0 or 1 to the port pins its connected to, i just want to know how i will connect it.

Thanks.

like this :eek:ne end connect to he mcu with a 10k resistance pll high,and the other end connect to ground?so easy?
 

interfacing switch to microcontroller

PORTB has built in weak pullups, you have to enable them RBPU
Connect one side of your DIP switch to GND
 

dip switch connect at ground

Hi
the given answer is enough.
or if you want a strong pullup then use additional 10k - 33K pull up with controller pin

I have pullup the port b pins with 4.7K & the other side with ground

Is it working for you?
