Overview of this book

The ESP8266 Wi-Fi module is a self-contained SOC with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It has a powerful processing and storage capability and also supports application hosting and Wi-Fi networking. This book is all about robotics projects based on the original ESP8266 microcontroller board and some variants of ESP8266 boards. It starts by showing all the necessary things that you need to build your development environment with basic hardware and software components. The book uses the original ESP8266 board and some variants such as the Adafruit HUZZAH ESP8266 and the Adafruit Feather HUZZAH ESP8266 . You will learn how to use different type of chassis kits, motors, motor drivers, power supplies, distribution boards, sensors, and actuators to build robotics projects that can be controlled via Wi-Fi. In addition, you will learn how to use line sensors, the ArduiCam, Wii Remote, wheel encoders, and the Gripper kit to build more specialized robots. By the end of this book, you will have built a Wi-Fi control robot using ESP8266.

Preface

Writing the Arduino UNO sketch


First, generate the Arduino UNO sketch that shows how to read values from virtual pins with the Adafruit HUZZAH and ESP8266 Wi-Fi by using the Blynk Sketch Builder (https://examples.blynk.cc). The following instructions will show you how to generate the example sketch with the Blynk Sketch Builder (Figure 4.9):

  1. Select Adafruit Huzzah from the Board drop down list.
  2. Select ESP8266 WiFi from the Connection drop down list.
  3. Type the Auth Token associated with your Blynk app in the Auth Token(optional) text box.
  1. Select Virtual Pin Read from the Example drop down list:

  1. Click the Copy example button in the Blynk Sketch Builder to copy the code onto the clipboard.
  2. Then, start the Arduino UNO IDE, create a new file, delete the default sketch, and paste the example code.

The example code generated with the Blynk Sketch Builder can be modified to control the two motors with the Joystick widget through...
