Check weight decrease

[andrescvargasr]

There is a problem when the bioreactor start reduce weight (ex. 30%). The bioreactor doesn't check correctly the weight, it thinks the reduction is enough and continue with the next step while the weight is more than 30%.

Check HX711, we need to reduce the resistance R1/R2 in order to activate the PNP transistor.

Ex.: R1 20 k, R2: 13.3 k -> V_AVDD = 3.130 V < 3.2 V (100 mV less than VCC at least)
