Arduino code for simplified Kalman filter. Using a 5DOF IMU (accelerometer and gyroscope combo)

[starlino]

This article introduces an implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5DOF IMU unit from GadgetGangster - Acc_Gyro . The theory behind this algorithm was first introduced in my Imu Guide article.

Parts needed to complete the project:

- Arduino Duemilanove (or similar Arduino platform)
- Acc_Gyro 5DOF IMU board
- Protoshield (optional)
- Breadboard
- Hook-up wire 22AWG

The hook-up diagram is as follows:

Acc_Gyro <---> Arduino
5V <---> 5V
GND <---> GND
AX <---> AN0
AY <---> AN1
AZ <---> AN2
GX4 <---> AN3
GY4 <---> AN4

Test results show algorithm is really eliminating some noise:

Well Done

I like what you have done and i am very interested in the data collection and chart. ( exactly what i am trying to do at the moment with a IR sensor)

Do you mind if i ask
Do you mind if i throw some questions your way i might need some help as i am only knew at this. greatly appreciated.
