Othermill-Engraved Circuit Board Powering Projects at Moogfest @othermachine @moogfest
If you’re attending Moogfest from May 19-22 in Durham, North Carolina, be sure to swing by that city’s downtown CCB Plaza to check out the interactive project RTP Convergence by the Brooklyn-based Floating Point Collective. The project is powered by this Othermill-engraved circuit board and includes among other devices multiple 12-Key Capacitive Touch Sensor Breakouts by Adafruit – so yes, there will be lots of interaction going on at this installation!
Adafruit 12-Key Capacitive Touch Sensor Breakout – MPR121: The MPR121 has support for only I2C, which can be implemented with nearly any microcontroller. You can select one of 4 addresses with the ADDR pin, for a total of 48 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity. Read more.
