Ah- fantastic! So I will just make volume an unsigned long as well, and all should be solved! I'll try that right away!
As for the video- I certainly will! Here is a still picture or two in the meantime:
(NOTE: this enclosure is ONLY for use while I build the full bar downstairs- none of it (except the faucet and skull) will be in the looks of the finished product. I just spiffed it up with the paint so it wouldn't be such an eyesore while it sits upstairs in my kitchen. Plus, I have a party every week on tuesday- and it makes people laugh to see R2-D2 with moonshine Xs on him
Here is what the effect lighting looks like while idle (I used RGB LEDs, so I can toggle this "default" color if I like)
And here is what the lights change to when pouring, to include the skull lighting. Now, in the FINISHED BarBot, every LED you see here will be behind a skull, and the 7th skull (the one in this photo) will not be filled with liquid. It will be positioned above the faucet sort of like it is now, and it will have the arduino and PCB inside of it- with all the wires coming down like a spinal cord.
Here is the arduino setup now- but once I have it exactly how I want it I will use Eagle to design and etch my own custom PCB for it, making it much smaller and more manageable (etching the PCB sounds fun!)
Last but not least- here is a mockup of the wheel that will hold your glass. The lazy susan bearing I need is still in the mail- so this is just a prototype that isn't motorized (PLUS- I NEED to find a reasonably accurate servo motor that turns at LEAST 180 degrees, with enough torque to turn the wheel plus a glass of liquid... I haven't had time to really search for one yet- if you know of one, PLEASE let me know!)
The coolest part of the wheel is the five slots for shot glasses. When finished- the Barbot will count the number of glasses in the slots whenever a shot recipe is selected, and pour-rotate-pour-rotate until all inserted shot glasses are filled- thus being able to pour 1-5 shots at a time based on how many glasses you put in the wheel! I am excited about that feature.
Hope you like the photos!
