Ludo91:
I can already read the sensors and control some outputs on Ardu (in my automation engineering class in Italy we sometimes refer to it as God Ardu, who watches you XD), my "only issues" were about speed of the whole system, seems there is enough, and how to connect the Ardu`s output to the mosfets.I am reading http://focus.ti.com/lit/ml/slup169/slup169.pdf wich is great theory explanation about mosfets.
Still, i don`t understant why logic level gate mosfets arent the right solution to "make it easy.. this is the datasheet of those i was looking at... http://www.irf.com/product-info/datasheets/data/irls3036-7ppbf.pdf
Help please XD
