| - | **Pull-Down Resistor:** In this lesson we will use a Pull-Down resistor to make sure we can reliably detect button presses. If an I/O pin is 'left floating' reading it's value can result in either HIGH or LOW. By attaching a resistor between the I/O pin of the Oak and GND we can ensure that if the button is not pressed, the state is always LOW. | + | **Pull-Down Resistor:** In this lesson we will use a Pull-Down resistor to make sure we can reliably detect the tilt switch tilting.
