I would like to have a grid of potentiometers say 8 x 8 though I may need to increase this, I would like to be able to cycle through them and read their values repeatedly. I realise I need to use a multiplexer config and wondered what the best way of doing this might be. I’ll use 10k resistors and I’m open to ideas on the arduino board I choose but I’m hoping something with 4 or so analogue pins would be fine.
The grid of pots will be used to control a midi synth.
What I am thinking at the moment is that I use maybe 4x spark fun 16 channel mux board or maybe 1 of these with 16 4 channel ICs (something like CD74HC4052E) effectively converting those 16 sparkfun channels into 64.
But then I thought is there a way of multiplying the mux ics, so for example 3 ICs would be 444 giving me the 64 channels. At this point I realised I haven’t much of a clue, and I searched this forum and the internet and struggled to source something I could understand or was directly relevant. So I thought I’d ask here.
What would you do as a solution?
