1 The components
This package contains exciting projects with LEDs and other
electronic components. In addition, there are info boxes all
around that explain why the experiments work the way they
do. Of course, you can also just perform the actual experi-
ments. After a while, the technical connections will become
clear on their own!
The package contains the following components to build
and connect: a plug-in board to assemble all the tests, a 9 V
battery clip to connect the battery, a dual four-port switch, a
two-wire fuse, and five cables to plug into the plug-in board.
The battery cable must be fixed as stable as possible, so that
it does not come loose during the following experiments. The
bare tips of the red and black cables should be plugged into
