Preface to Make: Sensors: A Hands-On Primer for Monitoring the Real World with Arduino and Raspberry Pi PDF
Welcome to Make: Sensors. Soon you’ll be making gadgets that can sense it all—from dangerous gases to acceleration. In this book, you’ll use sensors to measure the physical world, represent the result as a numeric value, and take some action based on that value.
For example, a sensor could measure heat, pressure, light, or acceleration and report a value such as 22 C, 1015 millibars, light is detected, or 2.3 g acceleration (in the case of light, notice that we represented it as a Boolean or yes/no value rather than a numeric quantity; you’ll see examples of this later). A microcontroller board is the brain of the robot, system, or gadget you’re building.
You’ll write your own software to run on the microcontroller. In this book, you’ll work with two very popular boards: Arduino and Raspberry Pi. Either of these makes it easy to write software code to work with electronics.
It’s About Your Ideas If your interest in electronics started with a desire to quickly learn some basics and then design your own robots, gadgets, or projects, you’re in the right place. This book will show you how to go from idea to reality quickly. Theory, skills, and basics are useful—as long as they serve your creativity.
Feel free to experiment with your ideas, and have the courage to publish your results on the Web. Each chapter presents a mini project to show how you can combine different technologies. For example, you’ll build a wooden box that you open with a fingerprint and a color-changing chameleon dome. These are fun projects, but also good starting points for things you invent later yourself. The skills you learn with Arduino are easily applicable to real-life projects.
