The split lets you connect a single Bit to two other Bits. If you place an input before the split, it will control the two outputs at once, like a single light sensor controlling two motors to spin car wheels. The flexible wires on the split also allow you to place your Bits further apart and position them how you like.The split is perfect for logic gates where you need two inputs. You can use it like a wire Bit if you ignore one of the connections. Each wire on the split is six inches (15 cm) long.
