LM3915 IC VU Meter Tower

This was based on an LM 3915 IC and also worked well with an LM 3916 IC. These were bought through eBay Built using 10 - 10mm thick plexiglass sheets purchased precut to size (5“ x 6“), 20 LED’s (9 colors) wired in parallel for the plexiglass sheets and the arrays also wired in parallel and a 6V DC 1A adapter to power the project. Base of the project was just a wooden frame with some plexiglass added for a top and front panel. Here’s the basic circuit I used.
