Question

请使用Nodemcu上的两个或多个led控件的代码来帮助您，我有一个LED控件的代码，并且无法使其在两个或多个上工作。我在Martyn Currey网站上找到了这个惊人的代码，并写了给他，但没有得到答案，所以我请您帮忙。我有一个很棒的代码，可让我控制一个来自nodemcu上的网络的LED，我想控制两个分离的LED，请您帮忙。这是代码：

#include <ESP8266WiFi.h>
const char WiFiPassword[] = "wifi";
const char AP_NameChar[] = "wifi" ;
WiFiServer server(80);
String header = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n";
String html_1 = "<!DOCTYPE html><html><head><meta name='viewport' content='width=device-width, initial-scale=1.0'/><meta charset='utf-8'><style>body {font-size:140%;} #main {display: table; margin: auto;  padding: 0 10px 0 10px; } h2,{text-align:center; } .button { padding:10px 10px 10px 10px; width:100%;  background-color: #4CAF50; font-size: 120%;}</style><title>LED Control</title></head><body><div id='main'><h2>LED Control</h2>";
String html_2 = "";
String html_4 = "</div></body></html>";

String request = "";
int LED_Pin = D7;
int LED_Pin2 = D8;

void setup() 
{
    pinMode(LED_Pin, OUTPUT); 
    pinMode(LED_Pin2, OUTPUT); 

    boolean conn = WiFi.softAP(AP_NameChar, WiFiPassword);
    server.begin();

} // void setup()

void loop() 
{

    // Check if a client has connected
    WiFiClient client = server.available();
    if (!client)  {  return;  }

    // Read the first line of the request
    request = client.readStringUntil('\r');

    if       ( request.indexOf("LEDON") > 0 )  { digitalWrite(LED_Pin, HIGH);  }
    else if  ( request.indexOf("LEDOFF") > 0 ) { digitalWrite(LED_Pin, LOW);   }

    // Get the LED pin status and create the LED status message
    if (digitalRead(LED_Pin) == HIGH) 
    {
        // the LED is on so the button needs to say turn it off
       html_2 = "<form id='F1' action='LEDOFF'><input class='button' type='submit' value='Turn of the LED' ></form><br>";
    }
    else                              
    {
        // the LED is off so the button needs to say turn it on
    html_2 = "<form id='F1' action='LEDON'><input class='button' type='submit' value='Turn on the LED' ></form><br>";
    }

    client.flush();

    client.print( header );
    client.print( html_1 );    
    client.print( html_2 );
    client.print( html_4);

    delay(5);
  // The client will actually be disconnected when the function returns and 'client' object is detroyed

} // void loop()

请帮助。
