Description
With a simple Arduino Pro Mini Board and a few other components, projects that were unthinkable 20 or 30 years ago or would have cost a small fortune can be realized today for little money. From simple LED effects to the charging station – which thoroughly tests the battery – there is a lot in this book.The ATmega328 is used as a microcontroller for all described projects, which offers countless possibilities for measuring, switching and controlling with its 20 input and output lines. With a 7-segment display and a few resistors, you can build a voltmeter from this, for example, or use NTC to create a thermometer. The Arduino platform offers the perfect development environment for programming the boards.In addition to the very concrete projects, the book should also provide the necessary knowledge to realize its own ideas. How to measure was it? Which is the suitable transistor for switching different consumers? When is it better to operate an IC, or how is it possible to switch on the mains voltage? Battery-operated projects with LilyPad are also discussed in detail. Equally many motors, from simple DC motors to stepper motors.Sensors are another exciting topic. Only two examples: A tiny component can actually be used to measure that the air pressure on the floor is higher than at table level. With a simple infrared receiver you can give a second life to used remote controls and control the apartment with it.
