+
+## 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:

+
+Before you program, check:

+
+### 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:

+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.

+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.

+# 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 robot’s 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?

+### 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?
+

+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.

+# 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 creature’s 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.

+
+### 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

+* 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.

+### 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
+
+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.stopAll()

+
+### 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. As a workaround, you can temporarily downgrade your firmware version, delete the files, and then upgrade back to the version that works with MakeCode.
+
+Follow these steps to downgrade your firmware version, delete the files, and uprgade back again:
+
+1. Go into **EV3 LabVIEW** - if it's not installed get it [here](https://education.lego.com/en-us/downloads/mindstorms-ev3/software)
+2. Plug in your EV3 Brick and start a new project
+3. Go to the **Tools** menu in the upper right corner, select **Firmware Update**
+4. In the **Firmware Update** dialog box, click on the **Show Details** button
+5. From the **Available Firmware Files** list, select **EV3 Firmware V1.09E**
+6. Click the **Update Firmware** button and wait for the update to complete
+
+Now the firmware version on the EV3 Brick will be **V1.09E**. Also, in the process, the downgrade deleted all of the saved programs from the EV3 Brick. To continue to use MakeCode, the firmware version must be at **V1.10E** or above. So, the Brick firmware needs to be upgraded again. If you don't know or do remember how to do this, see the **Upgrade your @drivename@** section in the [troubleshooting](/troubleshoot) page.
+
+For other common questions, try the FAQ page https://makecode.mindstorms.com/faq.

+# Coding in MakeCode
+
+This guide helps users who are used to work with @boardname@ to get familiar with using blocks in MakeCode.
+
+## Snap together the blocks
+
+Just like with 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

+```
+
+## 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();
+```
+
+## 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 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 will 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)
+})
+```

+# Line Detection
+
+## Objective
+
+Design ways to improve driving safety by helping to prevent drivers from falling asleep and causing an accident.
+
+![Car driving on highway](/static/lessons/line-detection/car-driving.jpg)
+
+## Connect
+
+Make sure that you can answer the following questions:
+
+* 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?
+
+Think about what you have learned, then document it. Describe the problem in your own words. Creatively record your ideas and findings.
+
+## Construct
+
+Start by constructing this model. Read the building instructions [here](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-color-sensor-down-driving-base-d30ed30610c3d6647d56e17bc64cf6e2.pdf) first.

