I am going to build a VU meter based on the following schematic by audioguru:
vu meter schematic
I took it from this post.
My knowledge about electronics is very limited but enough to be able to actually convert this schematic to working project.
I have two questions though:
1. Is there a way to add switch to pin 9 to enable dot mode on the LM3915 or schematic would have to be redesigned?
2. If I want to connect two LEDs to each channel (in series) so my VU meter is brighter, would that work without making any changes?
Thanks.
