I want to control a FM radio with a arduino. I want to do it in a way so that I bypass the potentiometer.
Some background information,
I started this project some time ago but I just can't figure it out.
I discovered a certain kind of paint that detects when being touched, the piece that detects it is a touch board (links below). This board works with the arduino IDE and has the same layout as a arduino UNO and can also be used as one.
My idea was that i could paint a radio on the wall (with normal paint) and use the 'touch paint' to mark the buttons, so when you for example press volume up the radio gets louder.
I have figured out how to detect touch, but now comes the radio part. My first idea was to do it with motors, but these just weren't precise enough. Then someone recommended to replace the potentiometer (that changes both the FM-station and the volume) with an analog-output.
Can I just pop the potentiometer off and connect the analog-output to the potentiometer output?
If not, what should I do instead. (Please keep in mind that I'm not that advanced with all this :D)
Thank you for reading, I hope someone can help me.
