Time controlled loops

14. Switch controlled by values
The switch takes an wire input at 1
If the condition is met the upper
path is taken, otherwise the lower
path is executed.

15. Switches controlled by sensors
The value of the light sensor in
port 3 is read. If it is greater than
50 turn right, less than 50 turn left.
