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 distance measurement device

Let's build an exciting project by combining an Ultrasonic Sensor with a 16x2 LCD character display to build an electronic distance measurement device. We will use one of the most easily available 9-volt batteries for powering this standalone device prototype.

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

  • Arduino Uno R3
  • USB connector
  • 1 pc. 9 volt battery
  • 1 full sized bread board
  • 1 HC-SR04 ultrasonic sensor
  • 1 pc. 16x2 LCD character display
  • 1 pc. 10K potentiometer
  • 2 pcs. 220 ohms resistor
  • 1 pc. 150 ohms resistor
  • Some jumper wires

Before we start building the device, let's understand what the device will do and the various parts involved in the device. The purpose of the device will be to be able to measure the distance of an object from the device. The following diagram depicts the overview...
