Circuit bench - 100 shields for arduino

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 an...
