This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

This repository contains Arduino code and documentation for interfacing with an I2C (Inter-Integrated Circuit) LCD (Liquid Crystal Display). The code is designed to facilitate easy integration of I2C ...

After acquiring Philadelphia-based Neiman Group, Boston ad agency Allen & Gerritsen found itself with two teams of employees separated by 300 miles. It presented an increasingly common problem: When ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
