Using the LittleBits Fork Bit is easy. First, locate the output of a single Bit. Then, connect the Fork Bit to this output. You can then attach up to three other Bits to the Fork Bit. This is great when you want to make different things happen at once, like having a light flash, a sound play, and something move all at the same time. As for maintenance, keep it in a dry place and away from dust. When not in use, store it with your other LittleBits to keep everything organized. There aren't many special things to watch out for, just make sure the connections are secure when you're using it.
