//This code uses:
// LiquidCrystal_I2C and Wire library.
// Pins 14 and 15 as SDA and SCL.
// Pin 31 for Serial communication at 9600 bauds
// Pin 5 for tone speaker output
// 5 Volts for RFID Tag reader board
// 3.3 Volts for Speaker and LCD display.
// Communcation protocols: i2c for display and Serial at "Serial1 interface" for RFID tag reader.
// This code makes the i2c display blink its backlight for 1 second and writes "hello" during setup and "world" during loop.
