@coitepr1

basta verificar os meus outros videos amigo (thanks to google translator) ;)

I'd like to have seen some actual VU'ing. Why not?

@2N2222A

Because it was just the first test like the description says. You could check my other videos to see the meter "in action" :)

looked fine. did you use multiple LM3915? if yes, how do display in dot mode? i am using multiple LM3915 too, but the last LED is always light. when i use multiple LM3915 by dot mode operation, i want to in the middle of 3915 to turn off the LED..

Thanks! Iam not sure if i got your question right, but my circuit only works in bar-mode because the voltage-ranges of the 3915 are "overlapping" in order to obtain a 0,6dB resolution. (not only the 3915's native 3dB per step)

Nice job!! Cool!!

Hi, I have also the same LED bars, but is there a (nice)way to build these LED bars in a frontplate? Do you have any hint for it?

Thanks,

Erwin.
