The ESP32 chip will be the heart of most of the projects we are going to build in the near future, because it offers everything we need in one low cost solution! This chip is Dual Core! It offers two 32Bit Processing Units. One is responsible for the WiFi connectivity and the other one is available for executing our code! The typical frequency of the CPU cores is 160MHz which is double than the operating frequency of the ESP8266. The chip also offers WiFi and Bluetooth connectivity, 520KBs of RAM memory, 448KBs of ROM memory, 34 GPIO pins, SPI, I2C, UART, I2S busses, up to 18 12Bit ADCs, 2 8Bit DAC, temperature sensor, touch sensor, a Hall sensor and many more things.

This book is written for readers who want to use ESP32 in depth, from basic GPIO, built-in magnetic sensor, capacitive touch switch, IoT applications, Bluetooth LE, low power sleep mode, the underlying FreeRTOS operating system, etc.

This book demonstrates how to create your own home automation devices with ESPHome on an ESP32 microcontroller board. You’ll learn how to combine all kinds of electronic components and automate complex behaviours. Your devices can work completely autonomously, and connect over Wi-Fi to your home automation gateways such as Home Assistant or MQTT broker.

This book introduces a new approach to embedded development, grounded in modern, industry-standard JavaScript. Using the same language that powers web browsers and Node.js, the Moddable SDK empowers IoT developers to apply many of the same tools and techniques used to build sophisticated websites and mobile apps.
