Ever tear open a potentiometer? If you haven’t, you can still probably guess what’s inside. A streak of resistive material with some kind of contact that moves across it as you rotate ...

Here is a quick look at how contactless potentiometers work, where they are used, and why they are gaining ground.

Experimental The MCP_POT library implements access to MCP digital potentiometers. These devices have 1 or 2 potentiometers, 10 KΩ, 50 KΩ and 100 KΩ and communicates over SPI. The library supports both ...

If you ever wanted to adjust a circuit using a digital version of a potentiometer (variable resistor) controlled by an Arduino then this is the easy way to do it - and at a price that won't break the ...
