Using a 5DOF IMU (accelerometer and gyroscope combo) - This article introduces an implementation of a simplified filtering algorithm that was inspired by Kalman filter.. In this article we will learn how the MEMS accelerometer, gyroscope and magnetometer work and how to use them with the Arduino Board. Also with the Processing IDE we will make some practical applications using the sensors. iPhone 4 - Wikipedia - The iPhone 4 is a smartphone that was designed and marketed by Apple Inc.
