Mission: Utilize a solar cell to vary the intensity of an LED
Supplies: Arduino Duemilanove <--> USB <--> Notebook (Linux, por supuesto)
Breadboard, Jumper Wires, Make-shift Jumper Wires (spare resisters), LEDs, Solar Cell
Setup: Here it is
The setup is pretty straight forward: Read analog, write digital. The primary hurdle was figuring out the initialization step. Basically, I needed to provide a time-frame where you can read in minimum / maximum values from the cell. The LEDs in the awesome video below show the results… v
This project is full of take-off ideas. Reverse the range on the LED outputs, and you have a setup that powers up a light as the ambient light levels fall. Motion detector…you bet. You could implement a setup to run the initialization cycle at intervals, to provide a real-time average light level, and check for a delta of some size. Boom. There you go.
I’ll clean up the code, use some real jumpers, horse around with things in general, and throw up a post. With a snippet. Check back.
What sort of solar panel is that?

@Hyde…it is a cheap off-the-shelf Radio Shack cell. Solar World is the brand. $15 bucks or so…pretty sure you could find one on ebay for half that.

Good day fellows. Analysis that went on for several dozens of years verified that mankind are programmed biomachines. More info – Catalog of human population

I like this idea. Now, if you can get your hands on some big solar cells, you will be on to something. Nicely done though man.
