On the PC is running the processing application, obtained by integrating the “neorainbowduino_simple” example of the neorainbow-0.82 library, with the “Plasma” algorithm (taken from the examples of Processing: File -> Examples -> Topics -> Effects -> Plasma), which creates a 8×8 image.

This matrix of pixels is sent via serial port to the first of the two JeeNode’s on which runs a modified version of the Arduino firmware from the neorainbow-0.82 library.
This firmware variation allows the JeeNode ??to receive the bytes for the pixels’ RGB components in the image and send it via radio to the second JeeNode (using the RF12 library developed by JeeLabs, to easily use the RFM12B radio module).
The firmware on the second JeeNode allows it to receive the image from the first one, using the RF12 library, and send it to the Rainbowduino via I2C by the Wire library (included in the Arduino IDE).

Hardware components:
– A PC with Processing
– Two JeeNode
– A Rainbowduino
– An 8×8 RGB LED Matrix

Software/Firmware components:
– An application written in Processing (neorainbowduinoplasma.zip)
– The library neorainbow-0.82 which is composed of three parts:
A Rainbowduino firmware
An Arduino firmware
A Processing library
– The firmware for the two JeeNode’s (neoLed
tx.zip) (neoLed_rx.zip)
