![]() Arduino Ultrasonic Sensor Circuit Diagram: As the HC-SR04 needs 5v so this Ultrasonic Sensor can be powered using the Arduino’s 5v. Ranging Distance : 2cm – 400 cm/1″ – 13ftĪs you can see in the Picture above, the HC-SR04 has a total of 4 male headers which are clearly labeled with Vcc, Trig, Echo and GND. I would appreciate your support in this way! I may make a commission if you buy the components through these links. Ultrasonic Sensor Arduino Programming and finally.Ultrasonic Sensor interfacing with Arduino.For the Step by Step explanation, you can watch a video tutorial given at the end of this Article. ![]() The same programming can also be used in the Robot for detecting any Obstacle, or it can be used in a security project, or the same idea can also be used in making the touch-less doorbell system. The Obstacle detection range can be adjusted in the programming. This LED will be controlled as per the pre-defined value. For the demonstration purposes, I will use an Led which will be controlled depending on the distance of the object from the HC-SR04 Sensor. Ultrasonic Sensor HC-SR04 Interfacing with Arduino:Īrduino Ultrasonic Sensor Project Obstacle detection using Arduino– In this tutorial, you will learn how to use the HC-SR04 ultrasonic sensor with Arduino for Obstacle detection and distance measurement.Arduino Ultrasonic Sensor Circuit Diagram:.Arduino Ultrasonic Sensor, Description:.
