Arduino Tutorial for Beginners 16 - RFID Tutorial RC522 with Arduino Uno

Welcome to this video on Arduino Tutorial for Beginners. This video about RFID module. So we will see How to use Arduino and RFID.
This video shows how to use RFID module, and check RFID card to turn LED on/off

RFID MODULE PINS ARDUINO PINS
* RST/Reset RST 9
* SPI SS SDA(SS) 10
* SPI MOSI MOSI 11
* SPI MISO MISO 12
* SPI SCK SCK 13
RFID Library : https://github.com/miguelbalboa/rfid
Convert HEX to Decimal : https://www.branah.com/ascii-converter

Code to turn led on/off:

Create a empty string
String _yourString = "";

put _yourString += buffer[i]; in the function as the video

if( _yourString == "This is Decimal RF card number ")
turn led on;
else turn led off;

Arduino is an open-source hardware platform based on an Atmel AVR 8-bit microcontroller and a C++ based IDE. Arduino is the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. Arduino microcontrollers are programmed using the Arduino IDE (Integrated Development Environment). Arduino IDE Can be downloaded for free from http://arduino.cc/en/Main/Software
Arduino programs, called “sketches”, are written in a programming language similar to C and C++. Many sensors and other hardware devices come with prewritten software – look on-line for sample code, libraries (of functions), and tutorials. Learn the Arduino platform and programming language to create robots, interactive art displays, electronic gadgets and much more.
