Azzimutt:
Thanks for the information, do you know any tutorial like this but for sending multiple data? I was looking for it but i didn't find anything.
I had hoped that would be obvious from the receiving code.
For example you can send <num1, num2> with
Serial.print('<');
Serial.print(num1);
Serial.print(',');
Serial.print(num2);
Serial.print('>');
