Learn Arduino Prototyping in 10 days

By: Kallol Bosu Roy Choudhuri

Overview of this book

This book is a quick, 10-day crash course that will help you become well acquainted with the Arduino platform. The primary focus is to empower you to use the Arduino platform by applying basic fundamental principles. You will be able to apply these principles to build almost any type of physical device. The projects you will work through in this book are self-contained micro-controller projects, interfacing with single peripheral devices (such as sensors), building compound devices (multiple devices in a single setup), prototyping standalone devices (powered from independent power sources), working with actuators (such as DC motors), interfacing with an AC-powered device, wireless devices (with Infrared, Radio Frequency and GSM techniques), and finally implementing the Internet of Things (using the ESP8266 series Wi-Fi chip with an IoT cloud platform). The first half of the book focuses on fundamental techniques and building basic types of device, and the final few chapters will show you how to prototype wireless devices. By the end of this book, you will have become acquainted with the fundamental principles in a pragmatic and scientific manner. You will also be confident enough to take up new device prototyping challenges.

Interfacing with a servo motor

Let us take a look at yet another very useful example of an actuator: the servo motor. A servo motor is a special type of motor that is capable of rotating its shaft at specified angles between 0 to 180 degrees.

A DC powered servo motor has numerous applications in electronic gadgets such as surveillance cameras, DVD players, and basically any application where things need to be moved at particular angles. AC powered servo motors are usually applied in the manufacturing industry to move machinery parts at specified angles - a common example would be a bottling plant:

Internally, a servo motor has a regular DC motor that is integrated with an in-built motor driver circuit. The in-built driver circuit takes care of moving the motor at specified angles. Signals are sent from the Arduino to the servo motor, via an Arduino...
