This Max/MSP patch reads in a serial string like this:

Rnnn
Gnnn
Bnnn

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.

An Arduino program to send the appropriate data follows.

To use the patch, copy the text and paste it into a new max patch window.

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.

This patch receives an ASCII-encoded decimal string that ends with a linefeed and carriage return in the serial port, and converts it to a number. A Wiring/Arduino program to send data to it follows. It’s based on an example by Jamie Allen.

The following Max/MSP patch uses the netsend object to send data over a TCP socket. It sends three values. The Processing sketch further down is a server that receives the string that the Max patch sends and uses it to move a ball on the screen.

Hans Steiner, God of PD/USB and a darn nice guy, has released PDuino. In his words:

“Here’s the first test release of Pduino, a Pd firmware for Arduinoand a matching Pd object, [arduino]. This allows you get data from the digital and analog inputs, and send data to the PWM and digital outputs. It also allows you to change the digital pins from input, output, or PWM. And you can choose how many analog inputs and turn on/off digital input.

“Keep in mind its a test release, the only thing I am not sure about right now is digitalInput, everything else seems to work fine. In the future, I’d like to figure out how to add the pulseIn feature.

“This firmware would work well with Processing, Max/MSP, Flash, whatever. Then the Arduino becomes a dead simple, cheap sensor box for the newbies, but still open for playing later.”
