Story

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.
