/**13x WS2812B or WS2812 controllcode by marderchen =^.^= used vor mouse illumilightly.. connected 3 moustasters to PA0-2
 * (the stasters witching the 2V comes out frome optical module to ground so bridge PA0-2 to 3V3 if no tasters or remove or replace istinput(); with zufall(); in loop)
 * (4WS2812 first 4 one right, 4-8 left, 8-13 middle, fist led right near wire, last led wheel(layed in spiral)
 * required capacitor for stabilize power (have used 6.3V 1500yF for 5V and 6.3 1000yF on 3V3 on STMF103C8T6 (the on 3V3 not realy needet, just for savety)
 * used mouse: PO2361 MAXXTER Gamming mouse caused 6buttons , cheap with <5euro, and transparent part in case.. soldered out milky red fadingleds, and connectet STM to
 * BLACK (ground) and RED (+5V) wire from USB cable, and 3wires to the 3 taster (caused ground is same) cant use the other 3 taster caused switching not direct 5V od GND
 * ITs free! ( copy parts or use it in any kind if its usefull for you )
