The RLA

 Synesthesia: The Reactive Lighting Array



Using an Arduino UNO, some LEDs and a bit of Pure Data I was able to hack together a surprisingly agile lighting array. The key ingredient is a wonderful library called Pduino which allows the Arduino to talk directly to Pure Data using the Firmata firmware. With this communication in place processing the audio and lucifying the sounds was no trouble at all. The RLA has a couple modes of operation, the most dramatic of which is reactive mode shown in the video above. The code is on my github under the project name 'RLA'.
