I just used one Message. I still don't know how to do your test program. This will start and stop the motor as long as motion is detected in area 2. task main() { while(true) { if (Message()== 2) { OnFwd(OUT_A); Wait(100); Off(OUT_A); } } } -- Bob (...)

Vision Command offers very limited control of the RCX. It would be nice if you could use VC as a smart sensor from a more convention RCX program with full control.

Chris If I understand correctly you can add a series resister to each reed switch using the formula r=2^n*R.
