A door lock system that can operate by scanning OSU ID cards or receive an input from a keypad (OSU ID numbers). The allowed ID numbers are on a whitelist while any other ID will be denied. The system can be powered off by either a wall outlet or an Ethernet cable and both will be providing the system with 12 volts DC The server saves the access log records and they include: access time, ID number and entry approval/denial. This project is designed for the OSU Amateur Radio Club in Snell Hall.

Name Description
Motherboard This is the schematic of the motherboard, which utilizes an Arduino Uno as the microcontroller. It also has DIP switches that allow easy selection of settings between which daughterboard it will be powered by   Download
POE Daughterboard This is the schematic of the Power-Over-Ethernet daughterboard, it will take input from a POE Injector which provides 48Vdc and it will output 12Vdc along with data transmission. Daughterboard can handle up to 57Vdc input   Download
120 to 12 Daughterboard This is the schematic for the 120Vac to 12Vdc daughterboard. It will provide the same power output to the motherboard but it will take in an input of 120Vac which is the standard wall outlet power in the U.S. While this is a custom PCB, it only consists of connectors and the component used is CUI INC's PSK-S5B-12 which will convert the 120Vac to 120Vdc and then lower it to 12Vdc.   Download
Server This file is used to read encrypted data packets over a TCP connection with the motherboard. It also stores the time when an ID attempts to access the lock connected to the server.   Download
