hi,
im a newbie to this complexed type of electronics so plz excuse my mistakes.
what i am after is, a circuit to revers a DC MOTOR DRIVEN ACTUATOR(sort found on central locking on car doors) and also need to activate when a sensor senses movement. however it need to cut off when retracted and no signal from sensor is recieved. ive tried various 555 timer circuit but cannot get my head round it so any help would be greatly appreciated.
