#include <ezButton.h>
ezButton button(7); // create ezButton object that attach to pin 7;
void setup() {
Serial.begin(9600);
button.setDebounceTime(50); // set debounce time to 50 milliseconds
}
void loop() {
button.loop(); // MUST call the loop() function first
int btnState = button.getState();
Serial.println(btnState);
if(button.isPressed())
Serial.println("The button is pressed");
if(button.isReleased())
Serial.println("The button is released");
