Accelerometer data over bluetooth

Introduction

The story begins in one nice suuny morning when i came across project where the guy took a glove from some old nintendo console and remade it with accelerometer and bluetooth module. I watched his youtube movie without even breathing. A few months later came the time when it was necessary to pick up a bachelors project so i can get a degree. Searching for a right topic for me i came along "Data transmission over bluetooth" topic and i said myself, "this would be great to use bachelors project to make something i want". And that's, how it began :)

Schematic

As you can see, i chosed the Atmega8 microprocessor. The reason was that i was playing a little bit with it before starting bachelors project, so i used my little base knowledge i already gained ;) What the Atmega does is that it reads and converts axes from accelerometer and send then over UART into bluetooth module.
