Overview of this book

Develop the skills essential for building Internet of Things solutions with this indispensable guide. In an era where industries heavily rely on IoT, this book will quickly familiarize you with its foundations, widespread use, implementation guided by best practices, and the crucial technologies that allow it to work effectively. Starting with the use of IoT in real-life scenarios, this book offers comprehensive insights into basic IoT hardware, protocols, and technologies. You’ll then learn about architecting and implementing solutions such as wireless sensor networks, cloud computing with AWS, and crucial security considerations. You’ll understand how these systems are operated and monitored over time and work with simple to complex, industry-grade systems, adhering to best practices. In later chapters, you’ll be apprised of future IoT trends and strategies to manage the risks and opportunities that come with them. You’ll also get to grips with a diverse set of tools, including hardware such as ESP32 and Raspberry Pi, and software such as Mosquitto and ChatGPT for generative AI capabilities. By the end of this IoT book, you’ll be able to independently build and design complex, industry-standard solutions fully aligned with best practices.

Technical requirements

This chapter will require you to have the following hardware installed:

  • ESP32-CAM
  • Single channel relay
  • 1 1k ohm resistor
  • Push button switch
  • Jumper cables
  • Breadboard

Here’s the list of software you’ll need for this chapter:

  • Blynk app
  • Arduino IDE

The Blynk app

Blynk is a platform that allows users to build graphical user interfaces (GUIs) with ease, which allows them to monitor and control IoT devices. It provides a wide number of widgets, such as buttons, sliders, or gauges, that can be added to the GUI and have specific actions linked to them or data points on the device. It can be downloaded as an app on iOS or Android and can serve as a bridge between the GUI and the device, allowing users to remotely control and monitor the device from the convenience of their smartphone or tablet.
