On my PC:
Get Arduino and TC4
Download and install Arduino IDE and Artisan program
Download TC4 aArtisan drivers and save them in Artisan scatch book location (My Document\Arduino\aArtisan)
Download TC4 libraries for thermcouples etc.. and save them to Artisan scatch book location (My Document\Arduino\libraries\...)
Open Arduino IDE, and choose File-Scatchbook-aArtisan, then Upload, and your setup is done.
Run Artisan, pick TC4 device, and you should see the temperatures when you click on ON button.
If your machine is not the newest one, choose to sample every 2-3 seconds to make machine more responsive.
I have the setup at this very computer and roasting with it every day and I will be happy to help.
