Wireless Communications with Arduino and the ESP32

UPDATED in 2023 for Arduino IDE 2.0 and the Arduino Nano 33 IoT.

In this, the seventh book in the Arduino Short Reads Series, we take an in-depth look at wireless communications with Arduino. This is an especially important area as communications with smart devices being a key aspect of the Internet of Things. We will take you from first principles of radio communications and look at Bluetooth, Wi-Fi, and the Internet. Furthermore, we augment your native Arduino knowledge by introducing you to the extremely capable and Arduino IDE compatible ESP32 microcontroller. A further chapter has been added to this edition to cover the new range of Arduino Nano boards and we see how Wi-Fi and Bluetooth connectivity work on the Arduino Nano 33 IoT.

There are now 10 experiments to help reinforce your new knowledge. Learn how to use Smartphone sensors to control the LEDs, build a web server on the ESP32 and access data from the Internet to enhance your projects.

There are over 680 pages of material in the overall series of books and 76 experiment! The series really is a comprehensive and definitive guide to the Arduino ecosystem, foundation electronics and coding.

Other books in the series cover the following subjects:
Book 1 – First Steps with Arduino
Book 2 – Working with Displays
Book 3 – Controlling Motors
Book 4 – Range Finding, Object Detection and Object Avoidance
Book 5 – Building a Simple Rover
Book 6 – Arduino Special Functions
