Programming Example 3 – Bumper
If the front bumper has been fitted then the left bumper switch will be
connected to Input Pin C.1 and the right bumper switch will be
connected to Input Pin C.3.
A bump on the left will set ‘Input Pin C.1’ to 1, a bump on the right will
set ‘Input Pin C.3’ to 1, a central bump will set both ‘Input Pin 1’ and
‘Input Pin C.3’ to 1. The values of ‘Input Pin C.1’ and ‘Input Pin C.2’ can
therefore be used to determine what appropriate action to take when a
bump or collision occurs.
This program will light the left LED eye if the left bumper is pressed and
the right LED eye if the right bumper is pressed
