So I using hx711 with a 200kg loadcell.
#include "HX711.h"
// HX711.DOUT - pin #A1
// HX711.PD_SCK - pin #A0
HX711 scale(A1, A0); // parameter "gain" is ommited; the default value 128 is used by the library
void setup() {
Serial.begin(38400);
Serial.println("HX711 Demo");
Serial.println("Before setting up the scale:");
Serial.print("read: tt");
Serial.println(scale.read()); // print a raw reading from the ADC
Serial.print("read average: tt");
Serial.println(scale.read_average(20)); // print the average of 20 readings from the ADC
Serial.print("get value: tt");
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: tt");
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)
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: tt");
Serial.println(scale.read()); // print a raw reading from the ADC
Serial.print("read average: tt");
Serial.println(scale.read_average(20)); // print the average of 20 readings from the ADC
Serial.print("get value: tt");
Serial.println(scale.get_value(5)); // print the average of 5 readings from the ADC minus the tare weight, set with tare()
Serial.print("get units: tt");
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:");
}
void loop() {
Serial.print("one reading:t");
Serial.print(scale.get_units(), 1);
Serial.print("t| average:t");
Serial.println(scale.get_units(10), 1);
scale.power_down(); // put the ADC in sleep mode
delay(5000);
scale.power_up();
}
But I don't get any readings, I tried changing the uno,loadcell and hx711 ,still no readings. What should I do? need help please
