In this article, we will explore in detail how to build a human-following robot using Arduino and three ultrasonic sensors. Also check all the Arduino based Robotics projects by following the link.

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

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 design was prototyped using an Arduino, which controlled an LED through feedback from an ultrasonic proximity sensor. The LED would flash into the user’s peripheral vision, glowing when the sensor ...

Producing items onto a screen simply by touching the air is a marvelous thing. One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a ...

If you're just starting out with Arduino, you might be wondering what projects you can take on to practice your skills. Don’t worry we got you covered. We have created this massive list of 37 beginner ...

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...
