    Code

    1. #include <avr/io.h>
    2. #define SW 0   
    3. #define LED 1
    4. int main(void)
    5. {     
    6.    DDRB &= ~(1<<SW);  //switch as input
    7.    DDRB |= (1<<LED); //led as output  
    8.    while(1)
    9.    {
    10. 	   if ((PINB&(1<<SW)) == 1)
    11. 	   PORTB |= (1<<LED);
    12. 	   PORTB &= ~ (1<<LED);
    13.    }
    14. }
