This is my first post in this forum, I have been learning arduino with help of this forum for few years, Now I have to repair a Thermal printer for my friend. There is a Reflective Object Sensor on that Printer to identify when paper is empty.
As per the name on the Sensor, it is OPB706A sesnor with photoelectric transistor. As I am not into electronics field, I dont have an Idea how can I connect this sensor to arduino to get either digital or Analog input.
Thank you very much for the support, When I have checked the sensor, It is mounted on a PCB with 3 Wires Coming out. The connection is as Follows
Red Wire- Pin 1 of Sensor (collector of Transister)
Brown Wire- Pin 4 (Cathode of diode) and Pin 2 (Emitter of Transister)
Orange Wire - Pin 3 (Anode of diode)
