Hello, I've been trying to use the IRremote library (https://github.com/shirriff/Arduino-IRremote) to read an infrared signal sent from a remote control and then an infra red LED to emit the code read to a device (TV, Home Theater, etc.).
It was very easy and simple to make the receiver work, however, the emitter doesn't seem to be working and I can't even tell if the emitter is in fact emitting, I tried to do a simple blinking on digital pin 3 with a regular LED and it blinks just fine, then I switched to an IR LED and tried to use my Iphone to try to see any sign of light with no luck.
Is there any other way I can try to see if my IR LED is emitting? I'm currently using an Arduino Nano to emit the infra red signal to my devices and an Arduino Mini to receive the signal from the remote control, reading the documentation I could find they use the digital pin 3 to emit the signal, so I connected D3 to a 220ohm resistor and the resistor to the bigger "leg" of the IR LED and the smaller leg I just grounded, I tried to switch them as well with no luck though.
Thanks in advance
