I'm would like to build a circuit to control a stepper motor to go forward till the IR sensor detects gap then turn off motor, then send a signal again for it to move in reverse till it reaches a second gap and the motor turns off. Repeating the process back and forth. I'm hoping to implement a timer that will send the motor forward/reverse when needed. I have no clue what I'm doing just a little knowledge of stepper motors and circuits though I have never built any ciruits. I would imagine I could use a 555 chip to send the pulses to the stepper motter and use the IR Interrupter to stop the pulses when needed in each direction. Thanks for any help.
