Hello, I’m doing a sort of lantern,
I’m using 8 leds 5mm connected arduino digital pins.
but for every pin, I connected 2 leds, I mean use, only 4 digital pins.
I want to use this battery Portable Power Bank Mobile Charger 5000mah [/ b]
As the duration of the battery?
if I use an Arduino Uno or Arduino Pro Mini 328 - 5V/16MHz, or an arduino nano,
change the input voltage from arduino?,
I have seen some of these operate at 5v, 7v others, so this battery will not work for some Arduinos.
Am I wrong?
The Arduino Pro Mini 328 - 5V/16MHz, is the only one that works 5v (Vcc) and also has a regulated entry of (5v-12v)
which I use and recommend baeria use?
the advantage of this battery, battery charger traee built.
Thanks for your attention!
