Control an LED from Web browser, NODEMCU Esp8266

[@roidroid]

If you replace the line: *int ledPin = 13;* with *int ledPin = LED_BUILTIN;* Then you can just use the ESP8266's internal LED and don't need to add an extra LED. The on/off switching will be backwards, but you can fix that in the code if you want to.

Yep, thanks

Hi, Its awesome... I want to control 4 channel relay module... please make tutorial on this topic

[@syahirahaqilah4590]

Hi, I just want to know why there is nothing appear when I opened the serial monitor? The connecting sign also the ip address doesn't show. Can anyone help fix this?

[@hungrysquirrei6961]

Because your serial monitor doesnt show the history of communication - u should open the serial monitor at the same time u plug in ur esp. Or set ur delay to 5 seconds in this cycle, so u have plenty of time to open ur serial monitor and show the message at the time it is created: while (WiFi.status() != WL_CONNECTED) { delay(5000); Serial.print("."); }

Can you give me the library for Esp8266 please?

[@Jack_Mehoff_]

is it possible to change the size of the text and the buttons?

[@HarshalDoshiWellAhead]

yes, its possible Change below code as per your requirement. // Return the response client.println("HTTP/1.1 200 OK"); client.println("Content-Type: text/html"); client.println(""); // do not forget this one client.println(""); client.println(""); client.print("Led pin is now: "); if(value == HIGH) { client.print("On"); } else { client.print("Off"); } client.println(""); client.println("Turn Off "); client.println("");

[@technophileARG]

but my friend it's working if & only if the esp8266 and my browser is connected to the same wifi router!, how to control it from anywhere in the world?

[@ARG-gz7iz]

yes, same problem with me, please provide an appropriate solution if u know, thank you!

[@dekipet]

Beside that, anytime you disconnect it from pc it will need to be connected to it again, and start serial monitor to connect module to network. So, this is ok tutorial for beginners but it need a few modification for further use.

[@LionelTellem]

You got to use port forwarding on your router or use a VPN

[@RGPinger]

I have these projects and also control with voice. All from somewhere in world!

I have a problem with the "new client" I have changed the code a little bit to play music. I have these two "PacMan and Tetris" music. I can play the Pacman music all the time but after I played the Tetris music it just says "new client" and the side (when I press a new button) just reload nonstop. Can anyone please help me? Code: #include const char* ssid = "*******"; const char* password = "********"; int tonePin = 15; // GPIO15 WiFiServer server(80); void setup() { Serial.begin(115200); delay(10); // Connect to WiFi network Serial.println(); Serial.println(); Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected"); // Start the server server.begin(); Serial.println("Server started"); // Print the IP address Serial.print("Use this URL to connect: "); Serial.print(""); Serial.print(WiFi.localIP()); Serial.println("/"); } void loop() { // Check if a client has connected WiFiClient client = server.available(); if (!client) { return; } // Wait until the client sends some data Serial.println("new client"); while(!client.available()){ delay(500); Serial.print("."); } // Read the first line of the request String request = client.readStringUntil(' '); Serial.println(request); client.flush(); // Match the request if (request.indexOf("/Play=PacMan") != -1) { PacMan(); } if (request.indexOf("/Play=Tetris") != -1) { Tetris(); } // Set ledPin according to the request //digitalWrite(ledPin, value); // Return the response client.println("HTTP/1.1 200 OK"); client.println("Content-Type: text/html"); client.println(""); // do not forget this one client.println(""); client.println(""); client.println(" Tetris "); client.println(""); delay(1); Serial.println("Client disonnected"); Serial.println(WiFi.localIP()); Serial.println(""); } void Tetris() { a lot of music code (This is definitely not a problem) } void PacMan() { a lot of music code (This is definitely not a problem) } The Serial Monitor: WiFi connected Server started Use this URL to connect: 192.168.0.28/ new client .GET / HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=PacMan HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=PacMan HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=PacMan HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=PacMan HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=PacMan HTTP/1.1 Client disonnected 192.168.0.28 new client ...GET /favicon.ico HTTP/1.1 Client disonnected 192.168.0.28 new client .GET /Play=Tetris HTTP/1.1 Client disonnected 192.168.0.28 new client ............................
