From the project
An AVR based door access controller for wiegand readers
This project is about building an open source physical access control system for small communities and groups.
In this directory you will find the hardware design (schematics and PCB) for a two door controller using an Arduino Nano. Its main features are:
Can be powered with 12V or 24V. Support various setup for the door lock, the relay can be connected to 12V, 24V or GND as normally open or as normally closed. An USB power supply to power additional devices such as an AP for network connectivity. Use RJ-45 connectors for the doors to allow standardizing the physical installation.
