  Screenshot of simulation

RedBullSimulator is an empty can of Red Bull with an AltIMU-10 v4 Gyroscope tucked inside. This device serially communicates the accelerometer/gyro measurements to an Arduino Uno via I2C. This data is captured by the Processing IDE (through USB) which interprets the data and displays a live simulation of the Red Bull's orientation in space (with textures and everything).

I was inspired to work on this project while I was trying to teach myself serial communication and interfacing the Arduino with the AltIMU sensor. At the time, I had already finished two energy drinks and it only seemed natural to work with what I had: an Arduino, empty cans and a sensor.
