This project was made to be an interactive Christmas decoration, the tree LEDs, music played and the arms of Santa and Elf are all controlled using a phone app created using MIT App Inventor that communicates with the Arduino MKR1000.
First I made a cone shaped paper and painted it green.
Then I have added green cardboard to create leaves of the tree.
Then creating white snow effect using white cardboard.
Soldering LED lines I have made three lines:
Creating the star on top of the tree.
Then I have used gift paper to make gifts under the tree.
I have cut down the shapes of both Santa and Elf and connected servo motors to each arm of them.
Added some decoration white paper to the table and red ribbon on the tree.
