Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Discovering the MicroPython language

In this recipe, we will look at some of the basics of MicroPython. This will give you a clear understanding of the structure and different features of the MicroPython programming environment.

Discovering MicroPython

MicroPython is basically Python with some additional libraries to control boards. It comes with an interactive prompt known as the MicroPython Interactive Interpreter mode or Read-Eval-Print-Loop (REPL). REPL runs and imports scripts from the built-in filesystem. It also comes with several features that enhance your coding experience. These features include:

  • Auto-indent

  • Auto-completion

  • Interrupting a running program

  • Paste mode

  • Soft reset

  • Special variable

  • Raw mode


The auto-indent feature keeps your programs neat. When you type a statement that ends with a colon (:), such as for or while loops or if statements, the prompt changes to three dots () and the cursor gets indented by four spaces. The next lines after that continue on the same level...
