This is my fifth progress report of my passion project. This step is about group all parts and fixing some problems. First we put arduino board to the box and connecting motor wire to arduino board, and connect switch too. Print arm with 3D printer and print sticker. When we test it we have some problems, problems are when the box open, sometimes it open slowly and sometimes the box didn’t open, because motor can’t open the lid, so we add one more motor and fix code.
