I’ve gotten the IR receiver working and the codes pulled out that will be needed to turn on and off my projector. I’m having issues getting the IR LED to emit a signal that works.
I’ve followed as many examples and guides as I can without any results. In this documentation it says to use Pin 3. I just want to do a sanity check to make sure that is D3. I was looking at the datasheets and saw #3 might be TX. https://docs.particle.io/datasheets/photon-(wifi)/photon-datasheet/#jtag-and-swd
