this includes a debounce:

Pushbuttons often generate spurious open/close transitions when pressed, due to mechanical and physical issues: these transitions may be read as multiple presses in a very short time fooling the program. This example demonstrates how to debounce an input, which means checking twice in a short period of time to make sure the pushbutton is definitely pressed. Without debouncing, pressing the button once may cause unpredictable results. This sketch uses the built in millis() function which keep track of the time passed since the the sketch was run and by extension since button was pressed to stabilize the output .https://www.arduino.cc/en/Tutorial/Debounce
