"Web5 mei 2024 · If you are wanting to detect any combination of keys being pressed then you can't do this:- The A/D in the arduino is only 10 bits, giving you a theoretical maximum of 10 keys. In practice 4 to 6 keys is the maximum. You would require a 16 bit D/A and it is quite unfeasible to do this with simple resistors because of the tolerances you would need. " - Key matrix pencil
