This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the ...

Vehicle Detection: Ultrasonic sensors monitor each parking slot and send data to the Arduino Uno. Slot Availability Display: Real-time updates shown on an LCD using I2C communication. Barrier Control: ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
