Right you clever lot.
I using a D1 Mini on a project, and need to have 2 analogue inputs, so time to get my head round multiplexing.
The 2 inputs I will be using are battery voltage, and analogue input via a sound board (I'll switch them as required), I've done some digging and came across the 74HC4051 and order a couple of eBay.
However after more digging I keep finding references to it discontinued, is this an old chip, is there a better one I should be looking at?
Thanks in advance
