Hi! I've read all the description of the arduino-sensor system to measure dc produced by a small windmill. i'd like to know how you wire the circuit to the turbine. I mean: in this schematic http://openenergymonitor.org/emon/sites/default/files/DC01.png you create a voltage devider with the RVDa and RVDB resistors, but what about the op-amp and the transistors?? why do you use them? and how do you get the voltage from the windmill??