+
+![Color sensor on the driving base](/static/lessons/line-detection/color-sensor-driving.jpg)
+
+## Program
+
+Autonomous cars need to recognize and respond to traffic lights automatically.
+First, 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.
+
+There are two coding tasks for this lesson:
+
+1. Create a program that will make your robot stop at red lights.
+2. Create a program that drives the robot forward until the Color Sensor sees red. The robot then stops.
+
+## Coding task 1 - Stop at red lights
+
+**Goal:** Create a program that will make your robot stop at red lights.
+
+### Step 1
+
+Create a program that drives the robot forward until the Color Sensor sees red. The robot then stops.
+
+Place a ``||motors:steer large B+C||`` block from ``||motors:Motors||`` under ``||loops:on start||``. Change the speed to 20%.
+
+```blocks
+motors.largeBC.steer(0, 20)
+```
+
+### Step 2
+
+Place a ``||loops:while||`` loop block under ``||motors:steer large B+C||``.
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+}
+```
+
+### Step 3
+
+Place a ``||sensors:pause until color detected||`` from ``||sensors:Sensors||`` inside the ``||loops:while||`` loop block. Change the color to red.
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+    sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+}
+```
+
+### Step 4
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause until color detected||`` block.
+
+Study the program...what do you think the program will do?
+
+**Hint:** The motors will run until the Color Sensor senses the color red, then all motors will stop. The motors will run until the sensor reading in the while block is true.
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+    sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+    motors.stopAll()
+}
+```
+
+### Step 5
+
+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.
+
+## Coding task 2 - Detect light changes
+
+**Goal:** Program your robot to drive forward again when the light changes from red to green.
+
+### Step 1
+
+Place a ``||loops:while||`` loop block under ``||loops:on start||``.
+
+```blocks
+while (true) {
+
+}
+```
+
+### Step 2
+
+Place a ``||motors:steer large B+C||`` block from ``||motors:Motors||`` inside the ``||loops:while||`` loop block. Change the speed to 20%.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+}
+```
+ 
+### Step 4
+
+Place a ``||loops:while||`` loop block under the ``||motors:steer large B+C||``  block.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+
+    }
+}
+```
+
+### Step 5
+
+Place a ``||sensors:pause until color detected||`` block from ``||sensors:Sensors||`` inside the ``||loops:while||`` loop block. Change the color to red.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+    }
+}
+```
+
+### Step 6
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause until color detected||`` block.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+        motors.stopAll()
+    }
+}
+```
+
+### Step 7
+
+Place a ``||loops:while||`` loop block under the second ``||loops:while||`` loop block.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+        motors.stopAll()
+    }
+    while (true) {
+
+    }
+}
+```
+
+### Step 8
+
+Place a ``||sensors:pause unril color detected||`` block inside the new ``||loops:while||`` loop block. Change the color to red.
+
+What do you think the program will do?
+
+**Hint:** The motors will run until the Color Sensor detects the color red, then it will stop all motors. The motors will also run and not stop when the color sensor detects the color green.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+        motors.stopAll()
+    }
+    while (true) {
+        sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+    }
+}
+```
+
+### Step 9
+
+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
+
+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.
+
+Think about what you have learned, then document it. Describe your pseudocode for this task. Creatively record your ideas, and findings.
+
+### Programming hint
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+sensors.color3.pauseUntilColorDetected(ColorSensorColor.Yellow)
+music.playSoundEffect(sounds.systemGeneralAlert)
+}
+while (true) {
+    while (true) {
+        sensors.color3.pauseUntilLightDetected(LightIntensityMode.Reflected, Light.Bright)
+        motors.largeB.run(10)
+        motors.largeC.run(-10)
+    }
+    while (true) {
+        sensors.color3.pauseUntilLightDetected(LightIntensityMode.Reflected, Light.Bright)
+        motors.largeA.run(-10)
+        motors.largeA.run(10)
+    }
+}
+```
+
+## Continue
+
+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.
+
+### Programming hint
+
+```blocks
+while (true) {
+    while (true) {
+        sensors.color3.pauseUntilLightDetected(LightIntensityMode.Reflected, Light.Bright)
+        motors.largeB.run(10)
+        motors.largeC.run(-10)
+    }
+    while (true) {
+        sensors.color3.pauseUntilLightDetected(LightIntensityMode.Reflected, Light.Bright)
+        motors.largeB.run(-10)
+        motors.largeC.run(10)
+    }
+}
+```
+
+## Share
+
+Consider the following questions:
+
+1. What challenged you?
+2. Where there any surprises?
+3. How could you improve your program?
+4. Could your program have been more streamlined?
+5. Have you used too many blocks?
+6. Is there a more efficient way of building your program?
+7. How could your program be used in real-world scenarios?
+
+Think about what you have learned, then document it. Creatively record and present your ideas, creations, and findings.

+
+A "console" is a place for a user to see special messages from a device. It could be  something connected to a serial port, a display that shows text, or even a text file. A console is typically used as a place to send information that is added to a message _log_ (a record of messages that are sent from a device). Your program can send log messages using the [console](/reference/console) functions. The MakeCode editor has a console view that lets you see the console output when your program runs in the simulator.
+
+On the EV3 Brick, the screen can serve as a console too and you can make your console output go there. Before using the console log functions, set the screen as the console output location.
+
+## Example
+
+Direct the console output to go to the screen. Show 20 values on the screen. Use the up and down buttons to scroll through the values.
+
+```blocks
+console.sendToScreen()
+for (let index = 0; index <= 20; index++) {
+    console.logValue("index", index)
+}
+```
