the servos and buzzer do not reply
The idea is that I have an application that has a button that when pressed sends 1 and in this case the default servo angle changes from zero to 90 and the bells work for two seconds and when pressed again sends 2 and in this case the servo returns to the default state of 0 The Bluetooth is connected to the application well and the tr and rx flash in the Arduino when I press the button which means that the Arduino receives the message but here is the problem nothing works from the bells or the servo whyyyy And these are the application codes and the Arduino code:
#include <Arduino.h>
#include <Servo.h>
// تعريف المنافذ
const int buzzer1 = 2;
const int buzzer2 = 3;
const int servo1 = 4;
const int servo2 = 5;
const int servo3 = 6;
const int servo4 = 7;
char data; // متغير لتخزين البيانات المستلمة
Servo myServo1;
Servo myServo2;
Servo myServo3;
Servo myServo4;
void setup() {
Serial.begin(9600); // فتح الاتصال التسلسلي
pinMode(buzzer1, OUTPUT);
pinMode(buzzer2, OUTPUT);
myServo1.attach(servo1);
myServo2.attach(servo2);
myServo3.attach(servo3);
myServo4.attach(servo4);
// تحديد الوضع الافتراضي للسيرفو عند البدء
myServo1.write(0);
myServo2.write(0);
myServo3.write(0);
myServo4.write(0);
}
void loop() {
if (Serial.available()) {
data = Serial.read(); // قراءة البيانات المستلمة
Serial.print("Received: ");
Serial.print(data);
if(data==1){
// إعادة المحركات للوضع الابتدائي
Serial.println("Command 1: Resetting servos");
myServo1.write(0);
myServo2.write(0);
myServo3.write(0);
myServo4.write(0);
}
if(data==2){ // تشغيل الجرس وتحريك المحركات
Serial.println("Command 2: Activating servos and buzzers");
// تشغيل البازارات لمدة 1 ثانية
tone(buzzer1, 1000);
tone(buzzer2, 1000);
delay(1000);
noTone(buzzer1);
noTone(buzzer2);
// تحريك السيرفو
myServo1.write(180);
myServo2.write(180);
myServo3.write(180);
myServo4.write(180);
}
}
}
