Dear Experts there !
Can you please help me with circuit diagram and components for an IR Sensor (Transmitter and receiver) which can set digital pin to high / low when the beam between transmitter and receiver is broken. I would like to use this to detect an object in middle of the door so that I can stop the motor from running when an object is in middle of the door. Distance required between transmitter and receiver is about 48 INCHES
