More and more common objects and devices around us are being connected to the Internet. From lights, heaters, and sensors in and around the home to cars, traffic lights, shipping containers and much more, together they all communicate and form the Internet of Things (IoT). To connect a device to the IoT it needs networking capabilities so it can exchange information with servers, clouds, clients, users and other devices. In this Elektor webinar about ESP32 and the IoT, which is hosted by Jens Nickel and Mathias Claussen, you will learn how to do that.

Webinar: ESP32 and the IoT

The webinar “ESP32 and the IoT” explains how the popular ESP32 can be connected to the cloud to allow it to be controlled remotely from anywhere on the world. The following topics are being discussed:
 
  • What is the Internet of Things (IoT)?
  • What is the ESP32 and ESP32-C3?
  • What is MQTT? This acronym that doesn’t really stand for anything pops up as soon as you try to connect something to the cloud or a home automation network. What does it mean and why should you know about it?
  • What is JSON? JavaScript Object Notation better known as JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays. It is widely used in IoT applications.
  • Required Arduino framework and libraries to write programs for the ESP32. What do you need and how to set it up?
  • A practical example! A good way to get started in IoT is with a simple practical example, for instance connecting a Wi-Fi-enabled push button to a Wi-Fi-enabled relay; the relay can be activated remotely by the button and reports its status back to the push button.
