Topic: How do I power arduino uno (Read 330 times) previous topic - next topic


I know this is a very basic question, I'm new to this stuff, but, how do I power the ardrino uno?



A few choices.

USB to any USB 2.0 port on a computer or similar.
The barrel Jack which is best to stay between 7 - volts.
The VIN pin on the board and again try stay below the 10 volt range to avoid working the regulator too hard.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.


If you search on like google there are TONS of websites out there with the basic information like that for the Arduino. I'd suggest you find a few of these getting started type websites and do some reading.  Or just look at the learning section of this site.
