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 08.Pulse example
/* Created by ArduinoGetStarted.com This example code is in the public domain Tutorial page: https://arduinogetstarted.com/tutorials/arduino-output-library This example create a high pulse when a button is pressed */ #include <ezButton.h> // ezButton library https://arduinogetstarted.com/tutorials/arduino-button-library #include <ezOutput.h> // ezOutput library ezButton button(7); // create Button object that attach to pin 7; ezOutput led(9); // create ezOutput object that attach to pin 9; void setup() { button.setDebounceTime(50); // set debounce time to 50 milliseconds led.low(); } void loop() { button.loop(); // MUST call the loop() function first led.loop(); // MUST call the loop() function first if (button.isPressed()) { if (led.getState() == LOW) { led.pulse(1000, 250); // 250 milliseconds delay, 1000 milliseconds HIGH pulse } } }
