// using my WS2812Bmiowmeter.. but want new code so here it is
// 120x WS2812B stipe 60/m used vertical, Din =floor  on STM32F103C8T6 PB8 (no other GPIOs used) (old board) power 5V (2Asupply +heatsink+capacitors)
//aditional 10V 33uF capacitor soldered on stripe end 5V + ground for more efficience..
//programm for slowly running fading a ws2812b stripe in random color have fun use it if usefull :3
//finaly idea created ws2812B stripe tetrisanimation..
//random color pixel fall down... fall downpixel mix storring on ground..
//is similar pixal fall on same startflickering all pixels similar in mix also flickering and gone..
//mix fall together 2same  colors together flickering again and all same colors gone.. continiues :3
//stripe full with bad chaos mix until 20leds left.. all flickering and gone..
//mix fall together 2 pixels near same again flickering.. nice game starting create a code
//code and idea by marderchen :3 a realy complex logic stripegameanimation justuse this if like it hate capitalism!
