LED Wall

An interactive LED matrix based on WS2812b LEDs

The Idea

A LED Matrix which can be used as a display to play games or to show different information (like the current weather conditions)

The Architecture

The main ingredients are:

• Raspberry PI (Version 2)
• Arduino Uno
• Many LW2812b LEDs

Python

For easy color manipulation as well as different hardware setups I wrote a python library. To get started, read the documentation of the Display class.
