SOUND FEEDBACK
This time plug the SOUND
BLOC onto the end of the FLYER so
you can move it around.
When you press the BUTTON it clicks
and this will usually trigger the SOUND
BLOC which then sends a signal to
the BLEEP. The noise of the BLEEP is
then picked up again by the SOUND
BLOC, so completing the circle.
Try to break this feedback loop by
placing a book or cushion in the way.
When the SOUND BLOC can no
longer hear the BLEEP the sound will
stop because you have broken the
loop.
Experiment with holding the
SOUND BLOC in different places
and at different angles to see
when feedback starts and
stops.
The AND block needs both
inputs to be on in order to
pass a signal on. Imagine a
farm gate which only lets the
animals through when the
farmer is there to open the
gate.
