I'm sorry if this is a newbie question or if someone else has posted something similar but i cant find anything.
As the title states, I need to power a fan which requires 12 volts as well as other components such as a transistor, potentiometer and led. The problem is that I can't use the fan at max power since there is not enough power. Is there any way to increase the voltage input without frying the arduino or some other way I can improve power efficiency?
Again, sorry for the newbie question
