Topic: Arduino Power? (Read 1 time) previous topic - next topic


Hello, I have a question about how long I can keep my Arduino running before anything bad will happen. Can I keep my Arduino Uno on 24/7/365?

Like can I keep on feeding it 9 volts dc power 24 hours 7 days a week 365 days a year?

Yes it will run as long as you continue to pay your electric bill each month.



Ha ha thanks. I could use solar electricity, but it's just an alarm clock. Time to kill the grid! Not really that much power...

And longer still with batteries and sleeping :)

Note: Depending on what your code is doing you might run into an issue with the millis() function rolling over to zero after 50 days or so. See the following article for a description and link to solution of for the issue:
