Whenever I wire my components as shown and run the following code nothing is printed in the serial monitor but as soon as I remove any wires connected to the data pin ( digital pin 4) the arduino will begin printing and eventually starts printing the weight as 0. Even if I connect the clock wire to the data pin the serial monitor will freeze.
float calibration_factor = -14; // this calibration factor is adjusted according to my load cell
float units;
float ounces;
void setup() {
Serial.begin(9600);
Serial.println("HX711 calibration sketch");
Serial.println("Remove all weight from scale");
Serial.println("After readings begin, place known weight on scale");
Serial.println("Press + or a to increase calibration factor");
Serial.println("Press - or z to decrease calibration factor");
scale.set_scale();
scale.tare(); //Reset the scale to 0
long zero_factor = scale.read_average(); //Get a baseline reading
Serial.print("Zero factor: "); //This can be used to remove the need to tare the scale. Useful in permanent scale projects.
Serial.println(zero_factor);
}
void loop() {
scale.set_scale(calibration_factor); //Adjust to this calibration factor
Serial.print("Reading: ");
units = scale.get_units(), 10;
if (units < 0)
{
units = 0.00;
}
ounces = units * 0.035274;
Serial.print(units);
Serial.print(" grams");
Serial.print(" calibration_factor: ");
