Hi folks, I've got an arduino nano (Elegoo brand) that I've connected to 5 LEDs. The goal is that 4 of these LEDs will flicker/fade, and the 5th LED is steadily on. I got this configuration working, with the USB cable plugged in. For my project (space is limited), I need to run it off of a battery…

Powering LEDs when using Vin w/battery (Arduino Nano)

I think PaulRB is 100% correct. You must consider the current, not just the voltage.
