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.

External power supply options

The Arduino Uno board has three different options for receiving power:

  • USB B port
  • DC IN power socket
  • VIN pin

Providing power via the USB B port in a standalone manner can be achieved via USB power hubs. These USB power hubs are also sometimes called USB power banks. The USB B port can receive 5 volts of power.

The DC IN power socket can receive power supply from external batteries as well as AC to DC wall adapters. The DC IN socket can receive 7-12 volts of power supply.

The VIN pin provides yet another option for receiving power from external power supplies. In this case, mostly, external batteries are used. Similarly, the VIN pin can also receive 7-12 volts of power.

As a caution, avoid an input voltage on the 5V pin, as the input voltage to the 5V pin will bypass the on-board voltage regulator and enter the main board circuit directly. This will...
