Hardware Specs
- Electric door strike (12V, 250 mA), will be wired fail secure, i.e. applying electric current to the strike will cause it to unlock
- RFID/NFC card reader (MiFare cards), purchased this [one]http://www.ebay.com/itm/PN532-NFC-RFID-Controller-Reader-Writer-Kit-For-Arduino-UNO-Mega-2560-R3-A124-/271186702139?pt=LH_DefaultDomain_0&hash=item3f23fcaf3b
- card reader can communicate via I2C/Uart/SPI
- two status LED's
- interposing circuit for door strike/RPI
Outdoor enclosure to hold card reader: [Tom fill in here]
- will hold card reader
- "Power" LED, red LED that will be on continuously if there is power
- "Status" LED, green LED that will blink a sequence with succesful card read, also blink a different sequence if failed authentication
RaspberryPi:
- GPIO list:
- status LED's
- door latch interposing circuit
- door latch buzzer (let the user know the solenoid has been energized)
- door reed switch (door status)
Software Roadmap
- Version 1.0
