/*
* This Arduino Code is to read and decode serial monitor
* code sent from USB to UART or USB to UART FTDI chip
* command sent from windows PowerShell or other systems commands.
* When the code is detected and matched with the present codes
* for example 6 is to Turn relay ON and 2 to turn OFF the relay
* in turn will turn ON AC bulb.
