    since you are using a switch so the onput will be either +5 v or 0 v

    so you can use two function to read the input

     

     

    bit_is_set(parameter1,parametre2)

     

     

    and

     

    bit_is_clear(parameter1,parameter2)

    U can make the port A pin as input as well as output…

    For example

               For reading as input.. put

     

               DDRA=0x00;
