The aim of this game is to shake the location
sensor connected to two long cables as fast
as possible. Your micro-controller will count
the number of moves for ten seconds. Use
the longest cables to connect the sensor.
You will also need the loudspeaker and the
tricolour LED. The counting programme is
started again with two wire connections,
A-C and D-G.
The game starts as soon as you connect
the battery. You will first hear a
countdown of three identical
tones and a start tone. Then
you start shaking. The sound
of the ball inside the location
sensor tells you the best
movement direction. After
half the duration, you will hear
more tones that count the last five
seconds. At the end, a long tone
is played and you know that the
time is up.

Shaking record
The result will be shown with the tricolour LED. The red
LED shows the tens, the green LED the ones. If the red
LED flashes three times and the green LED five times,
the result is 35. Write down this number. Everybody
thinks that they’re faster, must prove it. To re-start the
game, you need to disconnect the battery cable and
re-connect it.
