FIGURE 7-6. Naming our cloudBit module
Once we have named our module, we are asked to power on the cloudBit (Figure 7-7). To
do that, we attach the wall adapter to the USB power module, and then attach the USB power
module to the cloudBit.
Note that littleBits modules have magnets on their sides, making it easy for them to snap
together with other modules. They are also color-coded. Blue-colored modules are power mod-
ules, such as the USB power module, that help power the circuit. Red indicates input; these
modules accept input from the user or the environment (an example is the button module).
These modules in turn send signals to modules that are colored green to indicate output.
These modules perform an action (an example is the servo, which is a motor that can rotate in
a particular direction). Orange-colored modules are called wires; they are used to expand the
reach of the project. An example here is the cloudBit module, which is used to provide remote
connectivity to the prototype. The order in which the modules are snapped next to each other
is important: power modules always come first, and input modules only affect output modules
that come after them.
