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.

Smoke detector - Digital I/O method

Overall, the general steps to interface the Arduino with a sensor device, as outlined in Chapter 4, Day 2 - Interfacing with Sensors, will be followed once again in this chapter. However, you will notice that for the smoke detector, we do not require an Arduino library. The reason is because the smoke detector's output can be directly read via an analog pin or via a digital pin.

For building the smoke detector project the following parts will be required:

  • Arduino Uno R3
  • USB connector
  • 1 bread board
  • 1 MQ2 gas sensor
  • 1 Piezo Buzzer
  • 1 pc. 100 ohms resistor
  • Some male-to-male jumper wires
  • Some female-to-male jumper wires

First, let us inspect the method of using the digital pin; after that we will see the method of using the analog pin. Just so you know, it may be a little difficult to trigger smoke detection using the digital pin method, compared...
