In this project, we measure distance using HC-SR04 Ultrasonic sensor. First, we used the Ultrasonic Sensor as is, to calculate the distance of an object in front of it. It returns a float which ...

Visualizing the environment with an ultrasonic sensor by gathering points that form a 3D point cloud using Arduino. This project aims to visualize real-time data from an ultrasonic sensor mounted on ...

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.

If you are just learning how to do Arduino projects or want to start, ... with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer.

By utilizing ultrasonic sensors, this project allows beginners to learn how to build a car that can detect obstacles and maneuver around them independently. It serves as an excellent introduction to ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...
