I'm new at multiplexing with arduino (I use arduino from some years), and -as title says- I'd like to learn. I'm trying to build an expandible system with 3 sensors, and I'd like to use a 74hc595b1 to link them, leaving some pins free. My first question is: is It possible? And second, can you kindly link me a simple -but very simple- example about multiplexers in arduino? Thankyou!

For connecting 8 analog devices to an Arduino, using only 3 Arduino pins, look at say a 4051 multiplexer IC: 4051 example
