I'm trying to get my raspeberry pi to control a floor fan via IR. I'm stuck on getting the IR codes to be emitted through the IR LED. I'm not able to get the IR LED to turn on at all. I'm checking that it's burning by using an app on my phone. (I've verified the app is working by testing it with the fan's remote, I can see the remote's ir bulb going off when pressing the button)
I've setup my breadboard to turn on a normal LED which works but when I swap the LED with an IR LED I don't get anything. Below is the setup for the normal LED. I've tried 100 - 1kohm resistors, but no luck. I've swapped out the IR LED for others, I've checked and double checked the direction of the IR LED (and tried it both ways to be sure). I've gone through many tutorials with no luck.
It seems like this should be really easy which makes me think I'm missing something pretty simple. This is my first project with a raspberry pi and working with circuits. Any help would be very much appreciated.
