The book "Hands-on ESP32 with Arduino IDE: Unleash the power of IoT with ESP32 and build exciting projects with this practical guide" by Asim Z. is a fantastic introduction to IOT. It covers a number of important aspects for the device side in one place. ESP32 provides a variety of device capabilities, and the Arduino IDE makes a great laboratory for learning it all with minimal friction. One of the challenges in IOT is that it requires a wide range of skills: embedded systems programming, microcontrollers and RTOS’s, electronics and device interfacing, communications technologies and protocols, backend systems for data storage and monitoring, and a variety of software. I’ve worked in IOT for almost 10 years, with WiFi, BLE, cellular, MQTT, ESP32 and the ESP-IDF, and a variety of other microcontrollers and devices connected via UART, I2C, and SPI, and this book touches on all of those. You can use it to prototype real full-featured products. It provides introductory level background on each of the topics, including cloud tools (the other end of the IOT connection). There’s a lot of background that it doesn’t have room to cover, and full productization requires additional engineering discipline, but it provides enough information to get started. That gives you a practical platform for further learning. The book relies heavily on third-party hardware modules and libraries, including open-source resources. That’s typical for the Arduino ecosystem. Most of the examples and projects in the book are small, digestible integration efforts of these, with customization for the particular application. That provides an excellent platform for learning how to apply them in full product development. The results are suitable for prototype, hobby, or one-off builds. The code for the book is included in a GitHub repository. The book includes snippets from that and briefly explains what the code is doing. #bookreview

Many thanks to Linda P. and Rohan Dobhal for sharing the book "Hands-on ESP32 with Arduino IDE" by Asim Z.! I can easily say that it is a great book for beginners and hobbyists who want to learn ESP32 development quickly. Let me start with a quick review of the chapters: Chapter 1: Introduction to the Arduino IDE with an ESP32 board. Learn how to open an Arduino sketch, build, and upload to the devkit. A must read for absolute beginners. Chapter 2: Devoted to the serial communication with other devices. Examples for I2C and SPI. Chapter 3: Discusses various display types (LCD, OLED, TFT, e-paper) with examples. Shows how to develop a camera application with a ESP32-CAM devkit Chapter 4: Explores networking protocols (native on ESP32 - Wifi & BLE, and with extension boards, such as cellular communication and LoRaWAN) Chapter 5: IoT protocols to exchange data with 3rd parties Chapter 6: The first full-fledged project of the book - plant monitoring system that integrates with the 3rd-party service providers for delivering events over different messaging platforms. Chapter 7: Parking space project with PayPal integration Chapter 8: Smart home project that employs InfluxDB, Grafana, and HiveMQ as the MQTT broker. Chapter 9: Next steps for IoT development with ESP32 What I liked most about this book is that it showcases numerous examples of integrations with third-party services. Sending emails over Gmail, connecting to the weather service, and MQTT communication over HiveMQ are just a few of them. The book also employs a wide range of sensors throughout. The comparison tables provided in the chapters are quite useful for understanding the topics and help readers to decide among the alternatives when necessary. The example applications are relevant and clear, but I'm especially impressed by the projects in Chapters 6, 7, and 8, as they demonstrate the true power of IoT in meaningful use cases. On a slightly more critical note, it could be worthwhile to discuss other series in the ESP32-family of SoCs, such as the ESP32-S and ESP32-C, in the last chapter. I believe this could shed light on ways to further improve and expand on this journey. You can find the book here: https://lnkd.in/efjhHcid #internetofthings #esp32 #arduino #bookreview Packt
