A what?A trimmer
One second is a long time, though.
Yep. I'd say at the very least 2/3 of a second.
Are you referring to the Arduino (no, it's fine), or the wallwart (it's likely fine, too)?
I was referring to the ATmega328, as the subject line reads. So if it(the atmega) is ok then thats good news. Thanks.
