That is why I stated Quoteexcept most recommendThis is a pretty controversial topic (gate resistor or no for mosfets) around these parts and both parties make a decent case for their point of view. I have mostly not used a series base resistor when driving mosfets with arduino output pins, but then I'm a quick and lazy type that just wants to get some electrons flowing. I'm of the belief that the AVR output pins are pretty husky devices that can take some abuse. But then again I just build hobby projects not selling commercial offerings, so long term reliability is not a high priority for me.Lefty

It is a 10K? Brown Black Orange.If you turn off the Arduino with the circuit in-tacked, what happens?Why would you want to disconnect the controller (Arduino) from the driver with driver power still on?For others you may want to review: http://www.electronics-tutorials.ws/transistor/tran_7.html
