In this tutorial I will be showing you how to make a NFC detector. It's very easy.
Step 1: Parts
All you will need is :
-wire (any decent length)
-NFC Enabled device
Step 2: Making the Coil
Just wrap the wire in a coil around your 4 fingers (I'm 14 so try 3 fingers if your older). Leave the first and last bit of the wire out. You don't need as much as I used but oh well.
Step 3: Tape It Down
Tape the top part so it doesn't fall apart. Pretty simple.
Step 4: Strip the Ends
Strip the ends of the wire, I used solid wire but ANY thin wire will work :)
Step 5: Bend the Wires
Bend the ends of the wire in so its easier to attach the LED. (You don't have to if your using clips or soldering)
Step 6: Attach the Led
Just put the LED in the bent bits and it is FINISHED! (This can get very annoying)
Step 7: Turn on NFC
Turn on NFC on your phone. Simple.
Step 8: ITS TIME
Place your phone on top! DONE WOW OMG POWER I'm not kidding you, this works!
