A simple project to read a POT and control a couple LEDs using the very cool looking and cheap Arduino. Maybe the Arduino could be used to implement something like the DaysAgo Timer. Or maybe find one of the USB Interface chips to build something fun like the USB Hampster Wheel that responds to your [...]
LED Temperature Thermometer Project This LED temperature thermometer project will display the room temperature where it is placed using 10 LEDs, with each LED representing 2 degree Fahrenheit step, forming a bargraph display.
A group of us were interested in the Graffiti Research Lab’s Throwies and decided to try some for Fiesta in San Antonio. A throwie is an LED, small battery, and a strong rare earth magnet. The cost on all of these items is now low enough that you can make the throwies for under 50 [...]
Chris Lomont’s LED Cube Page Another cool project that I’d like to attempt someday. An alternative to controlling one of these with a pic or gumstick might be a few parallel ports on an old PC. The LED cube was a project started by Gene Foulk and I to create a large, animated, self contained [...]

Tutorial for LEDs and Transistors Nice tutorial about LEDs and Transistors. An LED is the device shown above. Besides red, they can also be yellow, green and blue. The letters LED stand for Light Emitting Diode. If you are unfamiliar with diodes, take a moment to review the components in the Basic Components Tutorial. The [...]
