NOT Gate

 is a logic control device that inverts the input signal.

Properties
A Not Gate is a kind logic control device. Logic controls are used in electronics and are switches that when a signal is placed on the inputs if they meet the right conditions will put a signal out on it's output on the otherside.

In Logic control devices there is two binary option a signal can carry to the input the device, it's ether :  1 = ON or HI signal     or it's a 0 = OFF or LOW signal. It does not pass anymore information or a voltage through the one directional device, just a HI or LOW signal.

The NOT Gate purpose is to invert the signal that is put on the input of the device.

In-Game Description
Generates a signal if its input (bottom-left) is 0.
