Hi all, I would like to see if I could get a bit of help regarding multiplexing some LDR's (Light dependent resistors). :slight_smile: My end goal is to make a PCB with a grid of 13x7 LDR's (91 total) to measure the light output coming from a screen in many different points. I have never done multip…

Question on how to multiplex LDR's
