We can say that in this serie we will give to the readers the opportunity to have in their tablets, iPhones, iPads and PCs a powerful source of ideas for projects and informartions. Microcrocontrollers such as Arduino, MSP430, PICs and others can´t source a large amount of current to loads like motors, relays and lamps. They also can´t work with signals sourced by some types of sensors plugged to their inputs. In these cases they need special ads, circuits to allow the use of power loads and sensor. These circuits are called shields. This book is a collection of 100 circuits of shields including drive to high current loads, motors, sensor, to produce audio signals and much more.
