Hello Sara , I want to connect an external button switch. In addition to the web server smart switch, I can also use an external button to turn on/off the LED. But I don’t know how to achieve it. I have tried it but all failed. Please help me thanks.

A Part of the code I modified is as follows:

const int buttonPin = 12;
int val;
pinMode(buttonPin, INPUT);

void loop()
{
……..

val=digitalRead(buttonPin);

if(val==HIGH)


        {

           delay(2000);

           Serial.println("GPIO 14 ON");

           client.println("
");

           digitalWrite(G_LED, HIGH);

        }
        else
        {

           delay(2000);

           Serial.println("GPIO 14 OFF");

           client.println("
");

           digitalWrite(G_LED, LOW);

}

…….
}

hello, I want to connect an external button. When the button is pressed, ESP8266 WEB server ON changes to OFF. I tried to modify this part of the program code as follows:
But I still can’t use buttons to control the status of the webpage. Please help me how can I modify it. Thanks.

const int R_BTN=14;

void setup()
{
pinMode(R_BTN,INPUT_PULLUP);
.
.
}
.
.
.

val=digitalRead(R_BTN);

if (header.indexOf(“GET /5/on”) >= 0)
{
Serial.println(“GPIO 5 on”);
output5State = “on”;
digitalWrite(output5, HIGH);
}

if(val==LOW)
{
delay(200); //Delay button
output5State = “off”;
digitalWrite(output5, LOW);

}

/*
else if (header.indexOf(“GET /5/off”) >= 0)
{
Serial.println(“GPIO 5 off”);
output5State = “off”;
digitalWrite(output5, LOW);
}
*/

Hi.
Yes, it should be possible, but at the moment we don’t have that exact project.

Hello. I tried the code in this page with my esp8266, and it works well.
Then I tried also the code for telegram notification, and it works also well.
Is it possible to merge them, so to have a (simple) web server, that in some case sends a telegram notification?
If not, is there a way to have this web server + another notification service?

Thanks
Sergio

Hello. I tried your codes for ESP8266 web server and for ESP8266 telegram, and both work, very good.
Is it possible to mix them? So to have a web server and if needed send a telegram notification?
I tried, but I cannot do this.
If not, is there a way to open a web server and send a notification in the same project, with another service?

Thank you very much
Sergio

Hallo Sara
I have done it time bevor and onesmore now. –> Same result.
For test I have reduced the Baudrate to 9600 Baud –> then the printout is ok.

Is it a driver or a USB problem?

Hi.
After uploading the code to the board, open the Serial monitor. Then, reset the board by pressing the RST button so that it starts running the code from the start.
When you open the Serial monitor, the board is probably already running the code, so you can’t see the first print statements.

Sara
