littleBits XOR

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.
