Hi, I'm using a raspberypi 3 with hifiberry AMP+. I need to read 9 digital pins and minimum 2 analog, better 4 analog pins. I have an old radio and that I transformed to an music box. I want to use the potentiometers built in. Using encoders (as I read in other posts is not an option)
My ideas
- use an arduino to read all inputs and connect it to the raspberry via serial to get the values
- use a ADC converter like ADS1115 to read the analog inputs, use gpio of raspberrypi to read the digital inputs. Can I use the ads1115 with hifiberry and raspberry?
What would you recommend? Do you have further ideas ?
Happy holidays!
