Hey all I bought a Chinese double din radio in order to modify it to my liking. The main reason why i went with this one is that it had a few buttons and turn knobs on the front and i wanted to use an Arduino in order to "read" this inputs in order to do stuff within my software program.
However, I am not quite sure what I need to check in order to find out how to go about hooking up the rotary dial knob buttons to the arduino so that i can read each "click" that it makes. They also have a push button mode when you press on the front of the rotary dial.
As a side note I will be supplying the power to these so nothing on the board will be used except the physical rotary dial - aside from a few resisters it seems as well.
Here are a few images of the pcb layout:
And knowledge would be great as to how to go about hooking this up to read by the arduino :)
