Step 5: Faux Circuit making Time!

Here is the fun part... well in my opinion the whole thing is fun but whatever...
Now that you have your printed out templates you can start making your circuit. Now is the time to glue down your foil where ever your rows and columns are supposed to go. Look at figure 2 for both of my circuits, yours should look somewhat like this. Also, notice how my leads go away from the keypad in an organized way to facilitate easy hook-up? Just like I planned!

*NOTE* At this point its a good idea to re-make your front design to include labels for the hookup at the end of the leads with the labels
R1
R2
R3
C3
C2
C1

This is just going to make it easier for you.
