+# 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 LEGO MINDSTORMS vehicle that can park itself safely without driver intervention.
+Start by constructing this [model](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf).
+
+![EV3- Robot Driving Base](/static/coding/autonomous-parking/ev3-robot-driving-base.jpg)
+
+### Checks
+
+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)

+# 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 LEGO MINDSTORMS vehicle that can help prevent drivers from falling asleep and causing an accident.
+
+Start by constructing this [model](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-color-sensor-down-driving-base-d30ed30610c3d6647d56e17bc64cf6e2.pdf):
+
+![EV3 robot with color sensor](/static/coding/line-detection/ev3-robot-color-sensor-down.jpg)
+
+Build red and green “lights” for your robot to detect. You can use LEGO bricks, colored tape, or marker on white paper. Read the building [instructions](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/color%20squares-0a88dfd98bb2e64b5b8151fc422bae36.pdf).
+
+![IMAGE: Color Squares](/static/coding/line-detection/ev3-color-squares.jpg)
+
+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?
+
+![IMAGE: 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.pauseForColor(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.pauseForColor(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.pauseForColor(ColorSensorColor.Red)
+    motors.stopAll()
+    sensors.color3.pauseForColor(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

+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.pauseForColor(ColorSensorColor.Black)
+    music.playSoundEffect(sounds.systemGeneralAlert)
+    motors.largeBC.steer(30, 20)
+    sensors.color3.pauseForColor(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.
+

+
+Consider using these blocks in your solution:

+
+### ~
+
+### Sample Solutions
+
+#### Line Following in Loop
+
+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.

+```
+
+#### Line Following in Loop
+
+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).

+* 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?

+### ~
+
+### 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.

+### 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.

+## 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.

+
+### 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?

+### Sample Solution 
+
+[Video: EV3 Track Rover](/static/lessons/make-it-communicate/trackrover.mp4)
+
+The Track Rover follows a path using the color sensor. It identifies two locations by color.

+
+### 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.

+
+### Design Brief
+
+Design, build and program a robot that can move itself a distance of at least 30cm, using at least one motor, using NO wheels for locomotion.
+
+### Brainstorm
+
+Discuss different solutions to the design brief.
+
+Think about:
+
+How can robots move without wheels? For example, how will you:
+* Connect the motor(s) to something to make the robot walk, crawl, or wiggle?
+How will you program the robot to move? For example, which programming blocks will you use to:
+* Turn on and turn off the motor or motors?
+* Display the distance moved?
+
+### Select the Best Solution
+
+Describe the solution that you have agreed to build and program.
+
+Think about examples from your brainstorming discussion. Then explain why you chose this solution for the design brief.

+
+### Sample Solution 
+
+This program checks if the Ultrasonic Sensor senses something near. 
+
+This program:
+
+* Turns on the green EV3 brick Status Light
+
+```block
+brick.setStatusLight(StatusLight.Green)
+```
+
+* Waits for Ultrasonic Sensor to detect an object
+
+```block
+sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected)
+```
+
+* Turns on Motors A and D in opposite directions
+
+```block
+motors.largeAD.tank(50, -50)
+```
+
+* Waits for one half of a second (1500 milli seconds)
+
+```block
+pause(1500)
+```
+
+* Reverses the direction of Motors A and D
+
+```block
+motors.largeAD.tank(-50, 50)
+```
+
+* Waits for one half of a second
+* Stops all motors
+
+```block
+motors.stopAll()
+```
+
+* Makes an insect chirping sound
+
+```block
+music.playSoundEffectUntilDone(sounds.animalsInsectChirp)
+```
+
+* Loops so the insect wanders around when the Ultrasonic Sensor is triggered
+
+```blocks
+forever(function () {
+    brick.setStatusLight(StatusLight.Green)
+    sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected)
+    motors.largeAD.tank(50, -50)
+    pause(1500)
+    motors.largeAD.tank(-50, 50)

+# Coding in MakeCode
+
+This guide helps users who are used to the LabView LEGO Minstorms editor quickly 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
+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 @boardname@, 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 @boardname@, 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)
+})
+```

