Using the Branch Bit is super easy. First, find the output of a single Bit. Then, connect it to the Branch Bit. You can then connect up to three other Bits to the Branch Bit in different directions. This way, you can trigger light, sound, and motion all at once. When using it, make sure the connections are secure to avoid any loose contacts. As for maintenance, just keep it in a dry and clean place. If it gets dirty, you can use a soft, dry cloth to gently wipe it. That's all you need to know to make the most of your Branch Bit.
