When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects ...

The Arduino board reads the data from the RFID reader, which in turn drives the relays through ULN IC for that particular quantity. Note: At the end of the article we have added the complete video ...

The RC522 RFID reader module makes Arduino RFID integration straightforward, supporting reading, writing, and authentication operations that we'll explore in this tutorial. After mastering these ...

In this tutorial, the presenter will be giving you a tutorial on radio-frequency identification (RFID), how it works and how to make an Arduino based RFID door lock. It’s a non-contact technology that ...

You’ve probably heard about RFID and what it can do, but there are different types of RFID systems that are appropriate for different applications. This session will explain some of the basic concepts ...

MFRC522 device: typical chinese clone. My problem here is that the arduino sketch is not recognizing the library, it gives errors like this: 'Class MFRC522' has no member named 'PCD_Init' The only way ...

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 ...

While setting an alarm is easy enough, but this Arduino-powered alert system will just send you a text when it's time to grab your clothes. Instructables user MakerBee's alert system uses an ...
