* This example blinks LED:
* + blink 10 times (5 times OFF->ON, 5 times ON->OFF, interleavedly)
* + without using delay() function. This is a non-blocking example

#include <ezOutput.h> // ezOutput library
ezOutput led(9); // create ezOutput object that attach to pin 9;
void setup() {
led.blink(250, 500, 0, 10); // 500 milliseconds ON, 250 milliseconds OFF, start immidiately, blink 10 times (5 times OFF->ON, 5 times ON->OFF, interleavedly)
}
void loop() {
led.loop(); // MUST call the led.loop() function in loop()
