So I've got this remote I'd like to control with my Arduino and I'd like to be able to use the buttons with the Arduino but I'm not sure how to accomplish this. Anyone got any ideas? I tried using a transistor but honestly I'm probably not using it right.. Thanks guys.
Firs you need to verify if when you press the button what happens... It can go from Low to High or from High to Low. Just use a voltmeter and draw a diagram.
Now, which voltage does the remote works?
Once you have both infos you might be able to test a few things like a P or a N mosfet, or even drive it directly from the Arduino pin.
