可以自己改的程序，控制电器的开关，DIY弄个控制器。
#define uint unsigned int
#define uchar unsigned char
sbit led = P3^4;
sbit out =P3^5;
uchar aa;
uint time;
void init()
{
TMOD=0x01;
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
EA=1;
ET0=1;
TR0=1;
aa=0;
time=0;
out=0;
}
void main()
{
init();
while(1);
}
void timer0() interrupt 1
{
TH0=(65536-50000)/256; //?50MS??????,??????????aa
TL0=(65536-50000)%256;
aa++;
if(aa>=6.5) //????0.5S
{
led=~led;
aa=0; //??aa
time++;
if(time>=120)//2*8*60*60=57600
{
out=1;led=1;TR0=0;
}
}
}
