2. Learning Outcomes Understand While Loop
Program Edison to move in any direction

4. Activity 1 – Drive in square shape

6. EdPy (Edison and Python)
It’s a high level language was first released in 1991.

7. While Loop Loop : is to repeat the process over and over again
While represent an infinite loop.

8. Activity 4 – Page 48
The program will repeat forever since you used a while loop and made the condition true.

9. Activity 5 – Page 49 #-------------Setup---------------- import Ed
Ed.EdisonVersion = Ed.V2
Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM
# Your code below
while True:
Ed.PlayBeep() # Beep
Ed.LeftLed(Ed.ON) # Turn the left LED ON
Ed.RightLed(Ed.ON) # Turn the right LED ON
Ed.TimeWait(1, Ed.TIME_SECONDS) # Wait for 1 seconds
Ed.LeftLed(Ed.OFF) # Turn the left LED OFF
Ed.RightLed(Ed.OFF) # Turn the right LED OFF

10. Edison Drive System
The drive system used by Edison is : Differential drive
This drive allows Edison to move in any direction
In EdPy there is a function called Ed.drive which lets you control both motors

11. What are Functions Direction ( Forward – Backward – Stop)
Functions are pieces of code that perform a certain task depending on one of the following input
Direction ( Forward – Backward – Stop)
Speed ( 1-10)
Distance (Ed.CM – Ed.INCH – Ed.TIME)

12. Activity 5– Page 52
# Setup
import Ed
Ed.EdisonVersion = Ed.V2
Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM
# Your code below
# Drive the left motor forward at half of the speed for unlimited distance
Ed.DriveLeftMotor(Ed.FORWARD, Ed.SPEED_5, Ed.DISTANCE_UNLIMITED)
# Drive the right motor forward at half of the speed for unlimited distance
Ed.DriveRightMotor(Ed.FORWARD, Ed.SPEED_5, Ed.DISTANCE_UNLIMITED)
# Wait for 3 seconds
Ed.TimeWait(3, Ed.TIME_SECONDS)
Program Edison to move 3 seconds at speed =5. turn both motors at the same time

13. Activity 6– Page 53
# Setup
import Ed
Ed.EdisonVersion = Ed.V2
Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM
# Your code below
Ed.DriveLeftMotor(Ed.BACKWARD, Ed.SPEED_8, Ed.DISTANCE_UNLIMITED)
Ed.DriveRightMotor(Ed.BACKWARD, Ed.SPEED_8, Ed.DISTANCE_UNLIMITED)
Ed.TimeWait(4, Ed.TIME_SECONDS)
Program Edison to move 3 seconds at speed =5. turn both motors at the same time

14. Be Fast and Program First to be a winner
Program Edison to beep and turn both LEDs ON for 1 seconds and then to move 3 seconds at speed =4. turn both motors at the same time

15. Turning Edison using Angle
First, make the speed of the motors different from each other, based on which direction you want Edison to turn.
Then, control the timing of the rotation until you get the angle you need.
It is important to note that the timing values depend on:
the speed of the motors.
the surface on which the robot is driving.
the battery life.

16. Activity 7– Page 55 #-------------Setup---------------- import Ed
Ed.EdisonVersion = Ed.V2
Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM
# Your code below
Ed.DriveLeftMotor(Ed.FORWARD, Ed.SPEED_6, Ed.DISTANCE_UNLIMITED)
Ed.DriveRightMotor(Ed.STOP, Ed.SPEED_8, Ed.DISTANCE_UNLIMITED)
Ed.TimeWait(800, Ed.TIME_MILLISECONDS)

17. Activity 8– Page 56

18. Activity 9– Page 56 #-------------Setup---------------- import Ed
Ed.EdisonVersion = Ed.V2
Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM
# Your code below
# Drive both motors forward at a speed of 9 for 30 centimetres
Ed.Drive (Ed.FORWARD, Ed.SPEED_9, 30)
