Hi
have a 16f628a pic going to a uln2003a that controls 3 dpdt relays
relay 1 controls fwd / back motor1
relay 2 controls fwd / back motor2
relay 3 is to control which motor to control etc...
as in picture attached
eg: turn relay 3 on and relay 1 on and motor 1 turns fwd
i could do it with relay 1 and relay2 and 2 spst relays but i have only these 3 relays
any help????
MOD i did post this in a similar thread but it was better to start a new thread
