Audio Visualizer

Description

In the Fall of 2020, I challenged myself to do one PCB-based electronics project a week so I can gain more experience regarding electronics projects, specifically with layout, DFA, and BOM consolidation.
This is one of these projects, an audio visualizer! Based around an LM3914, it will compare the voltage level of the audio signal to a reference voltage, and light up a corresponding number of LEDs. There is also an audio passthrough, so you can still listen to whatever music you are visualizing.
