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.

Things to remember

Remember the following important points about what we learnt in this chapter:

  • A relay is used to interface the Arduino board (or other micro-controller devices running on DC power) with AC powered equipment
  • The positive end of the AC electric supply is connected to the COM port of a relay
  • The positive end of the AC powered equipment is connected to the NO port of a relay
  • The IN/IN1 port of a relay is used to accept a signal from Arduino, based on the signal the relay either switches ON (closed state) or OFF (open state)
  • The digitalRead function is used to read input signals via Arduino's digital pins
  • The digitalWrite function is used to send output signals via Arduino's digital pins.
