Introduction: 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.
Step 1: Parts List.
For this project you need:
- An Arduino board
- A breadboard
- 3 220 Ω resistors
- 1 buzzer
- 6 LEDs
- 12 male/female cables
- 12 male/male cables
Step 2: Building the Circuit
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.
Step 3: Arduino Code.
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.
Step 4: Making the Christmas Tree
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.
Step 5: Final Result
I assembled the circuit following the Thinkercad sketch then uploaded the program on my Arduino board and here's the result! Enjoy!
