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.

Controlling an OLED screen

To make your ESP8266 projects more interactive, you have to use more comprehensive ways of displaying data and information. This can be achieved with an OLED screen. Using it, you will be able to display writing and images, enabling one to know the current state of the project and to monitor its operations. In this recipe, you will learn how to control an OLED screen to display information on an ESP8266 project.

Getting ready

You will need an ESP8266 board, a USB cable, and a few other components, which include:

The monochrome 1.3" 128x64 OLED graphics display pin configuration is shown in the following diagram:

The display has two interfaces that you can use to communicate with the ESP8266 board. They are i2C and SPI interface. When using the i2C interface, the pin connections should be as follows:

  • GND of the display goes to GND of the ESP8266 board

  • Vin of the display...
