Make:

Action

Movement, Light, and Sound with

Arduino and Raspberry Pi

Simon Monk

Technology & Engineering / Robotics

Make:

Action

Beginning with the basics and moving gradually to greater challenges, this

book takes you step-by-step through experiments and projects that show

you how to make your Arduino or Raspberry Pi create and control movement,

light, and sound. In other words: action!

The Arduino is a simple microcontroller with an easy-to-learn programming

environment, while the Raspberry Pi is a tiny Linux-based computer. This

book clearly explains the differences between the Arduino and Raspberry Pi,

when to use them, and to which purposes each are best suited.

Using these widely available and inexpensive platforms, you'll learn to control

LEDs, motors of various types, solenoids, AC (alternating current) devices,

heaters, coolers, displays, and sound. You’ll even discover how to monitor

and control these devices over the Internet. Working with solderless

breadboards, you’ll get up and running quickly, learning how to make projects

that are as fun as they are informative.

Make: Action,

you'll learn to:

Build a can crusher using a linear actuator with your Arduino

Have an Arduino water your plants

Build a personal traffic signal using LEDs

Make a random balloon popper with Arduino

Cool down your beverages with a thermostatic drink cooler you build yourself

Understand and use the PID control algorithm

Use Raspberry Pi to create a puppet dance party that moves to your tweets!

Learn how to control mechanisms and systems, and then jump into the

Internet of Things (IoT) to connect with today's newest technology.

Hello, World? Hello,

Universe!
