The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project measures the distance of an object using an HC-SR04 Ultrasonic Sensor and displays the result on a 16x2 I2C LCD. 📷 Demo (What It Does) Sends ultrasonic pulses from the sensor. Calculates ...

This bot is controlled by an Android app which sends commands via Bluetooth. Servo motors control a three-axis robotic arm to perform pick-and-place operations. The project simulates a basic robotic ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...
