This Fall, 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 my fifth project, 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.
