Did you ever want to control a motor or servo from your computer simply by pressing a key? You can do this with a few easy lines of code by using AutoHotkey to run the command-line utilities that come with some of our USB products. AutoHotkey is a flexible, free, open-source utility for Windows that runs in the background. It can be set up to detect when a keyboard-combination is pressed and respond by running a custom script. Since these custom scripts can run Windows command-line programs, they can run the command-line utilities included with some of Pololu’s USB products. There are many possible applications of using AutoHotkey with our USB products, including home automation, computer case modifications, and computer-controlled art/displays. See Section 6 for examples of customer projects using AutoHotkey and Pololu products.
