The Ledsticker project aims to make a LED matrix controllable through USB. The
objective is to be able to glue the LED matrix to the back of a notebook lid and
program it to show static or animated drawings (which can even be generated from a
program), effectively turning it into a LED sticker.

A custom PCB was designed to have the LED matrix together with necessary components and a USB connector so it can be plugged to the computer. A command line application was also created to control the LED matrix through "stickers": plain-text files containing a sequence of commands to control the matrix.
