I am guessing here that you are referring to the Parola modules and not Mel's clock project 
Not sure what you mean by the control module, and I can't see a reference to it on the Tayda site. The instructions are basically the same as the BoM PDF file on Google code site (link below).
The controller in the video is an Arduino Uno running one of the example sketches that come with the Parola library download. The switches and pots are just connected to a I/O shield, I just have pre-built switches, etc, on small PCBs with standard Ground Volt and Signal (GVS) headers that make hooking up things easier and faster. The details of the pins connected are in the sketches.
If you meant something else, please let me know. If you are interested in the modular approach to my system, I am happy to share as it is not my original idea.
