Hi, I'm trying to figure out how can i use arduino to display(on small LCD) battery capacity left in my 3.7V lithium poly battery(like 30% or in bars) which is being charged by solar panel. I'm new to microcontroller so please if anyone can help. Thanks

It's easier to do it on an LCD than on an LED bargraph.
