Smart Home Prototyping: Arduino MQTT Bridge

Introduction

This advanced prototyping tutorial explores how we can bring ProtoPie prototypes to life with real data coming from platforms that run on MQTT by using an Arduino as an intermediary bridge. This solution enables, although in a more cumbersome way, non-enterprise teams to achieve MQTT communication without the need for Socket.io, until they are ready to scale up to an enterprise plan.
