Bits modules with blue connectors are the ones that provide the juice to get you up and running! You’ll need one of these Power modules in every creation you make.
Input Bits modules are pink. They are buttons, switches and sensors: the eyes + ears of the system. They interpret their surroundings to make things happen.
Orange Bits modules are Wires that help you extend + branch out. You don’t always need one, but they give you options for linking and adding intelligence to your creations.
