Adding a button
Posted: Sat Aug 13, 2016 5:39 pmHello everybody,
I found a code in the web for turn on a led through a website using the ESP8266 webserver.
I want to add a button to my project.
This is the code:
When I should add the code to connect a button in the GPIO0 pin?
I hope you can help me.
Thanks
I found a code in the web for turn on a led through a website using the ESP8266 webserver.
I want to add a button to my project.
This is the code:
Code: Select all
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
MDNSResponder mdns;
// Replace with your network credentials
const char* ssid = "Thomson42FECF";
const char* password = "A8600DBD07";
ESP8266WebServer server(8000);
String webPage = "";
int gpio0_pin = 0;
int gpio2_pin = 2;
void setup(void){
webPage += "<h1>ESP8266 Web Server</h1><p>Socket #1 <a href=\"socket1On\"><button>ON</button></a> <a href=\"socket1Off\"><button>OFF</button></a></p>";
webPage += "<p>Socket #2 <a href=\"socket2On\"><button>ON</button></a> <a href=\"socket2Off\"><button>OFF</button></a></p>";
// preparing GPIOs
pinMode(gpio0_pin, OUTPUT);
digitalWrite(gpio0_pin, LOW);
pinMode(gpio2_pin, OUTPUT);
digitalWrite(gpio2_pin, LOW);
delay(1000);
Serial.begin(115200);
WiFi.begin(ssid, password);
Serial.println("");
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
if (mdns.begin("esp8266", WiFi.localIP())) {
Serial.println("MDNS responder started");
}
server.on("/", [](){
server.send(200, "text/html", webPage);
});
server.on("/socket1On", [](){
server.send(200, "text/html", webPage);
digitalWrite(gpio0_pin, HIGH);
delay(1000);
});
server.on("/socket1Off", [](){
server.send(200, "text/html", webPage);
digitalWrite(gpio0_pin, LOW);
delay(1000);
});
server.on("/socket2On", [](){
server.send(200, "text/html", webPage);
digitalWrite(gpio2_pin, HIGH);
delay(1000);
});
server.on("/socket2Off", [](){
server.send(200, "text/html", webPage);
digitalWrite(gpio2_pin, LOW);
delay(1000);
});
server.begin();
Serial.println("HTTP server started");
}
void loop(void){
server.handleClient();
}
When I should add the code to connect a button in the GPIO0 pin?
I hope you can help me.
Thanks
