Reading out multiple buttons with a single ADC pin
In this video I show you how to read out multiple buttons using only one ADC pin.
I hope this is helpful to all of you who have not enough I/O pins left or to those you want to control loads of switches!
The resistor value you will generally use will be 10k or more so you don't draw loads of current, forgot to mention that in the video :)
If you like it leave me a comment and give me a thumbs up on youtube ;)
