It needs to as accuracy as reasonable possible as they don't tell you how close it needs to be as they don't want teams to guess.

Do you have any recommendations on which light sensors are better?  Also, how do I tune light sensors?

Thanks for all your help!

Thanks for the Idea!

Also, are optical sensors the same as light sensors. If so, is there analog expanders so that I could have more then the 15 sensors my mega allows?

Thanks again!

I'm entering into the robofest competition and I need some help. Basically I have to find the area of a black triangle taped onto a white table as quickly & accurately as possible. I'm going to use A=1/2B*a so I need my robot to find the base and the hight of the triangle. 

I know I could use the motor rotations, but I was hoping for a quicker way to get the measurements I need. Could the Arduino use a camera or other sensors so my robot does not have to follow the edge of the triangle?  Also money is not really an object, but I don't know to much programing for Arduino.

Any help would be appreciated!
