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 16x2 LCD.

Required Components:

 

Arduino

ADXL335 Accelerometer

HCSR04 Ultrasonic Module

16x2 LCD

Pushbutton

10 kOhm Potentiometer
