A lot of us know what it’s like to be using the same commands and processes on the computer, over and over again. Well Andrew has created a simple little device that allows you to program in a sequence of keystrokes. Then, with the push of a button, those keystrokes are replayed over a USB connection. It was created using a rotary encoder with a built-in push button switch, and is programmed using an innovative and slightly quirky interface that doesn’t require any custom software. All you need is a text editor like Notepad (Windows) or gedit (Linux)! This is a great submission that shows you don’t need to use Arduino for everything, nor require custom software to code it.

Andrew even wrote up his own tutorial!
