Arduino Code for Water Dispenser Control

This Arduino code reads the water level sensor and controls a pump based on the sensor state. It also sends the sensor and pump states to a server.

// Libraries included
#include <WiFi.h>
#include <HTTPClient.h>

// Global Variables
String serverName = "https://7b1bd7318-bc4d-4740-a62d-d7195741dcee-00-2biv5sob6tgpp.spock.replit.dev/bebedero.php";
int sensorLevel = 34; // Pin where the level sensor is connected
int pumpPin = 5; // Pin where the pump is connected

void setup() {
    Serial.begin(115200);
    pinMode(sensorLevel, INPUT);
    pinMode(pumpPin, OUTPUT);

    }
    Serial.println("WiFi connected.");
}

void loop() {
    if (WiFi.status() == WL_CONNECTED) {
        HTTPClient http;
        http.begin(serverName);

        int sensorState = digitalRead(sensorLevel);
        int pumpState = (sensorState == HIGH) ? HIGH : LOW;
        digitalWrite(pumpPin, pumpState);

        String httpRequestData = "sensor=" + String(sensorState) + "&pump=" + String(pumpState);
        int httpResponseCode = http.POST(httpRequestData);
