Help with using a transistor for a beginner
Forums
I am using an Arduino and I want to power an external device. As I understand it the most I can output from the Arduino is 5v and 500ma. I need to increase this to 12v and 5a. It has been suggested that I can do this by running through a transistor.
Can anyone please advise if this is correct and what transistor I should use for this application.
Thanks, Daniel.
