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.

EXPANDED TECHNICAL DETAILS

Cross-Platform Signal Monitoring

This project enables professional-grade data visualization by bridging the Arduino's local sensing with the graphical power of the Processing IDE.

  • High-Speed Serial Telemetry: The Arduino captures I/O states and PWM values (0-255) and streams them as formatted CSV packets over a Serial link (USB).
  • Dynamic Waveform GUI: The Processing script parses the stream and renders a live, multi-channel chart. It visualizes the discrete digital "Stepping" of a PWM signal or the fluctuating analog values of a sensor, acting as a "Software Oscilloscope."

Debugging Power

  • Live Calibration: Users can see the exact effect of their code changes in real-time on a large monitor, making it much easier to fine-tune sensitivity thresholds for robotics or industrial projects.
