/coding/object-detection/ev3-cuboid.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-cuboid-dc93b2e60bed2981e76b3bac9ea04558.pdf)
### ~hint
If clicking the above images doesn't open the instructions, right-click on the image and choose "Save link as..." to download the PDF.
### ~
### Check
Before you program, check:
* Are all the wires correctly connected from the motors to ports B and C?
* Are the wheels correctly installed?
* Are the wheels rotating freely?
* Are the wires connected from the Ultrasonic Sensor to port 4?
### Program
* Program your robot to detect any obstacles that might appear while the robot is moving forward (or backward).
* Make the robot stop when it detects an object that is less than 20 cm away.
Before you program, think about:
* How will you program the robot to detect obstacles?
* How will you program the robot to stop at obstacles?
* Which programming blocks will you use?
### ~hint
Consider using these blocks in your solution:
```block
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
})
motors.largeBC.steer(0, 50)
pauseUntil(() => true)
let near = sensors.ultrasonic4.distance() < 20
motors.stopAll()
```
### ~
### Sample Solution
1. Start the program when EV3 ``enter`` button is pressed.
2. Turn motors ``B`` and ``C`` on at speed ``50``.
3. Wait until Ultrasonic Sensor detects an obstacle at a distance of less than ``20`` cm.
4. Stops all motors.
```blocks
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
motors.largeBC.steer(0, 50)
pauseUntil(() => sensors.ultrasonic4.distance() < 20)
motors.stopAll()
})
```
### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the ``center`` button on the EV3 Brick to run the program.
## Contemplate
On the road, when a driver sees and object, they slow their car down before coming to a full stop.
Program your EV3 Driving Base to do the same.
If the Ultrasonic Sensor:
* Detects an object less than `10` cm away, make the robot stop.
* Detects an object between `10` and `20` cm away, make the robot slow down.
* Does not detect any object, continue to move at full speed.
### ~hint
Consider using this block in your solution:
```block
if (true) {
}
```
### ~
### Sample Solution
```blocks
loops.forever(function () {
motors.largeBC.steer(0, 50)
if (sensors.ultrasonic4.distance() < 10) {
motors.stopAll()
} else if (sensors.ultrasonic4.distance() < 20) {
motors.largeBC.steer(0, 10)
}
})
```
### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the ``center`` button on the EV3 Brick to run the program.
## Continue
* Get together with other building teams and make a traffic jam by placing all of your robots in a line with varying amounts of space between them.
* Have everyone start their robots at the same time and see what happens.
* Refine your programs so that all of the robots continue driving at the same speed with equal distances between them.
* Click on the JavaScript tab and experiment with changing the values in the code.
* Add a custom image or sounds from the Brick or Music menus.
### Share
* Share what you think “efficiency in programming” means.
* Explore the different solutions other programmers came up with.
* Create a video of your project, especially your final presentation and your robots performance. Explain some important features of your software program.
* Include an image of your program with comments.
* Add a team photograph!
Congratulations! What will you design next?

# Make A System That Communicates
## Connect
### Design Brief
Design, build and program a robotic system that follows a path and communicates its position at least twice along the way.
https://www.youtube.com/watch?v=6piMI1JPDQc
* Robotic systems are built from smaller, related subsystems. Look at the automobile system shown in the video. What subsystems can you see?
* What kinds of robots follow a path?
* What kind of system do you want to make?
### Brainstorm
Discuss different solutions to the design brief.
Think about:
* What kind of motorized mechanism can be used to control the movements of a robot?
* How can the robot sense where it is along the path?
* How can the robot communicate its position?

Build a path for your robot to follow. You can use electrical tape on a floor, or marker on paper. You can use objects as milestones to indicate a path that can be detected by either the Touch Sensor, Color Sensor, or Ultrasonic Sensor.
### Program
Before you program, think about:
* How will you program the robot to follow a path?
* How will you program the robot to communicate its position?
* Which programming blocks will you use?
### ~hint
Explore the different Motor and Sensor blocks in the programming menu.

