Problem with output (by Pranjal Maheshwari)

Hey, i am using pic16f877a i am getting a different output level for false condition. I have made a simple program to check that. when ever i press a button i should get '1' i.e. 5v at output this is working properly. but when i release the button instead of getting 0v at output side I am getting a voltage of about 2.5 volts and it keeps on fluctuating. How can I overcome this problem. without overcoming this problem i cannot continue further with my project.

Hello Pranjal,
try other microcontroller pins, make sure and use the resistor input pin to ground (pull down resistor).

Thank you for the help. It really worked, the pull down resistor was the problem.
