Digital Potentiometer Circuit Schematic. One of the most common types of variable resistors is the potentiometer. We will connect this digital pot IC to the arduino microcontroller.
The specific digital potentiometer we will use in this circuit is the MCP4131 IC. The selected step on the ladder determines the resistance ratio of the digital potentiometer. The MCP line of potentiometers come in 5KO 10KO 50KO and 100KO meaning you can purchase the IC in any of these maximum resistance values.

I would like to use my Arduino for. The selected step on the ladder determines the resistance ratio of the digital potentiometer. This is why I chose a digital potentiometer that has 128 taps so we could make it step up and down with an 8-bit timer. I would like to use my Arduino for.
