Arduino For Dummies 3rd Edition – John Nussey

Make your basic prototypes into something more solid by learning about soldering. Use code to improve the reliability of your project. Learn how to choose the right sensors for your projects. Discover new possibilities by using shields and libraries. CHAPTER 8 Learning by Example 151 Chapter 8 Learning by Example ne of the best ways to learn about Arduino is by seeing what others have done with it.

Since its release, Arduino has powered an enormous variety of projects — from interactive artworks and scientific tools to connected consumer products. Some of these projects have gone on to shape how designers and engineers think about hardware prototyping. In this chapter, you look at a handful of influential projects that show what’s pos- sible with simple boards and creative thinking. Each one demonstrates a different aspect of Arduino — sensors, connectivity, motors, and lighting — and shows how small ideas can scale into polished, professional outcomes.

You also see how to build smaller, related examples using the circuits and sketches covered throughout this book. Chorus Chorus was a kinetic light and sound installation by United Visual Artists (UVA), a London-based art and design collective. The piece consisted of tall pendulums swinging in perfect synchrony, each fitted with lights and speakers that filled the » Exploring iconic Arduino projects from art, design, and industry » Understanding how each project worked and why it mattered » Finding inspiration for your own creations using examples from this book 152 PART 3 Building on the Basics space with rhythm and movement.

(See Figure 8-1.) Visitors could walk beneath the pendulums as the pattern shifted from chaos to calm, creating a mesmerizing, immersive experience. How it works Each pendulum contained an Arduino that controlled motors, lights, and sound. The swing motion came from a motor and reduction gearbox, which the Arduino triggered through a relay circuit. Every pendulum also had custom LED boards and a speaker in its base. The Arduinos communicated with custom software that syn- chronized all the movements to a musical score composed by Mira Calix.

The setup demonstrates how a single board can coordinate multiple outputs — light, sound, and motion — while responding to real-time instructions from a central controller. Lessons learned » Arduino can scale up to large, coordinated systems when combined with solid engineering. Chorus in full swing. Courtesy of United Visual Artists CHAPTER 8 Learning by Example 153 » Simple circuits (LEDs, motors, relays) become powerful when used in repeti- tion and synchrony. » Collaboration between artists, programmers, and engineers creates experi- ences that none could achieve alone.

Build your own You can experiment with similar principles on a smaller scale using servos, LEDs, and an Arduino Uno R4.
