Hi everyone
Yes, I'm very new to this and yes' I need some help.
Here's the hardware currently available:
-Arduino Uno R3
-Arduino GSM Shield
-Adafruit PN 532 RFID/NFC Shield
Here's what I would like to do:
Upon inital startup, a RFID card should be read. Once that is done, the exact ID of the card should be sent by the GSM shield using a text message to a remote number. Also included in that text should be the exact time when that card was swiped.
Questions:
First of all, is it possible to accomplish that using the Uno? Do I need to initialise the RFID shield first and the GSM shield only once the card has been swiped?
Layout: Uno at the bottom, GSM in the middle, RFID on top. I've been trying with some of the provided example codes. Problem is, if I only upload the "read Mifare" code it won't work when the GSM shield is connected. Even if I turn the GSM off manually it doesn't work. What's a possible cause for this?
And if I want to add some timing information to the text message I'd need some RTC module (DS1307)? Is that correct?
I've been searching the forum for answers and I know there's people with bigger problems, but as said before, I've never done anything like this. So all your help is highly appreciated.
Thanks in advance
Adrian
