schematics, i tested all the resisters and the bridge rectifier. the diode. what it is doing is all messed up, so i think something is back feeding somewhere.
How it is supposed to work, the motor will run, until 1 of the OP gets broken, (by a hole in a spining piece attached, so the light doesnt get reflected back to sensor). So if OP1 and OP2 both are recieving light sighnals the motor will run, and when 1 of the OP doesnt recieve sighanal(motor moved piece into position) it should shut off. What it is doing, is running constant, as long as either of the OP get light. What i find really strange, is that it will run, no matter which part of the opb742(OP1 OP2) gets light, i thought it was 1 side emitting light, the other side recieving it. i did order 2 opb742, because they would only work if i shinned light from a flashlight directly into them(not by themselves, like they should) Any ideas on what could be broke that is allowing it to run constantly.
