This Instructable is really simple. I was inspired by tymm's uDuino bare bones interface for breadboarding an Arduino, but thought that one thing was missing. The Arduino pin descriptions, D0, D1, A0, A2, etc., don't match up directly with the ATMega168 or ATMega328's twenty-eight pins. The information for mapping the pins is easily available on the Arduino web site but I wanted something even simpler. My Instructable is a simple paper label that makes the translation of the pins simple.

Signing UpStep 1Make a spreadsheet
The first step was to create a spreadsheet. I used Open Office since it's available for Windows, Mac, and Linux and it's free for the downloading. Using Open Office, I created the spreadsheet ATMega168.ods.
The cells have to be really small. The rows are 0.1 inch high to match the 0.1 inch spacing of the ATMega 168 pins. By trial and error, I found that the smallest font I could use was 6 point Arial Narrow, and the column widths are 0.12 inches for the pin numbers (columns A, D; F, I; and K, N), and the pin labels can be 0.18 inches wide (columns B,C; G,H; and L,M). Once I made one chart, I just duplicated the chart several times so I didn't have to use one sheet of paper to print out one tiny label.
The asterisks by some of the pin labels, D3, D6, etc., indicate that these pins support pulse width modulation, PWM.
UPDATE: Users have reported trouble saving the Open Office .ods file. It gets saved as a file with a .tmp file extention. Instead, right click on the file and select Save File As, and enter the name you desire with a .ods file extension.
To save you the time of creating the chart, the Open Office spreadsheet, ATMega168.ods is attached.

Am I doing something wrong?

Had to drop the font size for the pin numbers to 5pt to fit into the 012" cell size.
The font in your pdf looks different which is maybe why it fits better.

I found a similar, designed as a label to stick on top of the chip at Tod E. Kurt's site. He left out pin numbering, as I would too, but your spreadsheet approach is much easier to do from scratch or modify to personal needs.
My installation of OOo 3.0 on Ubuntu 9.04 AMD64 did not have the font you use, I had to change to Times New Roman 4.5 points in order to fit, but it is very hard to read after printing.