### Sample Solution
[![Video: EV3 Track Rover](/static/lessons/make-it-communicate/ev3-track-rover.jpg)](https://legoeducation.23video.com/v.ihtml/player.html?token=79c99735f906403a4dd7f2909935983d&source=embed&photo%5fid=19857954)
The Track Rover follows a path using the color sensor. It identifies two locations by color.
Track Rover solution combines these building ideas:
* EV3 frames
* Tracks
* Color sensor 2
Two copies of the tracks are built: one for the right side and a mirror image for the left side.

### Sample Program Solution
This program works with the Track Rover. If you create a different robot, adjust the program to fit your solution.
Program summary:
* If the Color Sensor sees black, Motor B runs at -50 power and Motor C turns off.
* If the Color Sensor sees white, Motor B turns off and Motor C runs at -50 power.
* If the Color Sensor sees green, all motors stop and the green sound plays.
* The robot waits one second, then motors move forward.
* If the Color Sensor sees red, all motors stop, and the red sound plays.
* The robot waits one second, then motors move forward.
* Loops unlimited.
```blocks
forever(function () {
if (sensors.color3.color() == ColorSensorColor.Black) {
motors.largeB.run(-50)
motors.largeC.run(0)
} else if (sensors.color3.color() == ColorSensorColor.White) {
motors.largeC.run(-50)
motors.largeB.run(0)
} else if (sensors.color3.color() == ColorSensorColor.Green) {
motors.stopAll()
music.playSoundEffectUntilDone(sounds.colorsGreen)
motors.largeBC.run(-50)
} else if (sensors.color3.color() == ColorSensorColor.Red) {
motors.stopAll()
music.playSoundEffectUntilDone(sounds.colorsRed)
motors.largeBC.run(-50)
}
})
```

# Make It Move Without Wheels
## Connect
### Design Brief
Design, build and program a robot that can move itself using no wheels for locomotion.
![Make it move banner](/static/lessons/make-it-move/make-it-move-without-wheels.png)
Your robot will:
* Go a distance of at least 30cm
* Use at least one motor
* Use NO wheels for locomotion
### Brainstorm
In nature, creatures use many methods to get around. None of them, however, use wheels to move. Can we copy the method of animal locomotion with our robot? Using motors and legs, make a robot that can move without using any wheels.
## Construct
### Build
Think about a creatures movement for inspiration. Will you make the robot walk, crawl, hop, or wiggle? Your mechanism can be attached or unattached to the EV3 Brick. You can start by tinkering with the LEGO elements in the picture above and then build on.
### Building Hint
If you want some building help you can follow these instructions.
[![Toddle Bot](/static/lessons/make-it-move/toddle-bot.jpg)](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/toddle%20bot-3dcad146d7f5deac4753f93e9dcc0739.pdf)

### ~hint
If clicking the above image or link doesn't open the instructions, right-click on the link and choose "Save link as..." to download the PDF.
### ~
### Program
Before you program, think about:
* How will you program the robot to move?
* How will you program the robot to stop?
* How will you program the robot to display the distance moved?
Which programming blocks will you use:
* To turn on and turn off the motor or motors?
* To display the distance moved?
### Sample Code
Example code of a robot that moves without wheels using one motor:
* The robot moves with ``large motor D`` rotating at ``-100`` speed
* The robot moves for ``30000`` milliseconds (30 seconds)
* The robot stops
* The robot displays the text ``"30cm"``
```blocks
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
motors.largeD.run(-100)
loops.pause(30000)
motors.stopAll()
brick.showString("30cm", 1)
})
```
### Download and test
Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
## Contemplate
### Test and Analyze
Think about:
* Is the robot using something other than wheels to move? Trace the movement from the motor axle to the mechanism(s) that drives the robot forward, backward or sideways. Wheels can be used to stabilize the robot but not to drive it.
* Does the robot display the distance moved? Is it accurate? How do you know?
* What is one part of your design that worked well?
* What is a change that you need to make?
* What will you try next?
## Continue
### Personalize your project
* Add/remove LEGO elements to improve the way your robot moves. Will your robot walk, wiggle, hop, or slither? Will it move slower, faster or farther?
* Click on the JavaScript tab and experiment with changing the values in the code.
* Add a custom image or sounds by adding blocks from the Brick or Music menus.
* Does your robot resemble a creature? Add arts and crafts materials to your project.
## Communicate
* Create a video of your project, especially your final presentation and your robots performance.
* Explain some important features of your software program.
* Produce a building guide for your model by taking a series of photographs as you deconstruct it.
* Include an image of your program with comments.
* Add a team photograph!
Congratulations! What will you design next?

