RFID Door Lock Shield


This shield allows your Arduino to control a door lock using an electric strike plate and one of a number of commonly-available RFID modules, and is based on the circuit described in the "RFID Access Control System" project in the book "Practical Arduino".

Note: Does not include the RFID reader module itself. You need to purchase a module separately. We recommend Priority 1 Design as a good source of compatible modules.

Supported reader modules include:


  • Connections for RFID reader module
  • Connections for status LED output
  • Connections for manual strike release
  • Output to control 12V electric door strike
  • Power pass-through jumper
  • Reset button wired through to Arduino reset pin
  • Blue "Arduino power" LED
  • Green "External power" LED
  • Red "Strike plate activated" LED
  • Prototyping area
