Code

Untitled file

C/C++
Should work with any dev board, its really simple
#include<reg51.h>

sbit led=P0^0;

void delay(unsigned int a)
{			 

int i, j;
	for(j=0;j<a;j++)
		for(i=0;i<100;i++);
		
}

void main()
{

//The 8051 dosent have what it takes to drive the LED
//hence the circuit
led=0;//off
delay(1000);
led=1;//on
delay(1000);

	
}