# Make It Smarter and Faster
## Connect
### Design Brief
Design, build and program a robotic creature that can sense its environment and respond by moving.
https://www.youtube.com/watch?v=y9-A_C_08KY
* What do the robots in the video need to be able to sense, plan, and act?
* What senses do humans have and why are they important to us?
* How many human-like senses do you see the robots demonstrating?
### Brainstorm
Discuss different solutions to the design brief.
Think about:
* What kind of creature can it be?
* How can it move?
* What does it need to be aware so that it stays safe, well fed and warm (or cool)?
* Is it looking for food, a safe place to hide or a warm place to soak up the sun?
* Will the creature need to move fast or slow?
* Will it need to turn?
* Will it need to go backward?

### Sample Solution
The Insect uses its Ultrasonic Sensor to sense danger and move away from a threat.
https://www.youtube.com/watch?v=PoeYoiXHHE4
<br/>
The Insect solution combines these building ideas:
* [EV3 Frames]
* [Leg 2]
* [Leg 3]
* [Ultrasonic Sensor]
Four copies of Leg 3 are built: one for the front left, one for the back right, and two mirror copies for the front right and back left.
Building Instructions:
[![Insect robot](/static/lessons/make-it-smarter/insect-bot.jpg)](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/insect-94b8a46f0dc5082c9d78ddb734626dc9.pdf)
### ~hint
If clicking the above images or links doesn't open the instructions, right-click on the link and choose "Save link as..." to download the PDF.
### ~
### Sample Solution
This program checks if the Ultrasonic Sensor senses something near.
The blocks inside the ``||loops:forever||`` loop have these actions:
1. Turn on the ``green`` EV3 Brick Status Light.
2. Wait for Ultrasonic Sensor to detect an object.
3. Turn on Motors ``A`` and ``D`` in opposite directions.
4. Wait for one and a half seconds (``1500`` milli seconds).
5. Reverse the direction of Motors ``A`` and ``D``.
6. Wait for one and a half seconds.
7. Stop all motors.
8. Make an insect chirping sound.
9. Loop continuously so that the insect wanders around when the Ultrasonic Sensor is detects something.
```blocks
forever(function () {
brick.setStatusLight(StatusLight.Green)
sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected)
motors.largeAD.tank(50, -50)
pause(1500)
motors.largeAD.tank(-50, 50)
pause(1500)
motors.stopAll()
music.playSoundEffectUntilDone(sounds.animalsInsectChirp)
})
```

Think about:
* Does your robot move when the sensor is activated?
* If not, what will you change to make the robots ability to sense and respond more obvious?
* What other behaviors can you add to the robot to make it more realistic?
Describe two ways you could improve your robot.

https://youtu.be/-AirqwC9DL4
## Do you have examples of program used in competitions?
The MakeCode team ran a team with friends and family in South Seattle and scored 175 points.
The programs used for the crane, swing, red blocks and ramp are at https://github.com/lego-marshmallows (the robot build is not detailled).
### Why can't I delete my program (*.uf2) files from the Brick?
There's a bug in the firmware which prevents you from deleting the programs (``*.uf2`` files) from your EV3 Brick. There isn't a firmware update to fix this yet.
We have prepared a special program that lets you delete UF2 files from the brick.
Download [these PDF instructions](/file-manager.pdf) and drop the PDF on the brick drive.
This will present you with an menu for deleting files.
For other common questions, try the FAQ page https://makecode.mindstorms.com/faq.
## Workarounds

