Hello everyone, I'm new here and wanted to ask for some help with an upcoming project of mine. I want to make a vu meter that looks like this (http://www.youtube.com/watch?v=_UDw6NOazt0).
However, all of the diagrams I've found seem to have people saying they don't work or this and that should be changed. So I want to ask people who have dealt with this IC first hand so I know what to expect and so on.
I would also like it to be ran in dot mode and not the bar mode. I know bar mode can be turned up by connecting pins 9 and 3.
Here's the specs of the IC (http://www.ti.com/lit/ds/symlink/lm3915.pdf)
Thanks
