Project 4 Lamp Light
Modify the preceding circuit to be this
one. Turn on the slide switch (S1) to light
the lamp (L4).
The lamp (L4) converts electricity into light. It is an
incandescent light bulb, just like other incandescent bulbs
in homes except smaller. In an incandescent bulb
electricity heats up a high-resistance wire until it glows,
producing light. Incandescent light bulbs are very
inefficient, converting less than 5% of the electricity used
into light, with the rest becoming heat.
LEDs are much more efficient than incandescent light
bulbs, and are increasingly being used for home lighting
and flashlights.
Project 5
Play a Melody
Build this circuit, then turn on the slide
switch (S1) to play a melody with the
melody IC (U32).
Project 6
Build the circuit shown, and place the fiber optic festive
tree in its mounting base and on the blink red LED (D11).
Turn on the slide switch (S1) and enjoy the show.
This circuit has four lights, 2 motors,
and music. Lights, sound, & motions!
