This book takes you on an interesting journey through wearable technology, starting from electronic circuits, materials, and e-textile toolkits to using Arduino, which includes a variety of sensors, outputs, actuators, and microcontrollers such as Gemma M0 and ESP32. As you progress, you'll be carefully guided through creating an advanced IoT project. You'll learn by doing and create wearables with the help of practical examples and exercises. Later chapters will show you how to develop a hyper-body wearable and solder and sew circuits. Finally, you'll discover how to build a culture-driven wearable to track data and provide feedback using a Design Innovation approach.

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.
