Arduino Music and Lights Christmas Tree

This is one of my first Arduino projects, it's a Christmas tree that plays Jingle Bells song synchronized with Leds that goes on and off.

For this project you need:

1. An Arduino board
2. A breadboard
3. 3 220 Ω resistors
4. 1 buzzer
5. 6 LEDs
6. 12 male/female cables
7. 12 male/male cables

To design the circuit I used Thinkercad, this free program helps me every time I need to design circuits.

Build the circuit copying the wiring from the image.

In this code the first part commands the sound of the buzzer and the lighting of the LEDs, the second part manages the sound of the notes.

To make the Christmas tree I used some scrap plywood.

I drew a cardboard shape then I transferred it to the wood surface, and then I cut the profile using a jigsaw.

For the holes that hold the LEDs, I used a drill with 5 millimeters drillbit.

I assembled the circuit following the Thinkercad sketch then uploaded the program on my Arduino board and here's the result! Enjoy!
