arduino based distance sensor using arduino

Here  is a simple tutorial to build a Distance sensor which will show the distance from the distance sensor HC-SR04 ( Or any other compatible devices) to the wall or obstacles in front of the sensor in CentiMeters. This project uses a HCR-SR04 distance sensor and atmega 328 or any other atmega chip which is programmed using a arduino programming kit, SO the project is based on arduino. But our final Circuit ...
