Advanced projects with Arduino and ESP32 (Paperback)

From turning on an LED diode to controlling a robot. From measuring distances to predicting earthquakes. With Arduino and ESP32, you can automate and control practically anything that works with electricity.
Focused on the new R4 WiFi version of Arduino and the ESP32, “Advanced Projects with Arduino and ESP32” will show you a wide variety of projects to provide you with the vision and tools you need to develop your own ideas using these two families of microcontrollers.

Whether you have just started in the world of microcontrollers or have already completed several projects, this book aims to take things one small step further, demonstrating that a microcontroller is not an isolated device, but rather one designed to work with many other elements. In addition, with the advent of cloud programming and voice assistant systems, the range of possibilities becomes much broader.

What do you need to know to read this book properly?

This is not a book for learning how to program, so you need to have some level, however basic, of programming knowledge; that is, you should know what variables, loops (for), and conditionals (if) are and how to use them. That is enough to make the most of all the content.

And what will you learn by reading it?

With this book, among other things, you will learn the following:

• Learn about the different families of Arduino and ESP32 microcontrollers and the practical use of each one.

• Take advantage of the new capabilities of the Arduino R4 WiFi version.

• Connect different elements to the microcontrollers and interact with them.

• Communicate between Arduino and ESP32 boards and with external devices.

• Take advantage of WiFi and Bluetooth communication capabilities.

• Turn the microcontroller into an automated keyboard and mouse.

• Access the microcontroller from anywhere in the world by turning it into a WEB server.

• Program in the cloud, interacting with your microcontroller from a PC or mobile device.

• Integrate your circuits with Alexa and send them commands through voice.

Explained in a didactic and completely practical way, with step-by-step projects full of images, diagrams, and complete source code so that you do not get stuck at any point, you will not only
learn about new applications of microcontrollers, but will also dive headfirst into the world of the Internet of Things.

We are in the era of IoT. It is time to move forward.
