Arduino-RFID

Identify users using RFID cards. Similar to mifare-card-reader, but for arduino and with more stuff.

That's how it looks like:

What it does?

On starting, the LCD presents a "booting" message and then proceeds to display current temperature/humidity. Once a card is read, two things can happen:

• matches a known user: a "welcome" message is diplayed on the LCD and a green LED is activated for 3 seconds. Also, a relay is activated for a few seconds, which can be used to activate an electrict door lock;
• don't match any know user: a red LED is activated for 3 seconds, plus a "unknown" LCD message.

On the meanwhile the last known card uid read together with temperature/humidity can be requested to the device through HTTP.

TODO

• Have a server side app
  • associate cards with user's Facebook profiles
