What is IoT?

Internet of Things (IoT) is an emerging field that focusses on connecting everyday objects to the Internet. What does it mean to connect everyday objects to the Internet? It means to implement clients and servers on low-power, low-cost, small computers (known as microcontrollers) to control everyday objects. This section will teach you the basics of programming clients/servers on ESP32, a production ready IoT platform.

Why IoT?
