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.

A basic DC motor prototype

In this section, we will build a prototype where a DC motor will spin for a second every time a push button is pressed.

For building the distance measurement device, the following parts will be required:

  • Arduino Uno R3
  • USB connector
  • Four pieces 1.5V batteries
  • One battery holder (for 4 batteries)
  • One full sized breadboard
  • One push button
  • One piece 10K Ohms resistor
  • One small DC motor
  • One N2222 transistor
  • One IN4001/IN4007 diode
  • Two pieces 150 Ohms resistors
  • Some Jumper wires

Follow the schematic diagram shown below to build the DC motor circuit. In the following breadboard diagram, notice that an external battery-based power source has been used for powering the DC motor; whereas the Arduino board has been powered via the computer USB.

Using a separate power source for the DC motor is important, because the 5V pin of the Arduino board is not designed...
