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 a servo motor

In this section, we are going to look at how to use the functionalities of the ESP8266 to control a servo motor. We will be rotating the servo motor to a specific position in either direction at a set speed. This will demonstrate the different servo motor parameters we can control using an ESP8266 board.

Getting ready

Make sure you have all the components before proceeding. They include:

Start by mounting the ESP8266 board onto the breadboard. Use jumper cables to connect the power wires of the servo to the ESP8266 power pins. The power wires of the servo are coloured red for the positive terminal and black/brown for the negative terminal.

Connect the positive terminal to the USB pin of the ESP8266 board and the negative terminal to the GND pin of the ESP8266 board. We connect the positive terminal to the USB pin because it provides 5V, which is within the recommended...
