Depending on the input, the output signal of each container varies. The MSGEQ7 is a 7 channel spectrum analyzer chip that divides the input signal into 7 different frequency containers. Each frequency is used to drive the clock of a spectrum chip MSGEQ7. The Arduino uses a frequency board SI5351 to generate two stabile different frequencies. The main circuit evolves around an Arduino Mega 2560 ( Pro version preferred because of the smaller footprint). There are two microcontrollers involved but one is optional because it is used for a flashing logo only.
