12v Power Supply Reduction

Hello, I have a 12 volt 2Ah battery and i wish to power my arduino mega without damaging it. do you have any idea what i can do. Thankyou.

The Mega accepts 12V input, just connect it up....

The current is what i am worried about. is 2Ah ok?

Current is drawn by the using device, not imposed by the source; so it won't "flood" the Arduino, the Arduino will take what it needs.

By the way Ah aren't current, they are capacity. So 2Ah could mean 2A current for an hour, or 2mA for 1000 hours, or 4A for half an hour..... who knows?

It's very lucky that it does because there's a gigawatt power station connected to my PC right now.

(But it's a good thing they step the voltage down by the time it comes through your wall eh? )

Remeber it's the amps that kill not the voltage lol

Stepping down the voltage steps up the amps...!
