I am also looking to connect 12 LDRs to my Arduino UNO and was hoping to avail of the digital pins. I am only wishing to use the LDRs to produce 2 values, on and off.
This is for an audio project and I want to use the LDRs to trigger a note on or note off.
Is this possible?
I have heard about using multiplexers on the analogue pins but I don't really want to take the route as I have other plans for those pins
