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 ...

[PatH] from WhiskeyTangoHotel choose the latter route, and built a super simple LED controller for his KLR650 bike. He chose a commonly available 18 W light bar module containing six 3 W LEDs.

Our only wish is that subsequent yellow-light button presses would make it speed up even more. ... and I was inspired to build a project based on your 1D LED pong, Arduino-style project.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

With each contact you make, the red LED lights up, the buzzer beeps and the seven-segment LED display counts up. After making contact ten times, the buzzer blares out an annoying sound — game over.

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The entire system is built on the backbone of an Arduino Uno with a few other parts totaling at about $150. That seems expensive, but DeBoisblanc's build covers a lot of ground.

This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the color and intensity of the ambient lights on the back of the display to match ...
