I am currently trying to connect my WiShield v1.0 to my wifi router. I am able to get it connected and display the information when I go to its IP address, I also have a LM335 Temperature monitor that is able to print all of the temperatures in Serial but I just don't know how to get it to print it on the webpage. Here is the code, can someone please help me get this to print on the webpage.

Hello ,

The code for the url is not in the loop on the WiShield, i will post mine ( i am using the DHT11 sensor for the temp. and hum.) if you want convert the part for you're sensor.

Here you are:

#include "DHT.h"

#define DHTPIN 5 // what pin we're connected to

// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302)
//#define DHTTYPE DHT21 // DHT 21 (AM2301)


DHT dht(DHTPIN, DHTTYPE);


#include <WiServer.h>

#define WIRELESS_MODE_INFRA	1
#define WIRELESS_MODE_ADHOC	2

// Wireless configuration parameters ----------------------------------------
unsigned char local_ip[] = {192,168,2,22};	// IP address of WiShield
unsigned char gateway_ip[] = {192,168,2,1};	// router or gateway IP address
unsigned char subnet_mask[] = {255,255,255,0};	// subnet mask for the local network
const prog_char ssid[] PROGMEM = {"NetFasteR_rXfAD4"};		// max 32 bytes

unsigned char security_type = 3;	// 0 - open; 1 - WEP; 2 - WPA; 3 - WPA2

Don't forgot also to change the ip in case if it is different, and the WEP key (or what you have) to you

Here is mine

unsigned char security_type = 3; // 0 - open; 1 - WEP; 2 - WPA; 3 - WPA2

// WPA/WPA2 passphrase
const prog_char security_passphrase[] PROGMEM = {"password"}; // max 64 characters
