Game and Knowledge in Electronics-Lab
To start the first programme, you need to connect connector A with
connector B. The loudspeaker also needs to be connected. It has
two connectors, SP1 and SP2, which must be connected with the
connectors MS13 and MS14 of the micro-controller. The abbreviation
SP stands for SPeaker. As soon as you have connected the battery,
you will hear a clear sound.

A sound from the micro-controller
Turn the micro-controller module
around and you will see a board
with a black spot on its back,
which protects the actual micro-
controller. It consists of a small
silicon disc, which is also called
chip. It contains many very small
components. They are mainly
transistors, which are connected
in complex circuits for different
tasks. Some of them create
sounds and are connected
to the connectors MS13 and
MS14 where the loudspeaker
is connected. Every time you
use the loudspeaker in an
experiment, it is connected
exactly here. The same is true for
other modules, which are always
connected to exactly the same
connectors. You will know these
connectors precisely after doing
a few experiments. You will know
where you can connect an LED, a
switch and a potentiometer.
You can find many other
components on the board. Most
of them are resistors (R1, R2...).
They protect the micro-controller
by limiting the current. Should
you make a mistake, you won’t
damage everything. There are
also some silicon diodes (D2,
D3...), which let electricity flow
in only one direction just like
light-emitting diodes. They also
help to prevent certain errors
and protect the micro-controller.
There are also many capacitors
(C4, C5...), which are important
for interference resistance and
different other tasks.
