C Programming for Arduino

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

Chapter 9. Making Things Move and Creating Sounds

If the Arduino board can listen and feel with sensors, it can also react by making things move.

By the movement concept, I mean both of the following:

  • Object movements

  • Air movements producing sounds

We are going to learn how we can control small motors named servo, and how we can deal with high-current control by using transistors.

Then we'll start talking about the basics of sound generation. This is a requirement before trying to produce any sounds, even the simplest ones. This is the part where we'll describe analog and digital concepts.

At last, we'll design a very basic random synthesizer controllable using MIDI. We'll also introduce a very nice library called PCM that provides a simple way to add sample playing features to your 8-bit microcontroller.
