I would like to make a midi controller with 12 pots but Arduino has only 6 analog inputs. I have tried 4051b multiplexor (I can address 8 inputs using 3 Arduino’s digital outputs and 1 Arduino’s analog input).
So, because Arduino has 6 analog inputs, I’m going to use 6 multiplexors (one for each analog input) and the same 3 digital outputs to set multiplexor addresses.
When I made a test with one multiplexor I noticed that when I read the analog input it was noisy (for example 200 201, 199, 200, …) I’m very bad at electronics and I don’t know If noise will be a problem if I would use 6 multiplexors.
Thanks in advance