In this project we will guide you through building a Driving Base Robot and programming it to move straight and turn. You will also build and Object Detector Module, and program it to detect an object. Its a good idea to have done the [Try](/getting-started/try) sequence first.
## Connect
What if your school had a multipurpose robot? How would you use it?
![Apple Picker Robot](/static/getting-started/02_ApplePickerRobot.jpg)
Would you use it to clean the school or plant trees?
## Build Your Driving Base Robot
Build the robot driving base:
[![EV3 Driving Base](/static/lessons/common/ev3-driving-base.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf)
### ~hint
If clicking the above image doesn't open the instructions, right-click on the image and choose "Save link as..." to download the PDF.
### ~
## Make It Move
**Code it:** Create a program that makes the Driving Base move forward and stop at the finish line, which is ``1`` meter away.
Start by building this program:
```blocks
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
motors.largeBC.steer(0, 50, 1, MoveUnit.Rotations)
})
```
* Drag a ``||motors:steer large motors B+C||`` block inside an ``||brick:on button||`` block.
* Click on the **(+)** sign.
* Change to ``1`` rotation.
### ~hint
**Hint:** You will have to modify the number of rotations until you find the number that matches the robot moving forward 1 meter and stopping.
### ~

# Coding in MakeCode
This guide helps users who are used to working with @boardname@ become familiar with using blocks in MakeCode.
## Snap together the blocks
Just like in LabView, blocks in the MakeCode editor can be dragged from the cabinet and snapped together
to create a sequence of program instructions.
Take a look a the LabView program below: it **starts**, turns on motor A, waits a second, and finally stops motor A.
![sequence of block](/static/labview/sequencing.png)
The blocks in MakeCode have similar functions and go together in the same way: they snap into the ``||loops:on start||`` block and then connect to each other vertically.
```blocks
motors.largeA.run(50)
pause(1000)
motors.largeA.stop()
```
Any block program can be converted to JavaScript and you can edit it as lines of code too.
```typescript
motors.largeA.run(50)
pause(1000)
motors.largeA.stop()
```
## Download to the EV3
Before you actually run your program on the EV3 Brick, you can first try it in the simulator. The MakeCode editor includes a simulator in the browser for you to test your code. You can make changes to your program and check them out it the simulator to make sure your code works the way want. The similator knows when you modify your code and it restarts automatically to run the new code.
Once you're ready to transfer your program to the EV3 Brick, click the ``|Download|`` button and follow the instructions.
## Single motors
This program controls a large motor on port A in several different ways. It sets just the speed and then sets speed for: an amount of time, angle of movement, and a number of rotations.
![Single motor blocks](/static/labview/motors.png)
```blocks
motors.largeA.run(50);
motors.largeA.run(50, 1000, MoveUnit.MilliSeconds);
motors.largeA.run(50, 360, MoveUnit.Degrees);
motors.largeA.run(50, 1, MoveUnit.Rotations);
motors.largeA.stop();
```
## Steering
The **steering** blocks let you to synchronize two motors at a precise rate. They can also specify the duration, angle, or number of rotations for the motors to turn.
![Steering blocks](/static/labview/steer.png)
```blocks
motors.largeBC.steer(0, 50);
motors.largeBC.steer(0, 50, 1000, MoveUnit.MilliSeconds);
motors.largeBC.steer(0, 50, 360, MoveUnit.Degrees);
motors.largeBC.steer(0, 50, 1, MoveUnit.Rotations);
motors.largeBC.stop();
```
### ~ hint
The **turn ratio range is -200, 200** unlike LabView who used -100,100.
### ~
## Tank
The **tank** blocks control the speed of two motors. These are commonly used for a differential drive robot. The blocks can also specify the duration, angle, or number of rotations.
![Tank block](/static/labview/tank.png)
```blocks
motors.largeBC.tank(50, 50);
motors.largeBC.tank(50, 50, 1000, MoveUnit.MilliSeconds);
motors.largeBC.tank(50, 50, 360, MoveUnit.Degrees);
motors.largeBC.tank(50, 50, 1, MoveUnit.Rotations);
motors.largeBC.stop();
```
