External buttons are buttons which can be connected to the Kniwwelino in addition to the buttons A and B already available on the board. Similarily as for the LEDs, those are connected through the pins on the outer area.

To work with external buttons, you need additional material: the buttons, as well as wire to create a closed circuit using the pins of the Kniwwelino.

With the Kniwwelino Blocks, you can then detect when current is flowing, i.e. when the button is pressed.
