This repo contains the source code to help you get familiar with Azure IoT using the Azure IoT Adafruit Feather M0 WiFi Starter Kit. You will find the lesson-based tutorials on Azure.com.
This repo contains an arduino application that runs on board Feather M0 WiFi with a BME280 temperature&humidity sensor, and then sends these data to your IoT hub. At the same time, this application receives Cloud-to-Device message from your IoT hub, and takes actions according to the C2D command.
Install board with your Arduino IDE
Follow this page to install the board managers for your M0 WiFi.
Install the following libraries from
Sketch -> Include library -> Manage libraries
- Adafruit BME280 Library
- Adafruit Unified Sensor
Connect your sensor with your board
Connect with a physical BME280 sensor
You can follow the image to connect your BME280 with your Feather M0 WiFi.
DON'T HAVE A PHYSICAL BME280?
You can use the application to simulate temperature&humidity data and send to your IoT hub.
1. Open the
2. Change the
SIMULATED_DATA value from
Configure and run sample application
app.ino to your board.
Input your credential information
After you successfully upload the code to your board. You will see some prompt, input your credential information according to the prompts.
Send Cloud-to-Device command
You can send a C2D message to your device. You can see the device prints out the message and blinks once receiving the message.
