Build the circuit as shown, and turn on
the slide switch (S1). The three LEDs
(D8, D11, & D12) light in a dim blinking
pattern, and the melody IC (U32) makes
weird sounds Try removing one of the
LEDs at a time and see how the sound
changes.
Electricity from the batteries goes through
the melody IC, then splits up and goes
through the three LEDs, then re-combines
in the switch. The LEDs all having dierent
blinking patterns and the melody IC has a
sound pattern; their combination creates the
eects you see and hear.
