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?** A: I have noticed any visible light from the clear bulbs. I have never looked in the dark at the output. **Q: Is there a datasheet for these two parts?** A: No. **Q: Is the receiver a photo diode, photo transistor or photo resistor? It sounds like a photo transistor, but just learning distinction.** A: 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.
