OVERVIEW
In some Arduino projects we will end up using Potentiometers.
The potentiometer (or pot, as it is more commonly known) converts rotary or linear motion into a change of resistance that can be read by an Arduino analog pin.

OVERVIEW
Sometimes while building a project, you run out of inputs on your Arduino to connect multiple switches.
For example the DigiSpark is great for small enclosures, but it doesn’t offer much in ways of inputs…
