A Simple Example (Arduino, MQTT, m2m.io)

This project is a simple example of using MQTT and the m2m.io platform, but it is a good illustration of how we retrieve sensor values from a cloud-hosted API with Arduino Ethernet Shield.

This project is a simple example of using MQTT and the m2m.io platform, but it is a good illustration of how we retrieve sensor values from a cloud-hosted API with Arduino Ethernet Shield.

There are four main tasks the Arduino software needs to take care of for this example:

  • Gather light sensor readings periodically
  • Publish sensor readings via MQTT
  • Listen for commands via MQTT
  • Control the LED based on a setpoint

This source code requires both the Ethernet library and MQTT Client Library to be installed in your Arduino library folder. See an example here on how to install Arduino libraries – It’s easy!

This project uses ThingFabric platform. In detail, please refer  Connecting to ThingFabric with an Arduino.

You can get all source code and all detail about the project from below link.
