Im working on an arduino project that just simple has to be self contained and mobile. I can share the details in anyone cares. the issue at this point is how to power it mobily (battery)
I consider myself a novice, but have a pretty good grasp on battery power. I have changed out the UNO for a mini to help the power draw.
The issue consists of this:
#1 the main sensor of my project draws “<750mw”
#2 I have a 5v voltage regulator feeding it all.
So I need a battery solution that can feed min of 7v to power the voltage regulator.
my first idea was to power it all off a disposible 9v. Knowing the mah rating sucked I tried anyway and it only lasted about 20 mins or so. LOL.
can anyone help recommend a decent mobile power solution?
