Wii Balance Board Smart Scale ( w/ ESP32 )

I had never used load cells before so I didn't really know what needed to go into calibrating these things. 

What I did was turn the balance board upside down and placed a known weight on each load cell.  In my case I just had a small container of water that weighed 648 grams.

I took the raw value from each cell and came up with a calibration factor that would result in a value of 648 (or really close).

I then used those 4 calibration factors in the software for each load cell.  For now it seems ot be pretty close.  In the future I might get a little more scientific about it :)
