Questions tagged [infrared]

Infrared radiation (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore generally invisible to the human eye.

Infared: some controllers send code into infinite loop

I have a piece of code that captures input from infrared and spits it out to the serial port. When I use it with a simple controller that comes with a typical kit, it receives the infrared code just fine for each button I depress. But when I try and…

Problem sending IR signal on Arduino Leonardo/Uno (IRRemote library)

I am trying to use my Arduino Leonardo (or Uno!) as a remote with the IRRemote library. The current setup picks up and decodes a signal perfectly, but fails to retransmit it. I have tested the infrared LED and it works. I have tested the setup…
