I'm building a variable speed fan controller (tutorial at
http://casemods.pointofnoreturn.org/vregtut/) and I would like to add
an IC to display the 10 seg LED to display the level in bargraph
display. But I can't remember what part # it is! >_< I'm pretty sure
it starts with LM3xxx so can anyone fill in the missing numbers? TIA!
