Today, I've released my first library: DigiPot, a library for interfacing with MCP42X1 digital potentiometers.
It's a pretty simple library, but hopefully will help people get these things working "off the shelf".
As it is my first ever attempt at a library, it's sure to have mistakes, so please tell me if you happen to find any. Also, if you see room for new features or improvements, let me know as well. Download the zipped file below, including the readme containing basic structure.
