LengthFinder<BASE, LIGHTUP>
LengthFinder<>
Lights up exactly one led, based on the current color change variable. When changed, says what the current color change is so that you know which led is lit up. Use this when you don't know how many LEDs are in your blade. Set the blade length to 144, enter color change mode and change it until no LED turns on, go back one and there you go!
