When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and we read a LOW. When the button is closed (pressed), it makes a connection between its two legs, connecting the...
To create a Pushbutton object with default settings, which enables the internal pull-up on the pin and interprets a high pin value as the default (unpressed) state of the button, put these lines near the top of your sketch:#include <Pushbutton.h> Pushbutton button(BUTTON_PIN); Optional...

The LED and the Pushbutton elements in action The LED is relatively simple, as it only has two output states: on and off. Behind the scenes, it uses an SVG filter to create the lighting effect. The pushbutton is more interesting. It also has two states, but it has to react to user...
