This project is targeted to measure vibrations of remote-controlled helicopters. The acceleration sensor I use is a Bosch BMA020, quite old, but it should fit my needs.
The microcontroller is an Arduino micro. I connected the BMA020 to 3.3V from the Arduino, sensor data is transmitted via I2C on digital ports 2 and 3 of the Arduino.
