in this attached file 124 page u can see scheme..
I failed my last vu meter and im newbie at electronics.. I dont even know the principle how does everything in this circuit work but i have breadboard so i think i can build this circuit... I just need help .
1 question - Will this circuit work with my lm3915 instead of lm3914?
2 question - Can someone explain how does Variable resistor and audio connects in this scheme ? And where does pin 5 go?
Thanks and i hope u can help me.. Again.. i m just a newbie so.... sry about those dumb questions
