// Small sketch whichs let's LEDs make blink blink blink ...
// How it works: Just create a light object with "Create" and put an "Init" into Setup() and a "Check" in Loop().
// After on_1 ms the light is turned off, then after off_1 turned on again. You can define up to
// 2 periods. Each light gets its own counter, so you don't need to compute divisors or counters. I'm using JeeLib
// for the MilliTimer.
