First, here’s a video:

I got the digital potentiometer working! It was very simple using the SPI library built into the Arduino software. All you have to do is address the chip and then write it a value between 0 and 255 to set the resistance value. Here is the code for this version, I’ve cleaned it up a bit since last time:

If you have questions about the code please leave it in the comments.

Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone, but proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
