This package includes a Pd object and a matching Arduino firmware. It allows you to control the Arduino board from Pd without having to program in Arduino's C++. To use it, first download and install Arduino 0018 or newer from http://arduino.cc. When you run the Arduino program, then you'll be able to choose firmware from Arduino application, in the menu: File -> Open -> Examples -> Library-Firmata Once you have uploaded a firmware to your Arduino board, open up arduino-test.pd in Pd, then choose your serial port with the [open( message. * for more on Arduino, go to: http://arduino.cc * for more information about this firmware here: http://firmata.org WARNING! This version of the arduino object for Pd will only work with 2.1 versions of Firmata. It will not work with older versions of the firmware! (You can also optionally unzip the included Firmata-2.1 firmware and follow the README included in there.) Hans-Christoph Steiner
