This project demonstrates how to use an RFID RC522 module with an Arduino to authenticate RFID cards. The system turns on a green LED if an authorized RFID card is scanned and turns on a red LED and ...

This repository includes the codes of my project on "Controlling Access using RFID & Arduino; Theft detection using Bluetooth Module & Arduino" In this rfid system I have used arduino uno, rfid reader ...

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

I am guessing that you have an Arduino Uno board handy. Even though most of the available libraries (for PN532) are focused primarily on Arduino Mega, I still prefer the Uno, as it’s more comfortable ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Meet the Arduino Compatible RFID Reader Module. It can hold card data for up to five cards, takes seconds to program, and holds card data in EEPROM memory, which means that the cards are saved ...

In this tutorial, you will learn about 433MHz ASK RF Transceiver Module and its interfacing with Arduino.
