Neil Cameron – författare

Discover the powerful ESP8266 and ESP32 microcontrollers and their Wi-Fi communication. The ESP32 microcontroller features Bluetooth and BLE communication in addition to Wi-Fi. The book emphasizes practical projects and readers are guided through Wi-Fi and Bluetooth communication, mobile app design and build, ESP-NOW and LoRa communication, and signal generation.

Projects throughout the book utilize the Wi-Fi functionality and processing power of the ESP microcontrollers. Projects are built in the Arduino IDE, so you don''t need to download other programming software. Mobile apps are now ubiquitous, making the app build projects of the book very relevant, as are the web page design projects.

In Electronics Projects with the ESP8266 and ESP32, you''ll see how easy and practical it is to access information over the internet, develop web pages, build mobile apps to remotely control devices with speech recognition or incorporate Google Maps in a GPS route tracking app.

You will

·       Use the Wi-Fi function of the ESP8266 and ESP32 to update web pages

·       Communicate with your mobile phone or smart watch by Bluetooth Low Energy

·       Transmit and receive information to control remote devices over the internet

·       Understand the design and build of mobile apps for internet based applications

·       Use WebSocket, MQTT brokers and IFTTT for fast two-way communication with webpages

Although Wi-Fi communication is incorporated in many internet-based applications, knowledge of alternative communication protocols is vital for optimal project development with a microcontroller, such as the ESP32. This book focuses on communication protocols for the ESP32 microcontroller with illustrative projects ranging from a Bluetooth Low Energy beacon communicating with your smart wristwatch to Long Range (LoRa) communication between microsatellites circling 550km above the Earth and an ESP32 microcontroller in your home.

Eachchapter focuses on a communication protocol and is stand-alone, so they can be read without having to start from the beginning of the book. The chapters are loosely grouped into short- and long-range communication, image management for transmission to a webpage or a remote LCD screen, and the required apps and IoT techniques for remote control of an ESP32-CAM robot vehicle. The advantages of each communication protocol correspond to different project types.
