Hi everybody,
I just want to know why this code is not working, I want to turn on or off LED in a Timer by using HTTPClient...
#include <WiFi.h>
#include <HTTPClient.h>
#include <Timer.h>
const char* ssid = "Mehran";
const char* password = "************";
WiFiServer server(80);
Timer t;
void setup()
{
Serial.begin(115200);
pinMode(2, OUTPUT); // set the LED pin mode
pinMode(5, OUTPUT); // set the LED pin mode
pinMode(18, OUTPUT); // set the LED pin mode
delay(10);
// We start by connecting to a 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.");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
server.begin();
t.every(5000, TurnLED);
}
bool timer = true;
void TurnLED()
{
timer = false;
Serial.println("Timer Started");
HTTPClient http;
String serverPath = "http://192.168.1.100/H18";
http.begin(serverPath.c_str());
http.GET();
}
void loop(){
if(timer)
{
Serial.println("Update Timer");
t.update();
}
WiFiClient client = server.available(); // listen for incoming clients
if (client) { // if you get a client,
Serial.println("New Client."); // print a message out the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
Serial.println(c);
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println();
// the content of the HTTP response follows the header:
client.print("Click <a href=\"/H2\">here</a> to turn the LED on pin 2 Off.
");
client.print("Click <a href=\"/L2\">here</a> to turn the LED on pin 2 on.
");
client.print("Click <a href=\"/H18\">here</a> to turn the LED on pin 18 Off.
");
client.print("Click <a href=\"/L18\">here</a> to turn the LED on pin 18 on.
");
client.print("Click <a href=\"/H5\">here</a> to turn the LED on pin 5 Off.
");
client.print("Click <a href=\"/L5\">here</a> to turn the LED on pin 5 on.
");
// The HTTP response ends with another blank line:
client.println();
// break out of the while loop:
break;
} else { // if you got a newline, then clear currentLine:
currentLine = "";
}
} else if (c != '\r') { // if you got anything else but a carriage return character,
currentLine += c; // add it to the end of the currentLine
}
// Check to see if the client request was "GET /H" or "GET /L":
if (currentLine.endsWith("GET /H2")) {
digitalWrite(2, HIGH); // GET /H turns the LED on
Serial.println("--------------------------------------------------------");
Serial.println("H2");
timer = true;
}
if (currentLine.endsWith("GET /L2")) {
digitalWrite(2, LOW);
Serial.println("--------------------------------------------------------");
Serial.println("L2");
}
if (currentLine.endsWith("GET /H5")) {
digitalWrite(5, HIGH); // GET /H turns the LED on
Serial.println("--------------------------------------------------------");
Serial.println("H5");
}
if (currentLine.endsWith("GET /L5")) {
digitalWrite(5, LOW);
Serial.println("--------------------------------------------------------");
Serial.println("L5");
}
// GET /L turns the LED off
if (currentLine.endsWith("GET /H18")) {
digitalWrite(18, HIGH); // GET /L turns the LED off
Serial.println("--------------------------------------------------------");
Serial.println("H18");
}
if (currentLine.endsWith("GET /L18")) {
digitalWrite(18, LOW); // GET /L turns the LED off
Serial.println("--------------------------------------------------------");
Serial.println("L18");
}
}
}
// close the connection:
client.stop();
Serial.println("Client Disconnected.");
}
