Interfacing of Led With PIC:

Led ( Light emitting diode) :

Light Emitting Diodes are the mostly commonly used components in many applications. They are made of semiconducting material. This article describes about basic interfacing of LEDs to the 8051 family microcontrollers.

__CONFIG (WDTE_OFF&FOSC_HS&PWRTE_ON&LVP_OFF);

void delay(unsigned int i)

{

while(i--);

}

void main()

{

while(1)

{

TRISB=0x00;

PORTB=0xFF;

delay(5000);

PORTB=0x00;

delay(5000);

}

}
