The Internet of Things (IoT) involves rapidly creating connected devices, applications, and services, with software and hardware engineers playing integral roles in developing prototypes. Using tools like the Arduino Uno and the Johnny-Five robotics framework, which allows hardware programming in JavaScript, developers can quickly build IoT prototypes. This tutorial demonstrates streaming sensor values from an Arduino microcontroller to a live dashboard, enabling real-time device monitoring and control via PubNub's APIs. These APIs facilitate real-time global streaming of sensor data, while Project EON, an open-source JavaScript framework by PubNub, allows real-time charting and mapping of this data. The convergence of JavaScript with hardware simplifies the exploration of IoT for software developers, encouraging them to venture into this interconnected technology landscape.
