This Max\/MSP patch turns on or off an LED attached to an Arduino. Max and the Arduino communicate serially.<\/p>\n
To use the patch, copy the text and paste it into a new max patch window.<\/p>\n
Thanks to David Mellis and Jamie Allen for the collaboration. These patches were written for a one-day Arduino workshop at NIME 07 hosted by the three of us. The Arduino program comes from the Arduino example files, by David Mellis.<\/p>\n
