ESP32 and servo WiFi

Projects General Guidance
1

Hello, I'm working with an ESP32 to create a scale model, but have truble making a Servo work.
With a siple code the servo works properly (like tutorialas on "how to use a servo" "move fron 0 to 170"), but I need it to be part of a bigger one which controls other elements.

With the ESP32 I create a web server with sliders and this one in particular works fine (it sends the correct data) activates a led but doesn't controls the servo position.

The slider is the "time of the day" and it is recived fine. Later that hour is converted by map funcion to the position of the servo, thats where the problem is cause the position is writen but not moves the servo. Truble in the "Solar" section.

I check that my power sourse works (5V 20A), which the led is also being powered.

The code is just what I think is not working

#include <WiFi.h> 
#include <ESP32Servo.h>

const char* ssid = "INVITADOS";
const char* password = "invitados00--";

const int Sled1 = 17;
Servo myServo;
const int servoPin = 16;

WiFiServer server(80);

String sliderValue2 = "0";

If so, add serial.print to every servo.write for debugging

I have already done that, I check that the possition is correct.

4

And you tested your setup with library example code?

5

Yes I did I used the same libraries. This is the code I used for the example:

#include <ESP32Servo.h>

Servo myServo;  // Crea un objeto Servo

const int servoPin = 18;  // Pin del ESP32 conectado al servo

void setup() {
  Serial.begin(115200);  // Inicia la comunicación serial
  myServo.attach(servoPin);  // Asigna el pin al servo
}

void loop() {
  // Mueve el servo de 0° a 180° y de vuelta
  for (int pos = 0; pos <= 180; pos += 5) {
    myServo.write(pos);  // Mueve el servo a la posición 'pos'
    Serial.print("Posición del servo: ");
    Serial.println(pos);  // Muestra la posición en el monitor serial
    delay(20);  // Pequeña pausa para que el servo se mueva
  }

  for (int pos = 180; pos >= 0; pos -= 5) {
    myServo.write(pos);
    Serial.print("Posición del servo: ");
    Serial.println(pos);
    delay(20);
  }
}

Serial.print here?

So, what is the output of the map function?
