Electronics Projects with the ESP8266 and ESP32: Building Web Pages, Applications, and WiFi Enabled Devices

Build more than a blinking LED: Neil Cameron’s practical electronics projects show how ESP8266 and ESP32 microcontrollers can connect devices, web pages, mobile apps, and sensors. The projects move from familiar applications such as internet radio and weather stations to web communication, GPS tracking, wireless control, and electrical measurement.

Connected projects, from web pages to GPS

The book explores the boards’ Wi-Fi capabilities and, with the ESP32, Bluetooth and BLE. Projects include an intranet camera, an internet clock, a Bluetooth speaker, app-controlled devices, GPS tracking with Google Maps, and communication using ESP-NOW, LoRa, and radio frequency. The variety makes it possible to see how microcontrollers can serve different roles in connected electronics—not just one kind of build.

Bring hardware and software together

Alongside the circuits and devices, Cameron covers web-page updates, WebSockets, mobile-app design, and ways to transmit information for remote control. Programming topics include C++, JavaScript, AJAX, and JSON. The projects use the Arduino IDE, and the publisher notes that the sketches are described and commented.

Explore signals, sensors, and measurement

Later projects turn to signal generation, 555 timer circuits, rotary encoder control, and measuring voltage, resistance, and current. There is also material on saving data to EEPROM and SPIFFS, over-the-air updates, and exporting data to Excel.

Who will find it useful?

This is aimed at makers and tinkerers interested in internet- or intranet-connected projects with ESP8266 and ESP32 boards. The publisher assumes some C++ experience with the Arduino IDE, making the book a better fit for readers ready to build and adapt projects than for someone seeking a first introduction to programming.

For electronics enthusiasts who want their microcontroller projects to communicate—with a browser, an app, a sensor, or another device—this collection offers a broad set of practical directions to explore.
