1 The Experiment Box

1.1 What's inside the experiment box

1.1.1 Breadboard

All of the experiments are built on a convenient breadboard. The red lines demonstrate how the board is
wired internally. Connectors of components and any jumper wires are simply inserted into the contacts.
When finished with your experiment, pull out all the components and the wires. Thus you will have them
ready for the next new experiments. Please read our tip on "Successful equipping" in Chap. 1.2.1.

1.1.2 Transistors

One of the most important active components in modern electronics and also in our experimental package
is the transistor. It is used to amplify smaller signals and to switch currents. NPN and PNP transistors differ
in polarity, but otherwise they are the same. FET transistors have a very high internal resistance, compara-
ble to that of electron tubes, while incident light controls the current flow through phototransistors.
