Quick Steps

  • Install ezOutput 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 ezOutput 03.SingleBlinkWithoutDelay example
/* * Created by ArduinoGetStarted.com * * This example code is in the public domain * * Tutorial page: https://arduinogetstarted.com/tutorials/arduino-output-library * * This example blinks an LED 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(500, 250); // 500 milliseconds ON, 250 milliseconds OFF } void loop() { led.loop(); // MUST call the led.loop() function in loop() }
