I have a motor that will move an arm 90 degrees. The voltage on the motor will flip so that the motor can move counter clock wise and clockwise. However I need a limiter circuit that will stop the motor once the arm is at 0 degrees and then again when it rotates clockwise to 90 degrees. I thought about using the N/C push pins at 0 and 90 degrees so that when the arm contacts the pins the motor stops, however, when the voltage flips it won't be able to move back the other direction since the N/C pins won't allow voltage as they broke the circuit conductivity. Not sure how to do this. It will need to be automated as the circuit controlling the motor movement will be automated. Any help appreciated. Thanks.
