Arduino & Co – Messen, Schalten und Tüfteln

With a simple Arduino Pro Mini board and a few additional components, it is now possible to realize projects for little money that would have been unthinkable or cost a small fortune 20 or 30 years ago. This book includes a variety of projects, from simple LED effects to a charging station that thoroughly tests the battery. The ATmega328 microcontroller serves as the core for all described projects, offering countless possibilities for measuring, switching, and controlling with its 20 input and output pins. For example, with a 7-segment display and a few resistors, you can build a voltmeter, or use an NTC to create a thermometer. The Arduino platform provides the perfect development environment for programming the boards. In addition to specific projects, the book aims to impart the necessary knowledge to realize your own ideas. How do you measure what? Which transistor is suitable for switching various loads? When is it better to use an IC, or how do you switch mains voltage? Battery-operated projects with LilyPad are also thoroughly discussed, as well as various motors, from simple DC motors to stepper motors. Sensors are another exciting topic. Just two examples: A tiny component can actually measure that the air pressure at floor level is higher than at table height. With a simple infrared receiver, you can give old remote controls a second life and use them to control your home.
