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.

Building a smoke detector

The smoke detector device prototype will be built using a MQ2 series gas detector module and a Piezo Buzzer. The MQ2 series sensor is a general-purpose gas sensor: it can be used for sensing different types of gases (including LPG); today, we will use this sensor for detecting smoke.

As we have seen in the earlier chapters, a Piezo Buzzer is a small acoustic device that is capable of emitting sounds at various frequencies. In this example, we will write the corresponding Arduino sketch for detecting smoke and then buzzing the Piezo Buzzer five times at one second intervals. After completing Chapter 11, Day 9 - Long Range Wireless Communications which deals with GSM communications, you may use the GSM module with this chapter to send an SMS or dial a number automatically as soon as smoke gets detected. Wouldn't that be awesome!?
