Application Notes

1. Overview

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 [http://www.autohotkey.com/] 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.
