#include <ezLED.h> // ezLED library
ezLED led(9); // create a LED object that attach to pin 9
void setup() {
Serial.begin(9600);
led.blink(250, 750); // 250ms ON, 750ms OFF, blink immediately
//led.blink(250, 750, 1000); // 250ms ON, 750ms OFF, blink after 1 second
}
void loop() {
led.loop(); // MUST call the led.loop() function in loop()
if (led.getState() == LED_BLINKING)
Serial.println("BLINKING");
else if (led.getState() == LED_IDLE)
Serial.println("BLINK ENDED");
// To stop blinking immediately, call led.cancel() function
