B-1 Start IoT Device

Let's start your Photon to verify it connects to Wi-Fi and Particle Cloud.

Power On Photon

Start your Photon by powering on the circuit board:

  • Connect a power cable into the barrel jack or Micro-USB port on the circuit board, and connect the other end of the cable to a power source (such as: battery, computer USB port, etc.).

CHOOSE ONE: Only one power source (barrel jack or Micro-USB) needs to be connected.

Once the circuit board has power, you should see its red Power LED light turn on.

You should also see the RGB LED light turn on – it will blink green while the Photon automatically tries to connect to Wi-Fi.

Once the Photon has successfully connected to Wi-Fi and Particle Cloud, the RGB LED will be cyan (light blue) and "breathing" (slowly blinking).

CONNECTION ISSUES: If your Photon is having issues (can't connect to Wi-Fi, etc.), you'll see a different RGB pattern (such as: breathing green, breathing pink, etc.). You may have to consult with your teacher to troubleshoot your device.

How does Photon connect to Wi-Fi?

When your Photon is powered on (or restarted), it will automatically try to connect to a Wi-Fi network. It does this by using its saved list of Wi-Fi logins (network names and passwords). Every Photon can be programmed to store login information for up to 5 different Wi-Fi networks.

A brand new Photon will not have any Wi-Fi logins saved yet. However, the Photon provided to you by your teacher will most likely already have a Wi-Fi login programmed into it.

What is Particle Cloud?

Once your Photon is connected to Wi-Fi, the Photon will automatically try to connect to Particle Cloud, which is a cloud service that Particle provides for all of its microcontroller devices. All of your Photon's internet communications are routed through Particle Cloud.

Particle Cloud can be used to:

  • Code and store all your different Photon device apps (using Particle Build code editor)

  • Update the app stored on your Photon device

  • Update the firmware on your Photon device

  • Send and receive data between your Photon device app and your web app

  • Manage your Photon device remotely
