Intro

I alway loved music and was fascinated by it. I also love fancy rgb lights (who doesn't?) so i wrote a little c program for the attiny85. The idea was to attach a microphone and a rgb light to an attiny85, which should controll the leds in the "rythm" or "flow" of music.

The tools

To be exactly, i used the Digispark Attiny85 because of the higher clock speed. It can be easy overclocked (which you SHOULD NOT do) , but it should also work with the stock Attiny85.

§ Overclocking is only needed if you want to reach a sample rate of 1ms, which is not necessary for fluent visual effects.
The second library i used was light_ws2812_avr for the attached NeoPixel8, written by someone called Tim. So thank you very much Tim!
I used an fft-library special for the attiny which is available online, which author seems to be Tom Roberts. Thank you Tom!

The case LOL

The case is just a bad colored AP-Box i had laying arround. So nothing special.
I'm happy how the effect turned out, it responses very well to the music in the different spectra.
And yes you are right i should upload a video. I will do that soon.
The Source code is avaible at my Codebase at gitea.
