#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
}
}
