Make: Getting Started with Netduino

Start building electronics projects with Netduino, the popular open source hardware platform that's captured the imagination of makers and hobbyists worldwide. This easy-to-follow book provides the step-by-step guidance you need to experiment with Netduino and the .NET Micro Framework. Through a set of simple projects, you'll learn how to create electronic gadgets---including networked devices that communicate over TCP/IP. Along the way, hobbyists will pick up the basics of .NET programming, and programmers will discover how to work with electronics and microcontrollers. Follow the projects in sequence and learn techniques for building your own Netduino-based devices. * Get an overview of the Netduino microcontroller family * Install the free Visual Studio Express, .NET Micro Framework, and Netduino SDK * Write code that lets you turn Netduino's LED on and off * Learn how to increase Netduino's capabilities with various expansion shields * Measure digital and analog inputs with MakerShield * Make a light appear dimmer or brighter with Pulse Width Modulation * Use electrical pulses to play a song and control the position of a servo motor * Create an app to control your Netduino over the Web Contents 7 Preface 9 What You Need to Know 10 How to Use This Book 10 Conventions Used in This Book 10 Using Code Examples 11 Safari庐 Books Online 11 How to Contact Us 12 This Book Was Made Possible By 13 Chapter聽1.聽Introducing Netduino 15 Meet the Netduino Family 16 What You Need 20 Chapter聽2.聽Setting up the Free Tools 23 Step 1: Install Visual Studio Express 24 Step 2: Install the .NET Micro Framework SDK 26 Step 3: Install the Netduino SDK 27 Conclusion 27 Chapter聽3.聽First Projects 29 Start Visual Studio 29 Blinking the Onboard LED 30 Running the Blinky App 33 Pushing the Onboard Button 35 Conclusion 38 Chapter聽4.聽Expansion Shields and Electronic Components 39 A Gallery of Shields 40 Motors 40 GPS 41 Wireless Networks 42 Graphical Display 42 Breadboards and Components 43 Conclusion 46 Chapter聽5.聽Digital and Analog IO with the MakerShield 47 Pushing the MakerShield鈥檚 Button 48 Analog Inputs 52 Measuring Voltage 52 Other Analog Sensors 56 Conclusion 56 Chapter聽6.聽Breadboards and LEDs 57 Changing Intensity 57 Setting Up the Breadboard 58 Hooking Up the Components 58 Writing the Dimmer Code 61 Mixing Colors 63 Conclusion 66 Chapter聽7.聽Sound and Motion 67 Making Music 67 Motors and Servos 73 Servo Control 74 Conclusion 77 Chapter聽8.聽Connecting to the Internet 79 Coding the Server 79 Conclusion 86 Appendix聽A.聽Upgrading Firmware 87 Minor Updates 87 Major Upgrades 90 Appendix聽B.聽Developing Netduino Apps with Mono 93 Prepare the Netduino 93 Set Up Your Developer Tools 94 Install Mono 94 Install Mono 2.10 94 Compile Mono 2.12 with Mono 2.10 94 Install Wine 95 Download Supporting Binaries 96 Compile an App 96 Start building electronics projects with Netduino, the popular open source hardware platform that’s captured the imagination of makers and hobbyists worldwide.
