Registering accelerometer data may be useful in many areas like rocketry, vehicle, or in sports. For this as usually you need an accelerometer, microcontroller and memory where to store data. In this project there is a x axis Freescale MMA2201D accelerometer used that has a ±40g sensitivity. All readings and interfacing is done by Motorola microcontroller HC908QT4. Data is written to 25LC640 EEPROM chip.
Working with devices is easy – open jumper to enter measurement mode and close to start transfer memory contents to PC via serial interface. When you have data in computer it is up to you what to do then – so why not to start with simple graphs in excel?
