Sorry for the newbie question, any advice is greatly appreciated.
I have a 9V battery holder that I am using to power by Arduino Uno. Is it possible to replace a regular 9V with one of the Lithium 9V that are made for smoke detectors (longer lasting)?
Spec link Below. If anyone has the time to check it out, I would be extremely grateful
You should do the math, how much millisamps you use as 9V even the better, don't last too long. If you need batteries, 6AA will last longer.
my 2 amps eh cents,
Yes, you could use them, but unless you’re a recent lottery winner, please don’t.
Thanks for the advice. I’m going with 6 AA.
You could also try just 3 and provide 4.5V power/ground to the power header, and not use the onboard heat generator, er, I mean, regulator.
