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

Testing the robot


This test allows you to fine-tune and correct the rotating directions of the motors:

  1. Slide the power switch of the 4 x AA battery case to supply the power to the motors through the motor driver.
  2. Open your Blynk app and allow it to connect with the robot.
  3. Initially, the joystick handle will be at the center position. Move the handle forward and hold to drive the robot forward. Sometimes, the motors may not rotate in the forward direction and result in an erratic behavior. You can change the direction by simply swapping the two wires from the motor to the motor shield. Once you fix the forward direction of the motors, the other directions will also be fixed.
  4. Move the handle to the left. The robot will make a point turn to the left continuously until you release or move the handle to a different position.
  5. Release the handle to automatically return it to the center position. The robot will stop immediately.
  6. Move the joystick handle backward and hold to drive the robot backward. Then...
