The X9C series of digital potentiometers feature a simple 3 wire control interface, provide 100 steps of wiper adjustment, and can optionally save the wiper position for automatic recall of the setting after power on.
Here's an Arduino Uno sketch showing how easy it is to control and use the X9C family of digital pots.
This is a follow up to two previous videos:
