Small issue the Arduino sketch makes use of Arduino pins 2 3 for Rx Tx, respectively using SoftwareSerial, but your description. If you havent solved it yet, you might be in luck I just wrote and released released minutes ago, I saved a link to this post an Arduino library for the 24XX1025.

Arduino code for IMU Guide algorithm. Using a 5. DOF IMU accelerometer and gyroscope combo Starlino Electronics. This article introduces an  implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5. DOF IMU unit from Gadget. Gangster AccGyro. The theory behind this algorithm was first introduced in my Imu Guide article. The AccGyro is mounted on a regular proto shield on top of an Arduino Duemilanove board. Parts needed to complete the project Arduino Duemilanove or similar Arduino platform AccGyro IMU board Protoshield optional Breadboard Hook up wire 2. AWGThe hook up diagram is as follows AccGyro lt   Arduino. V          lt   5. V  GND      lt   GNDAX       lt   AN0. AY       lt   AN1. AZ       lt   AN2. GX4      lt   AN3  GY4      lt   AN4  Once you have completed the hardware part, load the following sketch to your Arduino. Run the project and make sure you are receiving an output on your serial terminal you can start the terminal from your Arduino IDE. To analyze the data I have developed a small utility called Serial. Chart. It is open source so feel free to customize it for your own needs. Here is the output from Serial. Chart software The test was performed as follows first I was tilting the board slowly marked smooth tilting on the screenshot next I continued tilting the board, but I also started applying some vibration by tapping the board quickly with my finger marked Titlting with vibration noiseAs you can see from the chart the filtered  signal red line  is indeed more immune to noise than the accelerometer readings alone blue line. The filtered signal was obtained by combining the Accelerometer and Gyroscope data. Gyroscope data is important, because if you would simply average the Accelerometer data you would get a delayed signal. Given the simplicity of the code and of the algorithm I am satisfied with the results. One feature that I would like to add is compensation for the drift effect that you might encounter with some gyroscopes. However the AccGyro board proved to be very stable in this respect, since it has built in high pass filters. If youd like to experiment on your own, I recommended first reproducing this testing setup ,  then shift slowly towards your application needs. For example you may take the C code and port it to PICs C1. C3. 0 or AVR GCC it shouldnt be too dificult. Below are some useful resources and their descriptions. Serial. Chart executables can be downloaded from here Serial. Chart0. 1. Once you start Serial. Chart application you will need to load the imuarduino. In this configuration file make sure to update the port settings to Arduinos COM port. On my computer Arduino was detected on COM3, on yours it might be different. For more information on configuration file syntax see http code. Configuration. File. Syntax. You can also download and compile Serial. Atm Pin Number Cracking Program Download. Chart from Google Code http code. You will need a SVN client to checkout the code I use Rapid. SVN for Windows. Serial. Chart was developed using  Qt SDK from Nokia http qt. UPDATE 2. 01. 0 0. Many people ask me what about the other 2 axis, here is the code that outputs 3 axis, including the Serial. Chart configuration script. ImuArduino3axisoutput2. I also removed some overhead code that Alex pointed out in the comments, this reduced the interval between samples. In the example below I rotate the board around the X axisblue which is parallel to the ground. I do it by hand so X is not exactly 0, but close. The axes that change are Yred and Zgreen. Please note the relationship X2Y2Z2 1. The dashed  cyan, magenta and lime lines are unfiltered signals coming from accelerometer alone Rw.
