Hello All,
I am toying with the idea of building a battery fuel gauge for a NiMH powered dive light and have found a 10 segment LED "bar graph": 10 Segment LED Bar Graph and a LM3914 driver: **broken link removed**
I am having some trouble determining if I can use the charge level of the batteries to provide the input signal or if I have to step the voltage down. Any thoughts or ideas?
Thanks for the help.
