[Pcmofo] has shared a well-built, well-explained example of how to implement an RFID key system for a door. We call this the right way because it is well thought out and functional. In the past we’ve ...

There are many ways to lock a door. You could use a keypad, an RFID card, a fingerprint or retina scan, Wi-Fi, Bluetooth, the list goes on. You could even use a regular old metal key. But none of ...

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 ...

Electronic and Arduino enthusiasts searching for an Arduino project to keep them busy this weekend may be interested in a new Arduino Mega fingerprint door lock. Using a little Arduino programming the ...

Arduino enthusiasts may be interested in a new gesture controlled Arduino door lock which has been created by Adham Negm and uses an Arduino Uno together with a servo motor to slide the bolt back and ...

All they wanted to do was get into their campus apartment, and along the way they became online stars. Ziyan Zhou and Zachery Shivers, members of the Robotics Club at Rochester Institute of Technology ...
