Hi! My name is Richard. I built an elavator out of legos. First I built the pullies. Then I built the frame. Then I built the elevator platform. Then I put more pullies. Then I programmed it. When I first programmed it, it would get stuck at the top. I had to put a bigger block at the top. Then I had to adjust the time to go up and down. Below is a picture and the programming.
