Four Fun
Build the circuit as shown, and turn on
the slide switch (S1). The four LEDs light
in a blinking pattern, but some will be
dim. You can swap the LEDs with each
other and see how the circuit changes.
You can also remove one LED, or
replace one with the melody IC (U32).

This circuit has two pairs of parallel LEDs in series
with each other. Some of the LEDs are blinking
in different patterns (D11 turning on and off, D8
changing colors quickly, and D12 changing colors
slowly). Red color is easier to produce than green
or blue, and green is easier to produce than blue.
The combination of these effects creates the
pattern you see.