+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 for color||`` from ``||sensors:Sensors||`` inside the ``||loops:while||`` loop block. Change the color to red.
+ 
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+    sensors.color3.pauseForColor(ColorSensorColor.Red)
+}
+```
+
+### Step 4
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause for color||`` 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.pauseForColor(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 for color||`` 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.pauseForColor(ColorSensorColor.Red)
+    }
+}
+```
+
+### Step 6
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause for color||`` block.  
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseForColor(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.pauseForColor(ColorSensorColor.Red)
+        motors.stopAll()
+    }
+    while (true) {
+        
+    }
+}
+```
+
+### Step 8
+
+Place a ``||sensors:pause for color||`` 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.pauseForColor(ColorSensorColor.Red)
+        motors.stopAll()
+    }
+    while (true) {
+        sensors.color3.pauseForColor(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.pauseForColor(ColorSensorColor.Yellow)
+music.playSoundEffect(sounds.systemGeneralAlert)
+}
+while (true) {
+    while (true) {      sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeB.run(10)
+        motors.largeC.run(-10)
+    }
+    while (true) {
+        sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.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.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeB.run(10)
+        motors.largeC.run(-10)
+    }
+    while (true) {
+        sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.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.

+Place a ``||brick:show string||`` block under ``||motors:stop all motors||``.
+Change the `"Hello World"` text to `"30 cm"`.
+
+The ``||motors:tank large B+C||`` will run for `9` rotations when the **center** button is pressed on the EV3 brick then stop and display "30 cm" on the EV3 Brick’s screen.
+
+```blocks
+motors.largeBC.tank(-60, 60, 9, MoveUnit.Rotations)
+motors.largeBC.stop()
+brick.showString("30 cm", 1)
+```
+
+### Step 4
+
+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.

+# send To Screen
+
+Direct the console output to go to the @boardname@ screen.
+
+```sig
+console.sendToScreen();
+```
+
+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 @boardname@, 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++) {

+## Separate tasks #tasks
+
+As an example, you could have a small task that checks the battery level and gives a warning when it drops below 15 percent. This is placed inside a ``||control:run in parallel||`` block:
+
+```block
+let powerCheck = false;
+
+control.runInParallel(() => {
+    while (!powerCheck) {
+        if (brick.batteryLevel() <= 15) {
+            brick.setStatusLight(StatusLight.RedFlash)

+        } else {
+            pause(5000);
+        }
+    }
+})
+```
+
+The code the main program just drives the brick in a constant pattern until the battery check in the parallel task says that the battery level is too low.
+
+```block
+let powerCheck = false;
+while (!powerCheck) {
+    motors.largeBC.tank(50, 50, 5, MoveUnit.Seconds)
+    motors.largeBC.steer(5, 50, 6, MoveUnit.Rotations)
+}
+motors.stopAll()
+```
+
+## #example
+
+Tank the brick in a pattern until the battery warning variable is set. Have a separate task check the battery level and set a warning variable when the level is below `5` percent.
+
+```blocks
+let powerCheck = false;

+# pauseUntil
+
+Pause until the timer counts up to a number of milliseconds.
+
+```sig
+control.timer1.pauseUntil(0)
+```
+
+When code in a block comes to a **pauseUntil**, it will wait until the timer count reaches the number of milliseconds you say. Code in blocks like **forever** and **runInParallel** will keep running while the current code is paused.
+
+The time number you give is the number of milliseconds past the running timer count. If the timer is currently at `25000` milliseconds and you want to pause for `10` seconds, then use a pause time of `35000`. If you want your pause time number to match the actual wait time, then [reset](/reference/control/timer/reset) the timer first.
+
+## Parameters
+
+* **ms**: the [number](/types/number) of milliseconds that you want the timer to count up to. For seconds, convert to milliseconds: 100 milliseconds = 1/10 second and 1000 milliseconds = 1 second.
+
+## Example

+# reset
+
+Reset the elapsed time of the timer back to `0`.
+
+```sig
+control.timer1.reset()
+```
+
+A timer starts counting from `0` when your program starts. It's time value always gets larger as your program runs. Maybe you want to meausure how long some task takes to finish or you want to do some action  only for a little while. A timer can keep track of the time it takes to do it.
+
+Resetting the timer sets the time value to `0` so the next time you check the time it's exactly the amount of time that has _elapsed_. Otherwise, you need to remember a start time value and then subtract it from the current time. 
+
+## Examples
+
+### Press time
+
+Find out how much time goes by between presses of the `enter` button on the brick.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {

