XINGYHENG 50 Pairs 5mm 940nm Infrared Diode LED Emission and IR Receiver

Q: Why are there two colors of leds? which one is the led and which one is the ir receiver?

The black is the receiver and the clear is the admitted. Unlike LED's, the short arm of the receiver is attached to the cathode (positive) side of the circuit.

Q: All the clear ir led's are emitting white light. are these supposed to generate visible light?

I have noticed any visible light from the clear bulbs. I have never looked in the dark at the output.

Q: Is the receiver a photo diode, photo transistor or photo resistor? It sounds like a photo transistor, but just learning distinction.

Fairly certain (90%) that it is a photo diode. If ur multi-meter has a diode function, u should be able to see a forward voltage drop of around .7v when forward biased. Hope this helps
