• Shield to allow Arduino to control a door lock
• Provides easy connection of external RFID reader module to Arduino
• Power pass-through jumper
• Reset button wired through to Arduino reset pin

The Arduino RFID Door Lock 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".

Connections:

• Manual strike release connection
• Status LED connection
• RFID reader connection

LEDs:

• Power LED: Indicates that 5V is present on the Arduino
• 12V in LED: Shows that an external power source is connected
• 12V out LED: Shows that the door strike output is activated
