Visualizing L3G4200D gyro movement with Blender and Python

Visualization using blender and python on the SW side and on the HW side I used an Arduino to deliver the raw data from the gyro.

I have purchased a rather cheap gyro L3G4200D sensor that can detect 3 axis rotation and deliver it through an I2C or SPI interface. Visualizing the gyro turned out quite difficult as I could not see what the Gyro was outputting only the raw data. I needed a visualization. I ended up writing a python script that used Blender to visualize the gyro that is connected to an Arduino Uno. With this combination, I got a real-time report that proved the sensor to be quite accurate at what it does.

Works on any microcontroller capable of I2C or SPI
Supports all 3-Axis
