We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is connected to pin 2 using the resistor in series with it. In the setup() function we set the ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

Meanwhile, the reset button is just that — to reset the board to its initial state. As for the pins, the UNO features 14 digital pins for both input and output use, six analog pins for input ...
