How to use button to start program?

How to start Arduino program by pressing a button.? I want to run Arduino code when I press a button.
Answer

See and compare two below codes:

void setup() { /******************* * your setup code *******************/ } void loop() { /****************** * your loop code ******************/ }

#include <ezButton.h> ezButton button(7); // create ezButton object that attach to pin 7; void setup() { button.setDebounceTime(50); // set debounce time to 50 milliseconds while (!button.isPressed()) button.loop(); // MUST call the loop() function first /******************* * your setup code *******************/ } void loop() { /****************** * your loop code ******************/ }
