Hello, Let's say I want to connect a potentiometer and a LDR to 1 analog pin, and choose which of them I want to read with a toggle switch. Is this the way it should be done? Thanks! Edit: the pot is supposed to be a 10k of course, not 100k. [LDR Pot toggle_cr.png]

One option for that is an anlog multiplexer chip - a 16 to 1 analog multiplexor takes 1 analog pin and 4 digital pins to provide access to 16 signals...
