So I recently bought LEDs strip and decided to play with it. I wanted to make a music reactive LED strip but most of the projects I found were using sound sensor.
I didn't want to use sound sensors so i searched and found someone who made it using python script to send data over serial port.
So I inspired myself from his code and made some modifications. I know it is not perfect but it works and it's pretty cool, so feel free to play with it and improve it !
I'm using Adafruit Neopixel 144 LEDs 1m and FastLed library. You can see the code on my github
