but we'll only use C in the examples below. In Arduino programs, called Sketches, you essentially write code to set up your Arduino for a specific tasks or tasks, then run a continuous loop which ...

You can read the state of a button using Arduino ... 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 pressed.

The Arduino ... code in loop() can be extracted into a function, outPins, and the duplicate code can be manually replaced with a call to the new function. Not an earth shaking example, admittedly ...

We'll outline the basics of the Arduino itself, what the crazy jumble of wires means, and then step through how to use other people's code and schematics to build your first electronics project ...
