Gator:control ProtoSnap Hookup Guide

Hardware Overview
The gator:control contains four boards in the main assembly, all of which can be broken out of the main board for individual use. Buttons or switches allow you to create a point in a circuit that can either be closed (connected) or open (disconnected). Most buttons, including the ones on the gator:control, will be a closed circuit only when they are being pressed. These buttons on the gator:control are highlighted below.
The second type of control element on the gator:control is the slide switch. This will be a closed circuit when the switch is in the ON position and an open circuit when the switch is in the OFF position. The slide switch is highlighted on the gator:control below.
The final type of control element is the reed switch, which is controlled by a magnet. The reed switch will act as a closed circuit when you bring a magnet sufficiently close to the switch. The reed switch is shown highlighted in the image below.
