Interfacing HC-SR04 Ultrasonic Distance Sensor with ATmega32 Microcontroller

Introduction

This project uses an ultrasonic sensor to indicate the distance of any object from it. Here we have made a setup based on a microcontroller in which real time distance is sensed by an ultrasonic sensor and displays measured distance on an LCD display.
