4. Turn Light 1 Red

5. 1 Move Right Algorithm Algorithm
When the right button is pressed: move the light to the right
Set CurrentPosition = 0 When the right button is pressed:
Change the CurrentPosition by ? 1

6. Algorithms When the up button is pressed:
Change the CurrentPosition by ?
Set the CurrentPosition light red
Show the lights
When the left button is pressed:

Set the CurrentPosition light red
Show the lights
When the right button is pressed:
Change the CurrentPosition by ?
Set the CurrentPosition light red
Show the lights
When the down button is pressed:
Change the CurrentPosition by ?
the CurrentPosition light red
Show the lights

7. Algorithms When the up button is pressed:
Change the CurrentPosition by -8
Set the CurrentPosition light red
Show the lights
When the left button is pressed:
Change the CurrentPosition by -1
Set the CurrentPosition light red
Show the lights
When the right button is pressed:
Change the CurrentPosition by 1

Show the lights
When the down button is pressed:
Change the CurrentPosition by 8
the CurrentPosition light red
Show the lights

8. New Algorithm
When the right button is pressed Clear the CurrentPosition light Change the CurrentPosition by 1 Set the CurrentPosition light red Show the lights

9. Move Right

10. Latest Algorithm
When the right button is pressed IF CurrentPosition + 1 is less than 63 THEN Clear the CurrentPosition light Change the CurrentPosition by 1 Set the CurrentPosition light red Show the lights END IF

11. Buzzzz
When the right button is pressed IF CurrentPosition + 1 is greater than 63 THEN Clear the CurrentPosition light Change the CurrentPosition by 1 Set the CurrentPosition light red Show the lights ELSE Turn the motor on Pause for 1 second Turn the motor off END IF

14. Challenge Algorithm When the red light reaches the Ball
Set CurrentPosition to 0
Turn the CurrentPosition light red
Set score to 0
Display the score on the micro:bit
Set Ball to 10
Turn the Ball light blue
Forever:
When the red light reaches the Ball
Change the score by 1
Set Ball to a random number between 0 and 63
Show the light
