Getting Started With the Internet of Things (IoT)

Course Overview:

Internet of Things (IoT) is a broad term that describes things (devices) that are connected in some way, usually via the Internet. For example location sensors on sheep that connect to the mobile network so that the farmer can log on to a web page and see the location of each animal.

But it can also be a local network of connected things. If for example the sheep sensors were connected to a local wireless network without any internet access, it would still be considered an IoT system.

In this course, you will learn the basics of IoT, such as the communication protocol used, and the different components you need to have in place to build an IoT system.

Then you'll build your own IoT project (using ESP32, MQTT, and a mobile application) where you'll control an LED over the Internet. This is a great beginner's project that you can customize and expand on after completing this course.

You are going to use the ESP32, which is one of the most popular chips used for DIY IoT projects today. It's the successor to the ESP8266 chip which was one of the most used WiFi chips ever.

Components Needed:

  • ESP32 development board (with USB cable)
  • Breadboard
  • LED
  • 330 ohm resistor
  • A computer with Arduino IDE
  • A WiFi network to connect to

Here are few options on where to by an ESP32 board:
