Was hoping to use two (2) of these sensors and have a few basic wiring questions…
Sensor is Fairchild QRB1134 infrared photoreflector
… tried to attach a data sheet…
My thoughts were to hook up:
(C) COLLECTOR digital input pin and10k pull up resistor to 5V
(E) EMITTER ground
(K) CATHODE ground
(A) ANODE ??? 5V and a resistor (what size?)
Are capacitors a good idea to smooth out the signal? I saw capacitors on a you tube video of an arduino project, again, what size? And what are they hooked up to, orientation, etc.
Appreciate any help from the experts on the forum!
