Arduino power.

Sorry if this is in the wrong topic...

I was wondering if this adapter would work, Here's what the label says:

AC/DC Adapter
PRI: 230 - 240V ~ 50Hz 55mA
SEC: 14V --- 300mA

EDIT: I Don't think the pin is small enough, Where Can i buy a suitable adapter for my arduino.

Yes, it works without any problem (You may notice a component an the arduino that heats a little because you are powering it with more than 12 V)

I suggest you to visit this page

14V output is a bit high. The socket can take 20 but 12 is the recommended maximum- I'd go for a 9VDC wall adapter iiwy.

Look at specs here.

The adapter pin is too big.

Do you know where I Can buy a (UK Power) adapter suitable for arduino?

The Arduino Uno can be powered via the USB connection or …

Can I power the Arduino Mega2560 via USB?

Read its specs here

Oh. Ok.

9 to 12V DC, 250mA or more, 2.1mm plug, centre pin positive.

USBs can only output a maximum of 5V... How does this work?

There's a regulator inside that takes the voltage you supply thru the jack or thru Vin down to 5V anyway... so it's all really 5V.
