How to make Distance Meter using HC-SR04 Ultrasonic Sensor and Arduino Uno
0 Comments
In this project we’ll see how to make a distance meter using Ultrasonic sensor and Arduino Uno. It’s a very simple project that even a beginner would enjoy making. The distance meter measures the distance between the ultrasonic sensor and the obstacle placed in front of it. Let’s have fun understanding and building this...
Interfacing Ultrasonic Sensor HC-SR04 with Arduino

The Ultrasonic Sensor Module works by using sound waves to figure out how far an object is. The module uses two transducers: one transmits out a high-pitched sound, and the other receives the sound signal bouncing back from the object. These sensors are cheap, easy to use, and don't need much power to operate....
Distance Measuring with LED Notifier using HC-SR04 Ultrasonic Sensor and Arduino

In this tutorial, we are going to learn how to use ultrasonic sensor HC-SR04 interfacing with Arduino and measure the distance which will be notified by 7 LEDs. As we move closer to the sensor the LED will glow consecutively and vice-versa. HC-SR04 Ultrasonic Sensor Pinout The sensor has 4 pins. 5volts is...
