Control Arduino Through Serial Connection (USB) VB Visual Basic program LED exampleby 289359752424 views
I've uploaded a very similar looking demo to this! However, mine uses a 4 digit LCD screen and a AY0438 LCD driver, instead of all those transistors and resistors. Using a display driver you only need 4 outputs from the arduino to control 32 LCD segments. You can also drive seven segment LEDs like yours using my library and an M5451? chip - much easier to program. :)
My library is here code.google.com/p/arduino-seven-segment/
