pinMode(BUTTON_PIN, INPUT_PULLUP); }This is how you initialize the push button in your code. In the void setup(), you use the pinMode() function with 2 arguments: first the button’s pin – here BUTTON_PIN will be replaced by “4” – and then the mode we want for the pin....

Note:Actually, our pushbutton requires just a bit more code: we need to declare an input property for the color, using the@property()decoractor (and with a default value of red), and paste the SVG code into ourrender()method, replacing the color of the button cap with the value of ...
Before you can send the code to the board, it needs to be converted into instructions that can be read and executed by the Arduino controller chip; this is calledcompiling.To do this, click the verify/compile button (the top-left button with a checkmark inside), or select Sketch→Verify...
