However, we know that not everyone has as
sophisticated a sense of humour as we do, so we also
include the product description below if necessary.
It has not been known for a long time that the alarm
alerts, the painter paints and the resistor puts up
resistance. So, if one day someone were to ask you
what the Colorophon actually does, the answer is
childishly simple - the Colorophon colours :)
The colorophone catches the surrounding sounds and,
depending on their tone, frequency and intensity,
lights up in a quite different way for each sound. The
application of this smart device is much more
interesting than it might seem.
It is not only useful for partygoers, musicians and
audiophiles - there are many more options. From rave
parties (or indeed all parties), to signalling to children
that they are too loud, even to checking who is
snoring in what key. Referring to the above
description, virtually countless other possibilities for
the use of our Colorophone come to mind.
Of course, the most essential function of our EDU kit
is the opportunity to develop passion and soldering
skills.

Components received in the kit, may differ in appearance from those shown in the photograph. Despite this, they
have the same parameters, and their appearance will not affect their operation in the unit.

Figure 2 shows the layout of the components on the
PCB.
Solder the components sequentially onto the board,
starting with the smallest ones. Once the system has
been mounted, very carefully check correctness of
installation. Check that the components have not
been soldered in the wrong direction or in the wrong
places and that no soldering points have been short-
circuited during soldering. The sensitivity of the
Colorophone can be adjusted using potentiometer
PR1.
