Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller. (Click the links to see PDFs of the complete ...

Both use electricity and both give off light, but that's where the similarity ends. The solution is to buy a dimmer switch rated for both CFL and LED bulbs.

This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it’s not limited to blinky lights alone. … ...

Light-emitting diodes, or LEDs, all the way. Halogen light bulbs are the most like incandescent but they don’t last as long and aren’t as energy efficient as CFLs and LEDs.
