[magical hands]

Hi! to all programmers. I just want to know how can i can display output on my operator interface. For example during the match if i want to display my robot's current gryo_angle or acceleration using external output device how would i do it?
I did some research and I found out that i can buy some LCD's from sparkfun. Can i simply use a laptop do the job? and do i have to connect my laptop to the dashboard port?

If can get little advise on this topic it would be great. Thank You.
