This is very simple demo i recently made. I got this smart nfc ring as gift from my friend , he gave this because i will make some demo out of this.
I didn't disappoint him, and made this simple demonstration of controlling LED's via NFC Ring. Lets get into it.
This is smart ring R3F from JAKCOM. It has two NFC segments and some health monitor sensors too (Volcanic Magnet & FIR Energy). For information you can check out the JAKCOM site.
In our demo we are interested only interested on NFC part.The ring has two antennae for both NFC segment. Using the NXP NFC Tag writter android/ios app, set different values (string) for both segment.
Here it is the setup @embeddedclub
Boards are interfaced via I2C.
PIN_P10 - SDA
Reading the NFC ring data via NXP's NFC library and comparing the results (text) and turning ON/OFF corresponding LED's based ont he string values. for Quick demo check out here @embeddedclub
