 - All items in array are boolean values.
 - First item specifies if ammo counting will be detected through a switch or IR gate. `false` if switch, `true` if IR gate. Can't be both switch and IR gate.
 - Second item specifies whether or not the chronograph feature will be implemented, third for voltmeter, and fourth for select-fire.
 
 Setup IO Pins:

 - If the corresponding mode for the pin was not set up, put `-1` for the pin value.
 - First item will be pin which the ammo counting mechanism (switch or IR gate) is connected to.
