This project is an object/person detection counter built with an Arduino Uno, an IR sensor, and a 16x2 LCD display. Whenever an object (e.g., a person walking past or a hand wave) interrupts the IR ...

This project demonstrates an Arduino-based LCD button counter using the Arduino UNO R4 WiFi and an I²C LCD display. The sketch counts button presses, debounces the input, toggles an LED, and displays ...

The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...
