Recommendation for tri/quad digital pot?

[janjoh]

So, I really only want to drive three 5V analog volt meters so I figured a digital pot would be the way to go.

Any recommendations for which circuits would be painless to get running with electron?

Here is a digital pot and library that worked successfully for me with a Photon.

Need Support for MCP4142-104E/SN Potentiometer

@peekay123 [image] I ended up using your library here https://github.com/pkourany/MCP4261_Library to get the MCP4151 100K 256 step digital pot up and running on the Photon with absolutely zero problems That’s really nice after trying a different chip and 3 different libraries on the Arduino Uno all of which did not work right for me. I see you have some timing code for the Core built in and I was wondering if that code is necessary for the Photon or not. Thanks for the creating thi…
