+// Function to get current state (high\low) of a digital pin on AVR

+// Calling Sequence

+//
+// Parameters
+//     port : port of microcontroller to be used (1 for PORTA, 2 for PORTB,...)
+//     pin : pin of port (mentioned above) to be used
+//   Returns->  
+//     state : state of the pin (0 for low and 1 for high)
+//
+// Description
+//     Each AVR microcontroller has pins which can be configured as digital

+//     User has to select one of these port and which pin of that port is to
