Welcome to the Hello World Blueprint App for Particle devices! This project serves as a starting point for new users to get acquainted with Particle's IoT platform. It demonstrates a simple yet powerful "Hello, World!" program that connects your Particle device to the cloud, sending real-time messages visible on the Particle dashboard.
Use this blueprint to begin your IoT journey! Simply follow the instructions to set up, flash, and monitor your device as it comes alive with your first cloud-connected message.
For this project, you’ll only need a Particle device. Any Particle MCU Development Board is supported, so pick one and get started.
-
Set up your Particle Device
Visit setup.particle.io to configure your device and connect it to your Particle account. This ensures your device is ready to flash the Hello World firmware. -
Flash the Firmware
Using the Particle Developer Tools, open this project in Visual Studio Code or another editor with Particle support. Then, either use the Cloud Flash command in Visual Studio Code or run the following command in the Particle CLI:
particle flash <device_name> hello-world
Once flashed, your device will automatically start sending the "Hello, World!" message to the Particle dashboard. You can view it in real time by visiting your Particle Console.
- Monitor the Device
Open a serial monitor to observe the device's output. In Visual Studio Code, access the Particle: Serial Monitor command in the command palette, or use:
particle serial monitor –follow
Your device is now running the Hello World app!
