Jonathan Bumstead built an interactive instrument that uses an Arduino Uno to control the LED lights, capacitive touch sensors, and a MIDI output.
The LED Eclipse uses capacitive touch sensors positioned around the perimeter of the device to control ten LEDs and a MIDI signal. For all the programs I wrote for the eclipse, the idea is pretty much the same: determine which sensors are touched and then update the LEDs and MIDI output. In the video posted [on Maker Share], you can check out some of the programs that I wrote.
The instrument is well constructed and, as displayed in the video, can be adapted to fulfill several different uses. I liked watching Bumstead using the LED Eclipse as a circular piano, but had to fight back long suppressed memories of sleepless nights when he began using it to play Simon. I thought four buttons was hard. I can’t imagine what that game is like with ten!
