I'd built a maze solver. When the solver makes a step (for example forward)
it uses the light sensor to search for a wall and the rotation sensor to
measure the distance it has traveled. If a wall is hit, the solver steps
back until it reaches the start position; when the full distance of a step
is traveled, the solver knows it could go this way and thinks about the
next step.
So there are two processes: one for the light sensor and one for the
stepper. The wakeup procedure waits until one process ends and checks which
process ended. The main program can act upon the outcome.
