I'm new on this forum so I will introduce myself for a bit. I'm Justin, 16 years old and from Holland. I have been busy with Arduino a few months now and because I'm in my last year of secondary school, I have to write a Final Assignment.
For this, I have choosen the subject 'NFC and RFID'. I did this because this technology really grabs my interests. As an addition to my text-based Final Assignment, I would like to make an NFC-device. Here starts the trouble.
I bought an NFC shield for my Arduino, some tags and started building. Clicking the shield on top of the arduino, download the PN532-library and loaded an example project (readMifareTargetID.PDE). After this, I clickec on the upload button inside the Arduino software. I got the following error - even though I installed the library correctly:
I don't understand what's going wrong.
I use an Arduino Uno R3 with this shield: http://www.seeedstudio.com/wiki/NFC_Shield I really hope someone can help me, I don't know what to do right know and I'm really stuck with my whole project.
