“Hello everyone, This is my first instructable and was presented by Judhi Prasetyo. The workshop was hosted by Assembly , where I am working as an intern and its one of the best place to work if you are a maker.
Coming back to the RFID lock system, I will explain to you how it works.
Overview:-
We use RFID tag and reader in this system.Now every tag has a unique codewhen you place the tag on the reader which is connected to ArduinoThe reader decodes the radio frequency code to multiple characters and sends it to ArduinoArduino already has stored RF code in its memory which is written by usArduino checks if the RF code received matched to the code in its memoryIf it matches then servomotor opens the lock with rack and pinion mechanism that converts rotation motion to linear motion”
