I am involved in a project that is creating a RFID reader that talkes to a database, confirming if a person has purchased a ticket for a particular event. To this point I have got everything working except for the part where the the HTTP GET response is sent back to the Arduino.
A "#1" is sent back to the Ardiuno if the person has purchased a ticket and a "#0" is if they haven't.
~I need to parse the incoming HTTP data to determine if a #1 or #0 is sent back and then light up a LED accordingly. How can I do this???
