Hi guys,
I've got a project, I'm trying to interface my car's steering wheel controls into an arduino. The problem is that the controls are already interfaced to my car CD player. I want to split the signal and sent it into an arduino ALSO so I can control a secondary device. If I plug the lines into the AI of the arduino, the car CD player has a fit. So the arduino AI pins are doing something to the existing circuit that is undesireable.
Is there a way I can buffer the lines so I can get the signal into the arduino without affecting the existing circuit?
Thanks guys,
-Steve
