Quick Steps

Install ezLED library. See How To
Connect Arduino to PC via USB cable
Open Arduino IDE, select the right board and port
On Arduino IDE, Go to File Examples ezLED LEDBlinkNumberOfTimes example

/* Created by ArduinoGetStarted.com This example code is in the public domain Tutorial page: https://arduinogetstarted.com/library/led/example/arduino-led-blink-number-of-times This example blinks an LED: + blink LED 10 times and then off + without using delay() function. This is a non-blocking example */ #include <ezLED.h> // ezLED library ezLED led(9); // create a LED object that attach to pin 9 void setup() { Serial.begin(9600); led.blinkNumberOfTimes(250, 750, 10); // 250ms ON, 750ms OFF, repeat 10 times, blink immediately //led.blinkNumberOfTimes(250, 750, 10, 1000); // 250ms ON, 750ms OFF, repeat 10 times, 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 }
