Introduction

This beginner blueprint introduces the Serial terminal over USB. You'll learn how to open a serial monitor and use a Particle Cloud function to print messages for quick debugging.

Supported devices

Any Wi-Fi or Cellular Device

Hardware and supplies

  • Supported Particle device
  • USB cable

Project description:

The firmware initializes USB Serial at 9600 baud and registers a cloud function called printMsg. When invoked from the Particle Console (optionally with an argument), the device prints a timestamped message to the terminal. This provides a simple, reliable pattern for interactive debugging.
