Stap 4: Library voor Arduino
<p>//The library used for arduino https://github.com/bogde/HX711<br>// LCD can also be used instead of serial #include "HX711.h" // HX711.DOUT - pin 10 // HX711.PD_SCK - pin 11 HX711 scale(10, 11); // parameter "gain" is ommited; the default value 128 is used by the library library*/</p><p>void setup() { Serial.begin(38400); Serial.println("HX711 Demo");</p><p> Serial.println("Before setting up the scale:"); Serial.print("read: \t\t "); Serial.println(scale.read()); // print a raw reading from the ADC Serial.print("read average:\t\t "); Serial.println(scale.read_average(20)); // print the average of 20 readings from the ADC Serial.print("get value: \t\t "); Serial.println(scale.get_value(5)); // print the average of 5 readings from the ADC minus the tare weight (not set yet) Serial.print("get units: \t\t "); Serial.println(scale.get_units(5), 1); // print the average of 5 readings from the ADC minus tare weight (not set) divided by the SCALE parameter (not set yet) </p><p> scale.set_scale(2280.f); // this value is obtained by calibrating the scale with known weights; see the README for details scale.tare(); // reset the scale to 0 Serial.println("After setting up the scale:"); Serial.print("read: \t\t"); Serial.println(scale.read()); // print a raw reading from the ADC Serial.print("read average:\t\t "); Serial.println(scale.read_average(20)); // print the average of 20 readings from the ADC Serial.print("get value: \t\t "); // print the average of 5 readings from the ADC minus the tare weight, set with tare() Serial.println(scale.get_value(5));</p><p>Serial.print("get units: "); Serial.println(scale.get_units(5), 1); // print the average of 5 readings from the ADC minus tare weight, divided by the SCALE parameter set with set_scale Serial.println("Readings:"); }</p><p>void loop() { Serial.print("Weight :"); /* ---------Weight in terms of KG-------------*/ Serial.print(scale.get_units()*0.1 , 1); Serial.print("KG");</p><p> scale.power_down(); // put the ADC in sleep mode delay(5000); scale.power_up(); }</p>
