That would drop the 3 volts 1 and a half volts on the high end, putting it in the voltage range of the flag. I think this will work.<VAR id=yui-ie-cursor></VAR></SPAN></div>

<DIV id=yiv2084701691>Justin a voltage divider will work but you need to the current that the flag motor takes
<DIV>vin -> R1 + R2 -> gnd </DIV>
<DIV>vout from junction of R1 + R2</DIV>
<DIV>ohms law</DIV>
<DIV>E/(I * R) if you know two you can solve for the other</DIV>
<DIV>enjoy </DIV>
