Hello. I'm making a robot using the 28 pin project board. Because it has motors and a servo I decided to make use of the separate power supply facility for the outputs, thinking that would solve the problem of electrical noise. It has a Sharp IR sensor for object avoidance. Alas, when it's running it keeps "seeing" objects which aren't there - it doesn't run forwards for very long without going unnecessarily to the "avoid" subroutine. I checked it with a program that just gets it to light LEDs, red for too close, green for OK. It behaves very nicely.
Does this mean I need to put capacitors across the motors anyway? And the servo? Thanks
