This device detects an intruder with the light sensor.
The alarm requires the tricolour LED and
the loudspeaker. The programme is started with
the connection B-H.
The motion detector works best when the light isn’t too bright. Place
the sensor in a location where it will be in the shadow of an intruder.
Try it for yourself and see if the alarm is triggered. You will hear
a loud siren and coloured light flashing.

Often a decision is made by tossing a coin.
Which side is on top, heads or tails? This
device gives an equally random result. You
will need one button, the tricolour LED and
the loudspeaker. Every time the button is
pressed, the coin is tossed and the result is
red or green. To start the programme you
need to make two wire connections, A-B
and C-G.
