Circuit bench – 100 shields for arduino [EPUB ebook] 

We can say that in this serie we will give to the readers the opportunity to have in their tablets, i Phones, i Pads 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.

'Sidelights’Newton C. Braga told: 'I started to write technical articles in the Brazilian edition of Popular Electronics when I was only thirteen years old. From that time to now I didn’t stop; I have written many books and articles directed for students and professionals of electronics and such related subjects as computers, mechatronics, physics, etc.
'I also created a persona named Professor Ventura, who teaches science at the same time as he engages in fantastic adventures with his two favorite students, Beto and Cleto. In the adventures, Ventura and his students show how technical things work and give practical information to the young reader who wants to reproduce devices or experiments. The 'Stories of Professor Ventura’ are published only in Brazil.
'I write in Portuguese very fast, and when I have a practical idea I create a prototype before I produce an article. When writing in English, since it is not my natural language, I am not so fast and sometimes I need to stop to find the correct expression or word. Of course, my articles and books also need the help of a good English-language editor.
'Since the subjects I write on are technical, it is much easier to write than a novel. Electronics and the related sciences are very dynamic, changing very fast. I need to be updated with these changes when I write for publication. When I began my career, electronics consisted of radio and television. After some years it became telecommunications and then computers. Now electronics is becoming fused with mechanics and computers, resulting in mechatronics and artificial intelligence. We need to change to keep our readers.
'I think that the adventures of Professor Ventura can be used to teach technology in elementary schools since they involve high-tech devices but include explanations students can understand to the point where they can perform the professor’s simple experiments themselves. I hope to find an editor for these stories in the United States; I have over twenty 'Professor Ventura’ books published in Brazil.’
