/*
Simple demo of using all the timing helpers elapsedMillis makes available.
Code from https://github.com/pfeerick/elapsedMillis/blob/master/examples/blinkingLeds/blinkingLeds.ino
Modified to test the rollover of elapsedSeconds.
Wokwi: https://wokwi.com/projects/402859003988453377
See https://github.com/pfeerick/elapsedMillis/issues/16
Either attach LEDs with series resistors to the indicated pins, or a
six led / six bit 'Chartreuse' module plugged into pins 8 through GND.
Wired up in order, the leds have a nice walking/counting effect.
This example code is in the public domain.
