I want to run D3 and D4 LED's in loop continuously

Subhendu Mondal

I have two button "Pattern1" and "Pattern2" , I want to run 2 LED pattern by using esp8266 and web browser,  If I click on "Pattern1" button the first pattern of both LED’s should run in loop continuously, and when I click "Pattern2" button the second pattern should run in loop continuously until I click any other button.

My Code is:

#include <ESP8266WiFi.h>

const char* ssid = "MY_SSID";
const char* password = "MY_SSID_PASSWORD";

WiFiServer server(80);

#define LED1 D3
#define LED2 D4

void setup() {
  pinMode(LED1, OUTPUT);
  pinMode(LED2, OUTPUT);
 
  digitalWrite(LED1, LOW);
  digitalWrite(LED2, LOW);
 
  Serial.begin(115200);
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("NodeMCU is connected to WiFi");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
  server.begin();
  delay(3000);
}

void loop() {
  WiFiClient client;
  client = server.available();

 if (client == 1) {
    String request = client.readStringUntil('\n');
    client.flush();
    Serial.println(request);
    
    if (request.indexOf("pattern01") != -1)
    { pattern1();}           // This Pattern I want to run continuously until I click any other button on web page
 
    if (request.indexOf("pattern02") != -1)
    { pattern2();}           // This Pattern I want to run continuously until I click any other button on web page

 
    client.println("HTTP/1.1 200 OK");
    client.println("Content-Type: text/html");
    client.println("");
 
    client.println("<!DOCTYPE HTML>");
    client.println("<html>");
    client.println("<head>");
    client.println("<title> Led Pattern </title>");
    client.println("</head>");
    client.println("<body align= \"center\" >");
    client.println("<h3> <font size = \"20\" face = \"Verdana\" >  Led Pattern Continue Loop Control  </font> </h3> ");
    client.println("<p> <a href=\"/pattern01\"> <button style=\"height:60px; background-color: #195B6A; width:200px; cursor: pointer\"><b> Pattern 1 </b></button> <a> </font></p> ");
    client.println("<p> <a href=\"/pattern02\"> <button style=\"height:60px; background-color: #195B6A; width:200px; cursor: pointer\"><b> Pattern 2 </b></button> <a> </font></p> ");
    client.println("</body>");
    client.println("</html>");

    Serial.println("Client disonnected");
    Serial.println("------------------");
    Serial.println("                  ");
       
  }
}

    It uses LDR to sense light intensity and LEDs to vary light intensity. signal becomes zero and actuator generates desire output continuously. D5, D6 and D7 of LCD are connected to digital pins D5, D4, D3 and D2 respectively. Initially when circuit is switched ON, it will start calibrating LDR as per light this.
