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.

Local storage with SD card modules

SD card storage is a relatively wide subject. Therefore, we will focus on the basics of interfacing, reading, and writing data to and from a micro SD card with the Arduino Uno platform. At the end of this topic, you will clearly understand how SD cards can be used in any electronic device for local storage capabilities.

In the example that we will build, our focus will be to understand the following basic activities:

  • Reading pre-configured data from an SD card and then using it in the C sketch
  • Writing new data to local files that can be ported or transferred to other mediums as required

Reading pre-configured data from an SD card is a common technique to have an external place to store the values of variables that are used in the C sketch. This is a normal practice to read system configurations from a local storage device. The variables in...
