As promised, here comes the code, along with the Fritzing file as a schematic view of the whole thing.

Hit the jump for the downloads. No wall of text his time.

Ready to get to the real stuff? In comes the schematics!

All these have been done with Fritzing, a circuit design tool for Arduino users and beginners in general.
While it is still in alpha phase and therefore has quite a few annoying bugs, it is definitely usable and easy to use.

Anyway, here is the breadboard view of the design:

As promised here, the first content post on tinyLogic! Yay \o/

After some basic tests of my recently acquired Arduino Duemilanove and assorted components, I was ready to implement something more complex, and learn more of the basics along the way. I got a lot of interesting (and cheap) components from a german surplus online store, so I decided to incorporate the following components into the build:

• linear slide potentiometer (some user interface that is not an on/off button)
  
• RGB LED (blinking is fascinating, colorful blinking is even more so!)
• 7-segment LED display(s) (I wanted some meaningful output)
  
• transistors (digital switches, also fascinating)
  
• Arduino (something to control, and therefore power!)
