How to Weigh Multiple Items With a Microcontroller

  Serial.printf("\n\nTaring Scale\n");
  scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN, 32);    // Set gain to 32, uses B- and B+ on the HX711 Board
  //scale.set_gain(32);
  scale.tare(10);                      // Set ZERO using an averaged 10 readings
  scale.set_scale(LOADCELL_DIVIDER);   // Reads out in grams, approximately (for my test setup)
}

// CALCULATING SCALE:  ( scale.read() - scale.offset ) / KnownWeight
// Example:              ( 34811 - (-7209) ) / 203g = (  34811 + 7209  )  / 203g =  206
// scale.set_scale(206);
