The Xmas Pi is a Christmas tree lined with controllable LED lights. The lights are controlled from an Arduino, and can play different colours and patterns.
The Arduino is controlled by a Raspberry Pi that acts as a webserver. The Pi talks to the Xmas Pi website and receives commands. This data is then sent to the Arduino, which controls the lights on the tree.
You can go to the Xmas Pi website and have a go at controlling the actual tree.
I am the the founder and editor of Codeduino. I'm a developer by trade, and a maker by night. I've been 'making' ever since being introduced to Arduino at university - my final year project was an Ableton Live controller based on Arduino.
