Hi guys
I'm completely new to Arduino and it's technology so sorry if this would be a stupid question.
The thing I wanna do is with an Arduino RFID system, navigate through a website.
So my question is how can I send the data of an RFID tag to a PHP script that is connected to a database? Do I need an Ethernet Shield for this or not?
thx
Yes, you need an ethernet shield or an other ethernet modul (i.e. XPort) to call the php script over the internal network or the internet. The php script itself has to be placed on a webserver.
see also this thread here:
oke thx for the reply Webmeister, but I don't wanna buy an ethernet shield...
Is it possible to build an external Processing application which receive the data from Arduino and which receive webcontent via webservices. All this whitout an ethernet shield?
If this is possible do I need an extra program/script for making the bridge between Arduino and Processing?
thx
Are you talking about connecting the arduino to a pc? The arduino will need to be connected to something that connect to the website you mention.
Yeah it is connected to the PC with a usb cable
It appears that when the arduino has information to send, it will need to put the info in the serial input buffer on the computer to which it is attached. There will need to be a program running on the computer to collect the data in the serial input buffer and send it to the desired web server.
can it be done by using normal arduino wishield 1.0 ?
can the php send data from db to the arduino?
OMBAK did you manage to get the answer? I am also looking for a place where I can read how to send information from php to the arduino with an ethernet shield....anyone?
I try to do some experiment with php & Arduino, here http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1294328082 is the writing code from php to Arduino by serproxy. It's work and you can read with fget function, but i'm trying to create a function for read. In theory it's simple, you need an end charater of Arduino's string and you store in an array the serial message until don't find an other end char.
I hope this can be useful

Hey Mauro I dont know what you mean. Perhaps I misunderstood you. The way I am interfacing arduino and a server is through an ethernet shield that connects to a website.
Hi Efrain, i was answering to Cosmo because he tell that he don't want buy an ethshield.
I done the same because i don't use Eth
Sorry for trouble, but youre question it's intresting and the wishield seem like very useful.
in http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1294937433 this post use for purpose php+mysql ethshield.
Bye
