Distance Meter Using Arduino

The purpose of this project was to aware students of engineering about the working and application of the Arduino and sensors. These instrumentational tools play a vital role in construction of integrated and complex real-life systems. We used ultrasonic sensor along with a microprocessor (Arduino) to measure distance of the object in range of the particular sensor. We coded our microprocessor to work for the particular application. As a result, we were able to measure critical distance which as an application will be used a sparking warning device. Nowadays, we have some difficulties in obtaining the distance that we want to measure. Even though, measuring tape is an easy option, but this kind of amount of time taken for a pulse of sound travel to a particular surface and return as the reflected echo. After that, the circuit that have been programmed with AT mega microcontroller will calculate the distance based on the speed of sound at 25°Cwhichanambient temperature and also the time taken. The distance then will be display on a LCD module.
