Hello Microphone Board
The purpose of this board is to take microphone input and display it visually using a python program when the board is connected to a computer via a FTDI cable. For whatever reason, I found that the non-fab inventory microphone I used only picked up high pitched electronic noises / music. The microphone / program did not display input from sounds in a lower range or general music or background noise.
