 ===== General Idea =====
-The idea I had was to use the tech nails for playing musical notes on an speaker and thinking that people that hear me won't know what notes I am playing I added some leds to show which musical note was played.

 ===== Working with RFID =====
-I worked with the PN532 breakout board and three RFID tags. The board came without pins soldered, so I had to soldered them. So once I soldered them, I made some connection for communicating the board with an arduino uno.

 The communication on the board is specified on its chip selectors SEL0 and SEL1 and since I planned to use the SPI protocol for communication, I needed to to put a jumper in ON position on SEL1 and another jumper in OFF position on SEL0.

+Since the Arduino works with 5 volts and the PN532 board with 3.3v, I had to connect a buffer that lowered the voltage of the arduino to 3.3v, so that it did not burn the PN532 board. The buffer I used was the IC4050.

 ===== Making an Interactive Circuit =====
-For making the circuit I wanted, I had to add three leds to the outputs of the arduino and an speaker. So, I had to solder some cables to the speaker and then added it to the output of the arduino.
-Both the speaker and the leds can not be directly connected to the arduino sice they have very low resistance and that means a high current can pass through them which could burn the arduino pins. So for limiting the amount of current at the output of each led and the speaker I added a resistance in series to the speaker and since only one of the leds was going to be on when a note was played I added only one resistance in series for the three leds.

-===== Hiding the RFID Tags Inside the Fake Nails=====
 For hiding the RFID tags in the faik nails I did the following:
   - I took one of the faik nails and added a layer of base coat to the inner side of the nail and waited until it dried (this was done to better the adhesion of the RFID to the nail).
   - Then, I putted the RFID tag over the dried layer of base coat.

   - I did the steps 1 to 4 for the other two nails.

+For working with the Pn532 board, I downloaded a library provided by ardafruit, which can be downloaded from [[https://github.com/adafruit/Adafruit-PN532|here]]. Since I have never worked RFID, I opened the example "read Mifare" provided on the library and started to work from there. I realized that for what i wanted to do I just needed to read the UID of the RFID tags, so I erased almost all the code of the example and kept just the parts that were necessary for reading the UID. {{  :fabricademy2017:students:luis.dulanto:w12p1.png  }}
