I ask for help in the Arduino. forum and they do not have a clue what's going on. So am asking here.
I have a stepper motor with a slotted encoder disk to tell the controller a home position using an ITR9608-F Opto Interrupter. The problem is it acts like it sees the slot when it does not. The is random and never in the same place.. Even with the sensor removed. It should constantly rotate with the sensor disconnected. So what could be causing this random rotationdis?
I have tested the sensor out and in the circuit. Which makes me that controller is blow.
Here is the schematic of the sensor. Also is a short video showing what I am talking about.
