Am I able to plug into my arduino a battery that is rated higher than 5 volts?
I mean, Ive seen arduinos with a 9-volt battery hanging off of them before, but what I have in mind is actually a cordless drill battery.
A cordless drill battery would be sufficient enough to power the arduino and drive a solenoid I am wanting to use.
How can I make my arduino be powered by a large battery (16v) without frying the board? Can I just plug it in and not worry about it?
