Accelerometer Interfacing with AVR
The article covers how to interface an accelerometer with the atmega32/atmega16. Before proceeding, the user must know the basics of ADC (Analogy to digital converter) of the AVR. An accelerometer is an electromechanical device that measures acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic – caused by moving or vibrating the accelerometer. Accelerometers are of two types Analog and Digital. In this post, we will be discussing Analog accelerometers. They give voltage as output which is proportional to acceleration. The digital one gives the PWM output or direct binary digital data
