XOR Gates are used in creating logic gates. XOR gates have multiple inputs, and the amount of inputs are customizable up to a hundred. When only one of the inputs are active, the XOR gate triggers what the output is connected to. The XOR gate is also the counterpart of the OR Gate.
Basically, this gadget activates when only one of the inputs attached to it are active.
When the XOR gate has only one input activated, the XOR gate will output the analog value of the activated input.
