However, I get this error when I try to go to the URL:
This site can’t be reached
I have tried connecting to the ESP in my wifi networks, but nothing connects. Any help would be appreciated.
Here is my code:
#include <ESP8266WiFi.h>
const char* ssid = "Bridgette's Thunderdome 2.4";
const char* password = "Password";
int ledPin = 13; //gpio13 mapped for d7
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
pinMode(ledPin,OUTPUT);//
digitalWrite(ledPin, LOW); //default pin off
//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("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
int sensorReading = analogRead(17);
//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(1);
}
//Read the first line of the request
String request = client.readStringUntil('r');
Serial.println(request);
client.flush();
//Match the request
int value = LOW;
if (request.indexOf("/LED=ON") != -1) {
digitalWrite(ledPin, HIGH);
value = HIGH;
}
if (request.indexOf("/LED=OFF") != -1) {
digitalWrite(ledPin, LOW);
value = LOW;
}
//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("");
client.println("<!DOTYPE HTML>");
client.println("<html>");
client.print("analog input ");
client.print(" is ");
client.print(sensorReading);
client.println("<br />");
client.println("<br><br>");
client.println("<a href=\"/LED=ON\"\"><BUTTON>Turn On <\button></a>");
client.println("<a href=\"/LED=OFF\"\"><button>Turn Off </button></a><br/>");
client.println("</html>");
delay(1);
Serial.println("Client disconnected");
Serial.println("");
