Okay, finally got time to get it done so here we go.
First 2 images are how I prepared the potentiometer. I used a 10Kohm potentiometer, since it would add a much smaller load to the Arduino than the 5K, and one of the 10 ohm resistors in the kit.
Then I soldered the other 10 ohm resistor on the bottom of the board to allow room for the pot on top.
Then I soldered in the pot and resistor combo. front leg of pot goes in front hole and resistor leg goes in second hole.
third leg with green wire goes to ground pin. Then I used some hotglue to secure the back end of the pot.
this provided a nice low profile and didn't interfere with the stacking of the shields.
You will also notice that I soldered both legs of R16 to the board but removed pin 53.
I then soldered a wire from the leg of R16 to the leg of R32 that directly connects to pin 4
so far so good, board has tested good, though I had to use a IC2 scanner to get my RTC working correctly.