## Coasting and braking
By default, all motors coast when any command used to move finishes. You can keep them from coasting with the ``||motors:set brake||`` block.
![Brake block](/static/labview/brake.png)
```blocks
motors.largeD.setBrake(true);
motors.largeD.run(50, 1, MoveUnit.Rotations)
```
## Inverting and regulating motors
If you wan to change the direction that a motor turns, use the ``||motors:set inverted||`` block.
![Brake block](/static/labview/invertmotor.png)
```blocks
motors.largeA.setInverted(true);
```
By default, the speed of motors is regulated. This means that if your robot goes up a hill,
the regulator will adjust the power to match the desired speed. You can disable this feature
using ``||motors:set regulated||``.
![Brake block](/static/labview/unregulatedmotor.png)
```blocks
motors.largeA.setRegulated(false);
```
## Brick
The **Brick** category has a number of blocks to display graphics on the brick screen.
![brick image](/static/labview/brickimage.png)
```blocks
brick.clearScreen()
brick.showImage(images.expressionsWink)
```
![brick status light](/static/labview/brickstatuslight.png)
```blocks
brick.setStatusLight(StatusLight.Off);
brick.setStatusLight(StatusLight.Red);
brick.setStatusLight(StatusLight.OrangePulse);
```
## Waiting (pausing)
It is quite common to have to wait for a task to finish or for a sensor state to change, such as when a touch button pressed. The ``||loops:pause||`` and ``||sensors:pause until||`` blocks provide a way for your program to wait for a period of time.
![pause for time](/static/labview/pausefortime.png)
```blocks
motors.largeD.run(50)
pause(1000)
motors.largeD.stop();
```
![pause for touch](/static/labview/pausefortouch.png)
```blocks
motors.largeD.run(50)
sensors.touch1.pauseUntil(ButtonEvent.Pressed)
motors.largeD.stop();
```
![pause for distance](/static/labview/pausefordistance.png)
```blocks
motors.largeD.run(50)
sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectNear)
motors.largeD.stop();
```
You can also use the ``||loops:pause until||`` block to wait on any [boolean](/types/boolean) expression. As your program runs, it waits until the condition (expression) inside becomes true.
```blocks
motors.largeD.run(50)
pauseUntil(() => sensors.touch1.isPressed())
motors.largeD.stop()
```
## Loops
![Single loop](/static/labview/loopinfinite.png)
```blocks
forever(() => {
motors.largeD.run(50, 1, MoveUnit.Rotations);
motors.largeD.run(-50, 1, MoveUnit.Rotations);
})
```
![While loop](/static/labview/while.png)
```blocks
for(let i = 0; i < 10; i++) {
motors.largeD.run(50, 1, MoveUnit.Rotations);
motors.largeD.run(-50, 1, MoveUnit.Rotations);
}
let k = 0;
while(k < 10) {
motors.largeD.run(50, 1, MoveUnit.Rotations);
motors.largeD.run(-50, 1, MoveUnit.Rotations);
k++;
}
```
## Variables
![Variable block](/static/labview/speedoflightvar.png)
```blocks
let light = 0;
forever(function () {
light = sensors.color3.light(LightIntensityMode.Reflected);
motors.largeD.run(light)
})
```
## Concurrent loops
You can start up multiple ``||loops:forever||`` loops that run at the same time. Actually, only the code in just one of the loops is really running at any exact moment in time. Each loop, though, gets a turn to run all of its code and this makes them run [_concurrently_](https://en.wikipedia.org/wiki/Concurrent_computing).
![Multiple loops running at the same time](/static/labview/multipleloops.png)
```blocks
forever(() => {
motors.largeD.run(50, 1, MoveUnit.Rotations);
motors.largeD.run(-50, 1, MoveUnit.Rotations);
})
forever(() => {
brick.showImage(images.eyesMiddleRight)
pause(1000)
brick.showImage(images.eyesMiddleLeft)
pause(1000)
})
```
## Conditional
The ``||logic:if||`` block allows you to run different code depending on whether some condition ([boolean](/types/boolean) expression) is `true` or `false`. Also, this is similar to the ``||loops:switch||`` block.
![Brake block](/static/labview/ife.png)
```blocks
forever(function() {
if(sensors.touch1.isPressed()) {
motors.largeD.run(50)
} else {
motors.largeD.stop()
}
})
```
## Random
The ``||math:pick random||`` block returns a random number selected from a range of numbers.
![Brake block](/static/labview/random.png)
```blocks
forever(function () {
motors.largeBC.steer(Math.randomRange(-5, 5), 50)
pause(100)
})
```