+
+```blocks
+let startTime = 0
+let timing = false

+# run
+
+Set the rotation speed of the motor as a percentage of maximum speed.
+
+```sig
+motors.largeA.run(50)
+```
+
+The speed setting is a pecentage of the motor's full speed. Full speed is the speed that the motor runs when the brick supplies maximum output voltage to the port.
+
+If you use just the **speed** number, the motor runs continously and won't stop unless you tell it to. You can also give a value for a certain amount of distance you want the motor to rotate for. The **value** can be an amount of time, a turn angle in degrees, or a number of full rotations.
+
+If you decide to use a **value** of rotation distance, you need to choose a type of movement **unit**.
+
+## ~hint
+
+If you use a number of milliseconds as movement units, then you don't need to include the unit type.
+
+To run the motor for 500 milliseconds:
+
+```block
+motors.largeA.run(50, 500)
+```
+
+## ~
+
+Here is how you use each different movement unit to run the motor for a fixed rotation distance.
+
+```blocks
+// Run motor for 700 Milliseconds. 
+motors.largeA.run(25, 700, MoveUnit.MilliSeconds);
+
+// Run motor for 700 Milliseconds again but no units specified. 
+motors.largeA.run(25, 700);
+
+// Run the motor for 45 seconds
+motors.largeA.run(50, 45, MoveUnit.Seconds);
+
+// Turn the motor for 270 degrees
+motors.largeA.run(50, 270, MoveUnit.Degrees)
+
+// Turn the motor at full speed for 9 full rotations
+motors.largeA.run(100, 9, MoveUnit.Rotations);
+```
+
+## Parameters
+
+* **speed**: a [number](/types/number) that is the percentage of full speed. A negative value runs the motor in the reverse direction.
+* **value**: the [number](/types/number) of movement units to rotate for. A value of `0` means run the motor continuously.
+* **unit**: the movement unit of rotation. This can be `milliseconds`, `seconds`, `degrees`, or `rotations`. If the number for **value** is `0`, this parameter isn't used.
+
+## ~hint
+
+** Reverse is negative speed**
+
+Turning the motor in the opposite direction (reverse) is simple. Reverse is just a negative speed setting. To drive the motor in reverse at 25% speed:
+
+```block
+motors.largeB.run(-25)
+```
+
+## ~
+
+## Examples
+
+### Drive the motor for 20 seconds
+
+Run the motor connected to port **A** continuously. Pause 20 seconds and then stop the motor.
+
+```blocks
+motors.largeA.run(75)
+pause(20000)
+motors.largeA.stop()
+```
+
+### Backwards motion
+
+Run the motor connected to port **A** in reverse. Pause 5 seconds and then stop the motor.
+
+```blocks
+motors.largeA.run(-60)
+pause(5000)
+motors.largeA.stop()
+```
+
+### Run the motor for 35 rotations
+
+Run the motor connected to port **B** for 35 full rotations and then stop.

+# set Regulated
+
+Tell a motor to regulate its speed or not.
+
+```sig
+motors.largeA.setRegulated(true)
+```
+
+In order for a motor to always rotate at a constant speed it needs regulation. This means that the motor control electronics need to continously measure how much rotation has happened. The controller takes several rotation counts for a small amount of time and compares them to see if the speed is changing. The output power is adjusted if the controller detects that the motor is running too slow or too fast.
+
+If it's not regulated, your motor can change from the speed that you've set for it. Some examples are if your brick is driving forward and bumps into an object or it drives up a slope creating more load on the motor. In theses situations, if your motor speed is regulated, the controller will boost the power to the motor to keep it's speed from slowing down. Another example is when you run the motors to drive your brick down a slope. In this case, the motors would go faster than the speed you set for them if not regulated. To regulate this the controller reduces the power output to the motors to keep the brick from going faster.
+
+Motor regulation is always set to **ON** when your program first starts or the motor is reset.
+
+## Paramters
+
+* **value**: a [boolean](/types/boolean) value which means that the motor speed is regulated if `true`. The motor speed is not regulated when this is `false`.
