Control Led through Wi-Fi

Control Led through Wi-Fi

In this project,we will use a Zduino WiFi to make a wireless control LED, control it turn brighter or darker on mobile phone or other wireless device in the same Wi-Fi through UDP or TCP protocol.

Preparation:

We need a Zduino WiFi, a relay module, a led, a Led,and many dupont lines. Connect them like this:

Install a Network debug assistant on your PC or some devices else.

About the Code:

#define SSID       "xxxxxxxx”// A wifi you want to join in.
#define PASSWORD   "xxxxxxxx”//the password of this wifi.

#include "OpenWIFI.h"
#include <SoftwareSerial.h>

WIFI wifi;

void setup()
  {
              delay(3000);
              wifi.begin();
              DebugSerial.println(wifi.GMR()); 
              delay(2000);
                 bool b = wifi.Initialize(AP_STA, SSID, PASSWORD);
                  if(!b)
                      {
                       DebugSerial.println("Init error");
                      }
             DebugSerial.println(wifi.showMode()); //back cwmode  
              delay(8000);
                 DebugSerial.println(wifi.showJAP()); //receive ssid of current connection
              DebugSerial.println("show the ip address of module");
                  DebugSerial.println(wifi.showIP());//show the ip address of module
              delay(8000);
             wifi.ipConfig(UDP,"192.168.1.14",8080,1,1113,0,4);
             DebugSerial.println("setup done..");
              pinMode(13,OUTPUT);
 }
void loop()
{
      char buf[100];
      int iLen = wifi.ReceiveMessage(buf);
       if(iLen > 0)
            {
              if (strcmp(buf, "HIGH") == 0)
                      {
                          digitalWrite(12, HIGH);
                      }
                else if (strcmp(buf, "LOW") == 0)
                      {
                        digitalWrite(12, LOW);
                      }
            }
}

Upload this Code to Zduino Wi-Fi,then open Network debug assistant,set the Network debug assistant like this

Picture

Then control the Led through send “HIGH”or”LOW”.Of course you can D.I.Y. It through edit the Code.
