This is a fun project that
allows you to build a small blinking Christmas tree out of a
Pine Cone and a few electronic parts. Besides having fun,
you will learn about LED's, resistors and soldering. Not to
mention allowing your imagination to run wild. The Pine
Cone forms the body of the tree and we mount a bright white
steady LED at the top. The other LED's are blinking types that
randomly change between red, green and blue. They are also
bright LED's but we cut down a little on the brightness for
better affect and also to allow the 9 volt battery to last
longer.
Your kit should look a lot like this:
The kit contains:
- 12
multi-color LEDs
- 1 white LED
(Marked white tape on the leads).
- 13 470
ohm resistors
- 1 - 9 volt
battery connector
- 12 feet
of yellow wire
- 13 feet of
black wire
- 1 foot of red
wire
- Extra blue wire
to practice stripping (Wire is 30 gage)
- 1 clothes pin
- 1 mounting
paper plate
- 1 piece of heat
shrink tubing (Black, White or Green)
You need to supply:
9 volt
battery, small soldering iron, solder and small tools.
