First we began to build the arm. It took us about 3 weeks, coming once every Friday. We enjoyed building it, but towards the end, it started getting confusing. After we finally finished and every thing was right, we hooked it up in the computer. It took a while to figure out how things worked. One of our problems was that the wire got stuck while the arm tried to move left or right. After trying and trying, we finally fixed it. Kaye locked it in above the arm. The ramp where the legos sat was too low, and the hand couldn't pick it up. So we put another lego under it to make it higher. We ran into other little problems, but those were easy to solve when we asked Mr. St. Clair. We finally finished it and it worked when we pushed the button.
Below is a picture and the programming.
