How to give sudo access to a bash script?

I have a bash script(chbr.sh) to change my display brightness from terminal as my brightness keys doesn't work.

`sudo setpci -s 00:02.0 F4.B=30`

Now, every time I run that script it asks for password which I don't like. So, I googled a little and found out that one can edit /etc/sudoers file to disable the password feature.

So, I edited my sudoers file with the below content

ronnie ALL = (ALL) NOPASSWD: /home/ronnie/chbr.sh

Now when I run my script as ./chbr.sh it again asks for my password. So, is this not the right way to give sudo access to a bash script or what am I doing wrong here.

ronnie@ronnie:~$ ls -l chbr.sh
~rwxrwxr-x 1 ronnie ronnie 46 Jul 13 15:59 /home/ronnie/chbr.sh
sudoers sudo bash

For anyone who stumbles into this old forum. You don't need sudo to change the brightness. It can be done with the “light” program where the 

light -A 5

increases brightness with 5 and 

light -U 5

decreases the brightness with 5.
