Musical Note Detector

Allison Hong, Oliver Yu, Jessica Young

Our project detects and identifies various frequencies of musical notes through LEDs. It attempts to capture musical notes across octaves. We used a microphone as well as an op-amp buffered bandpass filter connected to an ESP32 to process the audio, with LEDs for output.

We had a hard time soldering components placed close together, as well as the ICs being tough in general.
