•An Ultrasonic sensor and a 16X2 LCD display were interfaced using Arduino Uno R3 Microcontroller to measure the distance from the sensor to an obstacle placed in front of it.•The LiquidCrystal.h ...

This project implements a real-time distance measurement system using an Arduino Uno microcontroller and an HC-SR04 ultrasonic sensor. The measured distance is displayed on an I2C LCD screen, ...

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.
