I2C injection with the Bus Pirate

I decided to create a simple lab involving an Arduino Uno, in this case a SparkFun RedBoard, and a BlinkM LED that can be controlled over I2C. The Arduino would have a simple sketch that will update the color of the BlinkM and using a Bus Pirate I would then sniff traffic that is occurring between the BlinkM and the Arduino. I would also like to study the process involved in using the Bus Pirate to inject messages to take control of the BlinkM and have it change to a different color. I’m not blowing anyone’s skirt up with this, but I gotta start out somewhere.

Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.

Check out the video after the break.
