This project demonstrates the interfacing of Accelerometer (ADXL335) with Arduino and calibrating it to measure Angle from a reference plane. Also measuring the distance from object in its line of sight. The sensor data is fed to Arduino (Analog Input), it is processed and then the values are displayed on and 16×2 LCD.ADXL335 is 3-axis accelerometer with analog output from Analog Devices. ADXL335 acceleration measurement range is +/- 3 g. The Voltage requirement of IC-ADXL335 is typically 3.3V, but the module has on board regulator, which facilitates connection of 5V supply to it. It is extremely Low-Power device.  

The main aim of this project is to understand that how Seven Segment Interfacing is done using Arduino. The project idea is to make an application based on Seven Segment Display. Here we demonstrate Seven Segment Interfacing and its application in a single project. Applications are Seven Segment Counter and Ultrasonic Sensor & Seven Segment based Distance Measurement project.
