/* ------------------------------------------------
* SERIAL COM - HANDELING MULTIPLE BYTES inside ARDUINO - 01_simple version
* by beltran berrocal
*
* this prog establishes a connection with the pc and waits for it to send him
* a long string of characters like "hello Arduino!". 
* Then Arduino informs the pc that it heard the whole sentence
*
* this is the first step for establishing sentence long conversations between arduino and the pc.
* serialRead() reads one byte at a time from the serial buffer.
* so in order to print out the whole sentence at once 
* (it is actually still printing one byte at a time but the pc will receive it
* not interupted by newLines or other printString inside you loop)
* You must loop untill there are bytes in the serial buffer and 
* and print right away that byte you just read.
* after that the loop can continue it's tasks.
