The XOR Bit is a logic gate with 2 inputs. Think of it as "exclusive or," meaning that it sends an ON signal when it’s receiving an ON signal exclusively from 1 input or the other, but not both.

The XOR Bit is a logic gate with with two inputs and one output. In order for the XOR gate to output an ON signal, either one of its inputs, but not both, are ON. The XOR is called the "exclusive OR" Bit because it is similar to the OR gate, but only outputs a signal when one input is ON at a time. Building circuits with logic Bits is essentially the equivalent of physical prograqmming. Logic Bits create rules for your circuit to follow, giving you more ability to create interesting and complex interactions. The XOR is great for projects in which the activation requires input alternation.

Anytime the XOR receives a signal lower than 2.5 volts at both of its inputs at the same time, the XOR sends an OFF, or 0 volt signal, from its output. If the XOR receives a signal greater than 2.5 volts at either of its inputs, the XOR sends an ON, or 5 volt signal, from its output. If the XOR receives a signal greater than 2.5 volts at both of its inputs at the same time, the XOR sends an OFF, or 0 volt signal, from its output. Logic Bits like the XOR only work with two states of inputs, ON and OFF. When an input is either ON or OFF, like a button, a toggle switch, or a sound trigger, we call it a digital input. Inputs that have variable voltage like pressure sensors, dimmers, and light sensors, are analog inputs. Because logic gates only deal with ON/OFF, high/low, or true/false, analog signals pass as digital. With analog inputs, an “ON” signal occurs at about 2.5 volts when passing through a logic gate. Also in logic circuits, you may want to hold the state of a momentary input (like a button). In order to hold this state, you can use a latch. You can also use a timeout to hold the state for a certain period of time.
