Hi guys! I am new in Arduino and I want to start the project. I need your recommendations.
What do I need in my system?
I need door lock control system with Ethernet and RFID. System will work like following:
People have cards. Any guy put the card at the RFID element and Arduino connect to HTTP-server via Ethernet! HTTP-server find record with ID of this card... and get back respond with code "YES" or "NO". Arduino open the lock of door if code is "OK" and do nothing else!
So! Friends, tell me please, what hardware you recommend me to do all that I said above.
What I think. 1) The Arduino Duemilanove ("2009") (~ 45$) [or Russian analog «Cosmo Black Star» (33$)] 2) Arduino Ethernet Shield (~40$) [or other?] 3) RFID-reader ( ~??? ) Which do you recommend... and how much it cost? 4) Wires and plate to connect all wires (or can I connect all without plastic plate?)
I must to do this system, and I want to know what must I buy and how much it will cost.
This system will be on many doors ( about 100 doors) and cost play big role!
Thanks for help.
