Why would you want to look at those tiny led displays or those small LCD's if you can do it big?
14 Channel spectrum analyzer with 280 acrylic leds (WS2812) controlled by Arduino
40Hz - 16Khz Line in / Microphone in
Different modes and colors
Brightness / Sensitivity / Peak delay control
*Key components:* Arduino Mega 2560 Pro Si5351A breakout board WS2812 (74Leds/meter) Acryl 10mm You will need access to a laser cutter to cut out all 280 acrylic Tiles Although the design of Acryllics, PCB, hardware and modification of firmware is all mine, the idea and original firmware that I started with should be credited to PLATINUM.
A Video of the working setup is here:Check out the complete List of materials at my Github!
*Project download: * All hardware, software etc. is "as is" and you are free to modify it to your needs. None of the hardware has been tested for CE compliance etc. If you decide to use anything from this design, you do so at your own risk. Coding, PCB and drawings are all available for download. PCB ( no components included) is available but I only ship within Europe. Send me a message or email me at email@example.com if you are outside europe and are in need of a PCB.
