This Max\/MSP patch reads in a serial string like this:<\/p>\n

Rnnn
\nGnnn
\nBnnn<\/code><\/p>\n

Where nnn is an ASCII-formatted decimal number from 0 to 255. It then converts the values into the RGB colod for the patch’s background.<\/p>\n

An Arduino program to send the appropriate data follows.<\/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
