I am working on a project of an RFID system with fixe RFID readers. The readers are fixed to a gate of a warehouse to control the in/out tagged items. I have to install a tower light, with three colors, on the gate to tell if the tag is read or not.
We have a wired LAN connected to a back-office via wifi. the Ethernet shield Aduino Uno will be connected to the wired LAN. According to the state of the reader (The tag is read or not), the information will be transmitted from the back-office to the arduino to activate the tower light.
I am asking for your help with the code and the network architecture.
Note sure anyone will want to do your project for you if you don't want to work yourself... remember, this is YOUR project, usually people here give advice on how to solve specific challenges.
if you want to pay to get the job done, the Gigs and Collaboration forum is there for you.
PS: feels like a school project, so wondering why the timing is short.... how long did you wait before getting started? have you even started anything?
I can't comment on the network stuff, other than that I would set up the one controlling the tower light to act as a webserver, and have it react to requests by turning on or off lights, and have the one with the RFID reader make requests against it to communicate status.
If the tower light doesn't have mosfets to drive the lights builtin, you'd have to add those as well (I normally reach for a IRF3708 when I want a fet that is guaranteed to be able to handle most loads, can be switched easily, even by 3.3v, and is in an easy-to-solder TO-220 package.
For the tower light in my room (from my desk, I can't see either door, so i have sensors on the door so I know if my door is open, so I can make sure it's closed when I want privacy, and two of the other lights are made to flash if the refrigerator door is left open, because I often dont quite close it), I busted up the weird special light bulbs that wanted an inconvenient voltage, breaking up the glass until just the base was left, and I could mount, in it's place, a 12v led assembly (off the shelf), with its leads soldered to the contacts on on the bulb and held in place with polymorph (polycaprolacrone, aka friendly plastic, instamorph, etc - comes as pellets that become soft and pliable at the temperature of hot water). The bulbs only pull like 100mA, so I used a ULN2003 as the driver because they're cheap and I have tons of them kicking around....
this place has its own culture. we are all grinding away at our own projects. we will help a person who asks a question that indicates he is fully engaged in his project. we ignore at best, or snarl at, people who have not put forth effort
