Rfid door lock block diagram.
We ll start with explaining the underlying tech before walking through a tutorial of how you armed with little more than an arduino and some rfid tags and a sensor can implement your own door.
Each rfid card has a unique id embedded in it and a rfid reader is used to read the rfid card no.
Figure 5 shows the access control system block diagram using arduino and rfid.
Arduino uno is the brain of this project.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
