A sound sensing system using NodeMCUs and Websockets

This system is a flashing LED TV backlight that contains a sensitive mic sensor that allows the LED lights to dance to the music tempo. The device uses a mic sensor as an input as it receives the sound signal and inputs a signal into the microcontroller (Arduino Nano). The microcontroller outputs bits (0 = 0v or 1 = 5v) depending on the frequenc…
