universal remote with headphone jack
Hello, I am trying to create a universal remote with my android. I have been trying to light a remote led using my android headphone jack, but I have had no success. I am running ARA Smart Rem on my android to produce the signal. I pressed the button on the remote and I can see the light on my webcam, but I can not see the light when I power it with the headphone jack. I connect a stripped headphone plug with a pair of with alligator clips to the led. The media volume is all the way up. How do I get the light to light up?
