hello guys,
So lately I've been experimenting with IR receivers for a project and have been using a HX 1838 module bought from aliexpress. The issue is that I use it without any kind of problem on my arduino uno and nano, but If I use the exact same code with the exact same wiring on the 3.3v arduino mini pro it no longer works.
to clarify what I mean, the mini pro does detect that some kind of infrared is being sent but it prints only question mark in the serial monitor instead of the number of the received signal. voltage shouldn't be a problem as far as I understood, I also tried using it with 3.3v only my uno and the receiver works just fine.
Anyone can help me understand why it doesn't work?
thank you very much
