Is it possible to use PWM on Arduino to control the voltage of an external power source? http://www.instructables.com/answers/Is-it-possible-to-use-PWM-on-Arduino-to-control-th/ http://www.instructables.com/static/defaultIMG/default.SQUARE2.png http://www.instructables.com/static/defaultIMG/default.SQUARE.png http://www.instructables.com/static/defaultIMG/default.SMALL.gif Shizen Let's say I want to vary the speed of the motor that operates at 12V.
