Ultrasonic sensors are commonly used in Arduino projects for distance measurement. An ultrasonic sensor is a device that uses ultrasonic waves for distance measurement. It works on the principle of ...

In this project an obstacle detection system will be built with Arduino. This system mainly uses an ultrasound sensor and LED.When the ultrasonic sensor detects an obstacle at a distance < 3cm, ...

In this project, we will build Human Following Robot using Arduino and Ultrasonic Sensor. This robot can track and follow a person autonomously, making them useful in various scenarios like assistance ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

Since the project uses pretty basic components, the Arduino code is equally basic, too. It only has less than 50 lines and easily understandable functions and structures.
