Hi, I need a little bit of advice. I work on a school project where robot goes through grid based maze (5x5) and then he sends coordinates of individual squares and obstacles in the squares to the database from which I read them and then I need to draw map of the maze. So my question is, what is the simplest way to make the grid. I thought the easy way would be to just draw 25 rectangles but I don't know if its possible to adjust the thickness of only one side of the rectangle.
