Ultrasonic sensor powered by Arduino UNO The servos should not be powered by the Arduino directly due to insufficient current supply, which could damage the voltage regulator. Instead, an external ...

One of the common applications of ultrasonic sensors is parking assistance systems of automobiles by using an Arduino UNO board, HC-SR04 sensors, RGB LEDs and Buzzers. Assume that four distance ...

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.

This IoT-based smart bin project integrates an Arduino Uno R4 WiFi with ultrasonic sensors and a servo motor to automate waste disposal. The system uses proximity detection to open the lid and ...

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 ...

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 ...
