Story

This project demonstrates the controlling of an RGB LED by reading NFC tags via NFC reader (PN1720). LPC824 Xpresso board is interfaced with PN1720 controller via I2C Interface.

NFC coins are pre programmed with texts field "RED," "BLUE," "GREEN" and "WHITE."

The LPC824 Xpresso board comes with RGB LED, which is going to be controlled via NFG tags. PN1720 can operate in read or write mode for this demo by default its configured to read mode.

Flashing the NFC coins on the reader antenna (2cm maximum) will change the color of RGB based on the text which written on the Tag.
