Visualizing Sensor Data with WebGL and WebSockets
The saying goes that a picture is worth a thousand words. By that reasoning, a web-based 3D scene complete with models, textures, lighting, and animations must be worth at least a million. It can’t be denied that data visualization can be extremely beneficial when it comes to understanding complex and frequently multi-dimensional data-sets. What better place to take advantage of these informative and rich 3D or 2D visualizations than in the field of embedded systems? It is a realm where sensors and measurements abound, and analyzing the data flow coming from them can often feel like taking a drink from a firehose. If you are still displaying your data from CSV files or boring tables, this tutorial will open your eyes to some truly amazing possibilities!

Part II: WebSockets for Real-Time Web and IoT Applications – Controlling Your NetBurner with WebSockets Interface
In this article, we will make a WebSockets dashboard application that provides real-time monitoring AND control of a NetBurner Core Module from a web browser. Previously in Part 1, we discussed the benefits of using WebSockets and demonstrated how to make a WebSockets application to remotely monitor the state of DIP switches on a NetBurner Core Module Development Kit. Next, we will build on the same example to show how we can also control the NetBurner Dev Kit’s integrated LED array in real-time from a browser using WebSockets.

Part I: WebSockets for Real-Time Web and IoT Applications
Have you ever wanted to display your real-time sensor data on a webpage that can be viewed on any device with a modern web browser? How about a web page that serves as a dashboard for controlling and monitoring your embedded device in real-time? With WebSockets, you can do exactly that! In this article, we will briefly review what a WebSocket is, how it works, its benefits, and dive into a system-monitoring, dashboard-type application tutorial.

MQTT: The Go-To Protocol for Distributed IoT and Tutorial
Imagine you have to deploy a dozen various devices throughout a factory floor. These consist of Linux PCs, low power embedded devices, a mobile phone app, simple sensors, and a remote database. Some devices are connected through Ethernet, while other more remote devices utilize a cell network to occasionally phone home. The problem you now have is, how do I get these devices communicating with each other in real time? MQTT is an ISO standard protocol used to solve this problem.
