digital Pots under SPI control from an Arduino

[ronsherr1]

Is there any way that I could see the sketch you used for this demonstration?

Thanks in advance!

What are the Chip numbers,and why did you use them over any other?

@drewmaster74 these are MCP42XXX-I/P XXX=010, 050, 100 for the 10k, 50k, and 100k pots, respectively. I used these specific chips because they're cheap, relatively easy to use, available in a DIP package, and they have the number of pots that I needed (two each).
