Hello guys so I've been experimenting with IR emitters and I have encountered the following problem.
Basically my IR emitters work on any Arduino I have except for the 3.3v mini pro. At first I thought the emitter needed more voltage but what happens is that if I "flash" the code on the 3.3v arduino while selecting the 5v 16Mhz mini pro in the tool menu it works normally, but if I flash it as a 3.3v (which it is) it no longer works.
futhermore this workaround only works if I have nothing else but the emitter wired into the arduino, if I connect for example an rgb strip (just two leds) the emitter stops working.
Anyone knows how to make an IR emitter work normally on a 3.3v mini pro?
thanks for help!
