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
· Build practical electronics projects with an ESP8266 or ESP32 microcontroller with Wi-Fi communication· 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
· Apply your computer programming skills in C++, JavaScript, AJAX and JSON· Use WebSocket, MQTT brokers and IFTTT for fast two-way communication with webpages
Who This Book Is ForThe target audience is for Makers and Tinkerers who want to build internet/intranet based applications with more powerful microcontrollers, such as the ESP8266 or ESP32. A level of C++ programming expertise with the Arduino IDE is assumed, although all sketches are fully described and comprehensively commented.896 kr

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.
Just as there are different communication protocols, there are different ESP32 microcontroller formats. You’ll examine the features of several ESP32 microcontroller formats, which enable the optimal combination of communication protocol and ESP32 format to achieve the requirements of a project. Several of the communication protocols and ESP32 formats have only been available in the last few months or years, making the book very relevant.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.
What You''ll Learn
Study the MESH communication protocol and the ESP-NOW protocol with communication between ESP32 microcontrollers without a Wi-Fi connectionReview email communication projects with an ESP32 and generation of quick response codes to instruct an ESP32 to control a connected device.Look at the ESP32-CAM module built around a 2M-pixel camera for streaming images with the WebSocket protocol to a remote ESP32Control an ESP32-CAM robot car through remote communication over the internet with image streaming to an Android tablet or mobile phone.Who This Book Is For667 kr
