: Make 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.To save you the time of creating the chart, the Open Office spreadsheet, ATMega168.ods is attached.

Print the Labels

I used a laser printer, but an ink jet should work just as well.Fold the labels for the legs of the chip before doing the final cut out. Those little labels for the pins are less that 1/8" wide and are hard to fold if the label has been cut to size before folding, but are easy if they are still connected.

Glue the Label on the Chip

In this photo, I pulled back the label "tent" so that you can see the chip under the label. To prevent the label tent from slipping I used a dab of rubber cement to hold the label in place. When you're done creating your prototype circuit, the label is easily peeled off the chip leaving no residue. The rubber cement doesn't melt the chip either.

The ATMega168 Label Is Complete

Prototype to your heart's content.
