when the weight is under 200 gram, then the servo motor will triggered. Below is my code, the code can be compile but there is no show error

#include "HX711.h"
#include <Q2HX711.h>
#include <Servo.h>




Servo myservo;

const byte hx711_data_pin = D5;
const byte hx711_clock_pin = D6;
int servoPin= 8;

float weight= 500;

HX711 scale;


Q2HX711 hx711(hx711_data_pin, hx711_clock_pin);

void setup() {
Serial.begin(9600);
scale.begin(hx711_data_pin, hx711_clock_pin);
scale.set_scale(96.3);
scale.tare(50);
myservo.attach(8,600,2300);

}

void loop() {
// float h = hx711.read()/100.0;
float weight = scale.get_units(25);
Serial.println(weight);

if (weight < 200) {

myservo.write(90);
delay(1000);

}

}
