Controlling LEDs using music is an exciting way of adding to the atmosphere, be it with frantic gated strobe lights or subtle glacially evloving backgroud hues. The Shades Audio Sensor Mic + MSGEQ7 Spectrum Analyzer is a great product to get started in the world of the former, designed for audio reactive sunglasses for all your raving needs – with opportunities for bold scrolling text and colourful flashing lights aplenty.
The board itself can be attached to LED Matrix shades or RGB Shades (set by fitting a jumper) and uses a built-in microphone to analyse incoming audio across the frequency spectrum – outputting the data as a spectacular light show! It’ll send varying voltages to LEDs which correlate with the dynamics of the music – meaning ambient jams behave slowly and high-octane hardcore techno, quite the opposite!
This latest version comes with a gain switch for high and low sensitivity,with a world of options for display output provided on their documentation pages found here: Shades Audio Sensor. There’s even an example of using the board without the glasses available there too, which could come in handy if you don’t want strobe lights attached to your head!
