Hi, questions to all the guru out there. I have spent 20 hours on this roboarm. I am hoping to make it work like a color sorter. - pick up a ball wrapped in tin foil and drop it off at a container wrapped up in tin foil as well. - pick up a ball wrapped in black tape and drop it off at a container wrapped up in black tape. I was hoping that the tin foil can produce a much lighter value as it should reflect the light from the light sensor, but it does not. I guees I have to use white tape instead of the tin foil. Meanwhile, I am hoping that I can add in another color, instead of just white & black. Any suggestion? Thanks in advance!!! -- Elizabeth Mabrey -- MIME ATTACHMENTS DISCARDED: 1.
