Lesson Objectives:
To program a device which can accelerate and decelerate.
Lesson Outcomes:
Lesson Outcomes:
ALL students will: Be able to create a program which can accelerate a motor.
MOST students will: Create a program which can accelerate a motor once a button is pressed.
SOME students may: Create a program which can accelerate and decelerate at the press of a button
Keywords:
Keywords:
Accelerate: To make something increase in speed
While Loop: We can execute a set of statements repeatedly as long as a condition is true.

Lets discuss this code!
Main Activities:
Main Activities:
Task 1: Accelerate at when it sees green!
Task 1: Accelerate at when it sees green!
Using the code above as a guide, create a program where the motor will accelerate to 20% power when a color sensor senses green.
Task 2: Decelerate when it sees red!
Task 2: Decelerate when it sees red!
Using the code above as a guide, add to your program so the motor will also decelerate the power when the color sensor senses red.
Take a screencast of your device working and explain what your program is doing.
Put this on your portfolio.
Extended Activity:
Extended Activity:
You may notice that you have to wait until the motor accelerates to 20%, before you can decelerate again to 0%.
Can you program the device so it doesn't have to wait?
Hint: Try using an IF function and a BREAK block.
