Buton Kodu Arduino. Plug the push button in the middle of the breadboard like on the picture. Furthermore we declared a constant variable for the led and attached it to pin 10.
Here one switch press increments the value whereas the seconds switch decrements the value. It read digital output 0 or 1 from the switch and store the value. Press and keep pressing the button several seconds.
Connect one side of the 10k resistor from the ground rail on the breadboard to the other side to the pushbutton on the same side that pin 2 connects.
