LED Photo Project
the circuit that I put together with LEDs that actually turned out
much better than I planned. I needed some pictures for the website
and so I decided to try my hand at taking my own.
breadboarded several different colored LEDs with some current
limiting resistors and lit them up. Here is the simple schematic.
* The circuit draws about 140ma @
* Resistors are 1/2 Watt.
* The LED's were just some I
had lying around. I adjusted the load resistor values to give the
most uniform brightness among the LED's.
* The power supply was
just an adjustable wall transformer I purchased from Radio Shack.
Then I turned out the lights and
looped a piece of paper around and up the back and over the topof
With my camera on a tripod, I just turned off the flash and started
snapping pictures while moving the paper around to make different
This is what I came up with. Pretty cool, huh?
I came up with lots of designs and lots of pictures.
(The wonderful thing about digital
cameras, if you don't like the picture, you delete it.)
Notice the header at the top of the
webpage is from this session of pictures. I just stretched, cropped,
and played with the colors, (Using Windows Picture Manager) and came
up with the header.
