3-Axis Accelerometer Interfacing with ATMEGA16

In this project, the interfacing of a 3-axis accelerometer sensor FXLN8361 with AVR ATmega16 microcontroller is essentially discussed. Here, we will measure the tilt of the accelerometer sensor or the material to which the accelerometer sensor is attached and we will display the three outputs of accelerometer sensor in a 16X2 alphanumeric LCD. But, the three outputs of 3-axis accelerometer sensor are analog in nature and microcontroller cannot process the analog signal directly. So, first it will convert the three analog outputs of ADXL335 accelerometer sensor to digital values using its analog to digital converter and then it will display the three converted digital values in the 16X2 alphanumeric LCD. Now, we will tilt the accelerometer sensor or the material to which the sensor is attached in different direction and we will see the changes in its output values in the 16x2 alphanumeric LCD.

This accelerometer measures static acceleration of gravity in tilt-sensing application, as well as dynamic acceleration resulting from motion, shock, or vibration. The accelerometer sensor is used in mobile devices, gaming systems, disk drive protection, image stabilization, sports devices, health devices and etc.
