Accelerometer is a very usefull sensor for detecting movement. In this project I use simply settings LSM303D sensor and LCD PCD8544 display. In this settings I choose BluePill board – STM32F103C8T6 microprocessor
If you use this project in professional device, you must now, about gravity earth and acceleration of gravity, and must implement Kalman filter in software.
