Practical Arduino Cool Projects for Open Source Hardware- P3: A schematic or circuit diagram is a diagram that describes the interconnections in an electrical or electronic device. In the projects presented in Practical Arduino, we’ve taken the approach of providing both a photograph and/or line drawing of the completed device along with a schematic. While learning to read schematics takes a modest investment of your time, it will prove useful time and time again as you develop your projects. With that in mind, we present a quick how-to in this section | Acknowledgments More thanks than I can express go to Ann Amelia and Thomas. Their patience during this project has been amazing. Many thanks go to Hugh Blemings my partner in crime whose patient discussions during many late-night phone calls helped me understand far more about Arduino. Thanks also go out to the technical reviewers who provided us the benefit of their expertise and years of experience Andy Gelme Marc Alexander Nathan Seidle Trent Lloyd Scott Penrose Thomas Sprinkmeier and Philip Lindsay. Of course thanks go to the core Arduino team whose vision conjured the whole Arduino ecosystem into existence Massimo Banzi David Cuartielles Tom Igoe Gianluca Martino David Mellis and Nicholas Zambetti. The parts suppliers who were so helpful when it came to sourcing the random assortment of bits needed for developing these projects were also invaluable SparkFun AsyncLabs and NKC Electronics. Any many thanks go to Arduino developers everywhere The amazing success of Arduino is due to the strong community that has blossomed around it. It s a beautiful thing when imaginative people have new tools placed in their hands and the results have been inspirational to both Hugh and myself. Finally many thanks to Michelle Lowman and James Markham our editors at Apress who had to turn out of bed early to catch Hugh and I in a totally different time zone on our weekly Skype call and copyeditor Vanessa Moore who put the finishing touches on all our words xix Introduction Phenomenon is an overused and overloaded term but somehow it seems appropriate for Arduino an endeavor that has caught the attention of an astonishingly wide range of people and provided opportunities for those who might otherwise have never picked up a soldering iron or written a single line of code. From dyed-in-the-wool hardware hackers to web page developers robotics enthusiasts to installation artists textile students to musicians all can be found in the Arduino community. The versatility of the platform .
