I made this Arduino 8 bit binary led counter as a solution for one member from Arduino ... the schematic as usual and in the second one is how the schematic looks on the Fritzing breadboard layout.

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear.

I have been trying Fritzing, the free schematic capture and pcb layout tool ... To try it out, I designing a pcb for interfacing an Arduino to two robot motors (scroll down here for original design), ...
