Hello,
I am trying to do a similar thing to what is going on here. I need to connect an Arduino to phpMyAdmin databases. Im trying to set up an RFID system where the Arduino reads a tag, then it is sent to the database on phpMyAdmin to be matched with a name. This name then is printed on a website. This needs to happen a few times a second as multiple tags could pass the scanner at one time. I have the RFID shield (Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras : ID 789 : $39.95 : Adafruit Industries, Unique & fun DIY electronics and kits) but am unsure how to go about this. Any help will be much appreciated, thanks!
