I suppose I should start by introducing myself. My name is Mark, I am going for my Master's degree in digital design right now, and I am creating an Infrared emitting LED circuit, powered by 4.5v, into a 1/8" stereo phone jack. Pretty much I am making an infrared emitter that plugs into a headphone jack. Unfortunately, I am a bit stuck right now, and I was wondering if anyone could help me diagnose the problem. The LED is not lighting at all, and I tried it on my computer's camera, (which can detect IR because I tested it with my cable remote).
I am using a NPN transistor. I am using 3 silver oxide, 1.5v hearing aid batteries stacked together.
Here's the schematic:
Here's the circuit:
Any thoughts? Should I be using an NPN transistor? Can you not stack batteries together like that? (I superglued the outside..)
Thanks in advance,
-Mark
