Hi,I have TCND5000 Reflective Optical Sensor with PIN Photodiode Output.I think function of this same as tcrt5000.here I am connecting Anode of IR Led to 5v with 100ohm of resister and collecter is also connect to 5v with 5k ohm resister.and cathode of both connects to ground.the output is taken from the collector of photo transistor which I connect to Arduino Pin of A1.when I open a serial terminal I get constantly 98 98 98.........this value is not changing if I take any object near to TCND5000.help me. is there I need to connect any Op-amp IC.
