首先解釋一下我的目標，我想控制我的機器人去前進，後退，左，右，用UDP （用戶數據報協議）協議Arduino的UDP平
- 我停止「M使用
- Arduino的贈送Atmega168的
- 蘭ENC28J60
- 路由器TP-LINK 150Mbps的無線N納米
- 電機驅動器L293D
，並在C＃中的按鈕前，後應用，左，右和停止
Arduino的IP地址爲192.168.178.60我查驗，如果我沒有問題地址，但嘗試點擊更快的按鈕來控制或點擊任何按鈕，並讓它更多的時間例如前進它阻止或離開它塊，我必須重新啓動arduino讓我ping回來。主要問題是爲什麼我失去了我的連接很快。
這裏是我的代碼
#include "EtherShield.h"
//8 or 16 bit integer
uint8_t mymac[6] = {0xCF,0x70,0x7C,0xE4,0x8A,0xB8};
uint8_t myip[4] = {192,168,178,60};
uint16_t MYWWWPORT = 80;
#define BUFFER_SIZE 750
static uint8_t buf[BUFFER_SIZE+1];
EtherShield es=EtherShield();
uint16_t dat_p;
