Arduino Smart Power Circuits

Every electronic gadget, whether hand-built or off-the-shelf, requires power. But how do you know how much power is required? And how can you build your own power circuits and converters--without frying your gadgets or yourself! Don Wilcher, the author of Learn Electronics with Arduino, shows you how to calculate power needs, build power circuits, and even use a circuit simulator so you can test before you power up. What you'll learn * What's inside a wall wart * How to built a DC to DC converter * How to calculate power and efficiency in a converter * Experimenting with a DC to DC converter integrated circuit Who this book is for Electronics and Arduino beginners who want to learn more about electrical power and power converters.
