Morse loop()

void loop()
{
	while(!Serial.available());
//This command makes it wait until the Serial data is sent
	while(Serial.available())
	{
		Input[Index]=Serial.read();
//Stores the byte of data from the serial buffer
		Serial.print(Input[Index]);
//Prints out the same data
		if(Input[Index]>=97&&Input[Index]<=122)
		{
			Input[Index]=char(int(Input[Index])-32);
//Changes lowercase letters to uppercase
		}
//This condition is used to uppercase all letters
	}
//The loop runs until Serial data is completely transmitted
	Serial.println();
//Creates a new line
	endofstring=Index;
//Stores the address of the last byte of data
	for(Index=0;Index<=endofstring;Index++)
	{
		playLetter(Input[Index]);
//Executes the playLetter function defined earlier
		delay(letterSpace);
//Waits for 3 times unit duration between letters in words
	}
	Index=0;
//Sets index back to zero before the loop restarts
