Hardware system consist of basically 3 components named as Arduino, servo-motor, and ultra-sonic sensor. Ultrasonic sensor is mounded upon a servo motor which helps it to move and provide it a turning ...

Arduino Ultrasonic Distance Arduino (HC-SR04) Ultrasonic Sensor displays the distance on the (1602) LCD Module in cm.

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 ...

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 ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...
