Dr. Megan Smith and I [krazatchu] have cooked up a circuit board to control Christmas lights. It’s Arduino compatible, based on the Mega328 and has a microphone, audio line in and a light sensor. It can switch 7 strings of lights with the ULN2003 transistor array. It also has Infrared for communications, to work with a TV remote or to talk among themselves to coordinate lighting events (I’ll be using some code from my firefly project: http://www.lumipendant.com/).
We will be giving workshops to assemble and program these controllers early December at ArtsCourt, Ottawa, Ontario Canada. The first application will blink a morse code Christmas message. We have named the project: “Hack UR Baubles”.
