This project is the natural completion of Remotino, and serves to visualize on PC the PWM and I / O values present in Arduino Nano, on the PC video using Processing.
I created a virtual console on a PC, connected to the Arduino Nano USB serial port. Whenever a procedure changes the value of the PWM for the engines, or the status of an output, Nano transmits new values with a simple ASCII code to the PC, which decodes it and displays it.

Questo progetto è il completamento naturale di Remotino, e serve a visualizzare su PC I valori di PWM e I/O presenti in Arduino Nano, sul video del PC usando Processing.
Ho creato una console virtuale su PC, connessa con la seriale USB di Arduino Nano. Ogni volta che una procedura cambia valore del PWM per I motori, o lo stato di un Output, Nano trasmette I nuovi valori con una semplce codifica ascii al pc, che lo decodifica e lo visualizza.
/** Example of selecting a particular Serial Port
* pautax: ripete la porta seriale selezionata sull'area nera
* gauge 3 scan continuo
* from the list of all possibilities returned
* in Serial.list().
*
* Uses showInputDialog box kindly suggested to
* me by GoToLoop. Thank you, GoToLoop!
