An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

One uses the LiquidCrystal_I2C library (I²C display). The other uses the LiquidCrystal library (parallel display). In the code, set: USE_I2C = 1 for I²C displays (with LiquidCrystal_I2C) USE_I2C = 0 ...

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 ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...
