//stm kote for 25x WS2812B USB 3butons+Wheel pc mice case rainbowmod :3 (WS2812B pin PB8)
//2 additional buttons (left and right) build into case (left reduce brightenes, right more brighteness)
//5x 5mW lazers in casecover shining on roomcover powerd 3V3 GPIO direct 5Vheatresistior on cheapdiodes bridged

//powber by mice usb wire + 2 electrolyte capazitors a 10V 1000yF to reduce ws2812b pulscurrent in usb wire
//have fun :3 [MEOW] thanks to fastled lib use kote or parts of it if usefull (STM board: STM32F103C8T6 minimum system board , decompiler ARDUINO, dongle STlink-V2)
