Rainbow colours

In this experiment, the micro-
controller creates a fast
flashing of the red LED with
the programme A-E. Using the
rotary knob, you can make the
flashing slower or faster. The
circuit is the same as the one
for the last experiment. The only
difference is that only the red
LED is required at output MO7.
It doesn’t matter if the two other
colours are still connected
from the previous experiment;
they will just not be used.
The controller also remains
connected as in previous
experiments.
Now also connect the third colour
by connecting MO9 with TC3.
Using the rotary knob, you can
select different colours and mixed
colours. All colours of the rainbow
and the mixed colour white are
available. But to do this, you need
to start the correct micro-controller
programme by connecting A with
F. When you have done this,
you can slowly turn the knob to
the right and watch the different
colour combinations.
