The Arduino sketch continually reads an input pin using an internal pull-up resistor to make it logic high with the key switch connecting the signal to ground.

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the … ...

C ‘common sense’ is that the switch/case answer is both faster and makes more compact code because compilers tend to convert these into a jump table. However, the Arduino compiler tends to convert ...
