The Audiono Spectrump Analyzer takes in input from a headphone jack or dongle on phones, computers, or other devices, digitizes the data using the MCP3004 ADC, using SPI to communicate with the ATMEGA328P. Then, using a fast fourier transform, the time domain data is converted into frequency domain data, before being outputted to an LCD display, also using SPI.
