## This is up until 07 First Run - Reading Data from the Load Cell with Python on Raspberry Pi

## Next Steps
# We have to calibrate the load cell to get an actual weight value
# Since we are using 3 load cells, the max percent full for each would be 33% of the 
# total, therefore if the max fill = 40 lbs (as estimated) then percent fill for each load
# cell would be % = (reading / (1/3 max fill)) * 100
