[請教]arduino seeed wifi shield
小弟我最近使用Seeed廠所出的 Arduino wifi shield V1.2，我使用他架設網站，每次都有Pin到但是卻哪部開網頁，請教各位大大是為什麼?

先單純使用以下程式碼測試 就知道是否跟SERVO碼有關?
=== Example 5: Controlling The Arduino Digital Pins From a Webpage (Toggling LEDs From an Webpage) ===
In this example we will create a webpage with three buttons to control three different digital pins in the Arduino.
For this tutorial follow the steps below. We have also created a video where we explain the code in more detail.
[https://www.youtube.com/watch?v=ek63patAl80 Video - WiFi Shield Arduino Digital Pin Control From Webpage]
'''Step 1: Hardware'''
Connect three LEDs and resistor to digital pins 11, 12, and 13 as shown in the schematic below:
[]
'''Step 2: Arduino Sketch'''
Upload the following code to your Arduino board but replace "mySSID" and "myPassword" with your access point's SSID name and password:
<syntaxhighlight lang="arduino">
#include <SoftwareSerial.h>
#include "WiFly.h"
#define SSID "KenMiao" // 輸入自己的 WiFi ID

// check your access point's security mode, mine was WPA20-PSK
// if yours is different you'll need to change the AUTH constant, see the file WiFly.h for avalable security codes
#define AUTH WIFLY_AUTH_WPA2_PSK
int flag = 0;
// Pins' connection
