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 microcontroller in which real time distance is sensed by an ultrasonic sensor and microcontroller displays measured distance on LCD display. Required ComponentsATmega 32 Microcontroller HC-SR04 Ultrasonic Distance Sensor 16×2 LCD Display 5V Power SupplyHardware Ultrasonic Distance Locator – Block Diagram Circuit Diagram Ultrasonic Distance Measurer – Circuit Diagram Circuit Description The overall circuit assembled on the breadboard contains three major components :ATmega 32 Microcontroller, Ultrasonic [...]
