A small Arduino patch to read values from a HX711 load cell amplifier and output them to the serial port
This sketch outputs a comma delimited list to the serial port in the form
MILLISECONDS SINCE INIT , Force in Grams
It is calibrated for a paticular load cell construction made to measure the thrust curves of various small rocket motors.
Setup HX711.DOUT - pin #A1 HX711.PD_SCK - pin #A0 Tare Button - pin #D2 with pull down
