RFID Door Lock Shield

Description

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 Jonathan’s 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:

• RFIDREAD-4100
• RFIDREAD-RW
• RFIDREAD-mRW
• RFIDRW-E-TTL
• ID12
• ID20
• RDM630
• RDM880
• HF MultiTag

Features

• Connections for RFID reader module
• Connections for status LED output

• Power pass-through jumper
• Reset button wired through to Arduino reset pin
• Blue “Arduino power” LED
