Building a human-following robot using Arduino and three ultrasonic sensors is an interesting project. What makes this project particularly interesting is the use of not just one, but three ultrasonic ...

The Ultrasonic Sensor Based Arduino Car is an autonomous vehicle that uses ultrasonic sensors to detect obstacles and stop or navigate around them. This type of car is a popular project for robotics ...

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.

A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of this ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.
