Arduino UNO + MPU-6050 + Processing
I recently bought a GY-521 MPU-6050 sensor. The InvenSense MPU-6050 sensor contains a MEMS (Microelectromechanical systems) accelerometer and a MEMS gyro in a single chip. This sensor contains both a 3-Axis Gyroscope and a 3-Axis Accelerometer allowing measurements of both independently, but all based around the same axes.
