Christmas tree with arduino uno
Christmas tree with Arduino UNO
Step 1: Circuit Diagram
The project is super easy for everyone to make, and no specific knowledge is required in order to make it since it is all about controlling RBG LEDs and a Piero buzzer to display the Christmas songs, and all these parts will be placed in one PCB and controlled through an ATmega328 MCU which is the same Microcontroller of the Arduino UNO
The schematic has a Piero buzzer connected to the MCU, which is the main responsible for displaying Christmas songs. The lights blinking will be random while the device is on. the power supply used in this project is a simple 3 lithium battery of 1.5V, which makes 4.5V enough to turn on the MCU.

Step 2: PCB Making
Talking electronics
After making the circuit design I transformed the circuit into a customized PCB design with a tree shape to get a beautiful PCB design when we order our circuit and to do so all I need is to move to PCBWAY the best PCB supplier to get the best PCB manufacturing service, as always just some simple clicks that’s all that you need to upload the appropriate GERBER files of the circuit design then I moved to set some parameters and this time we will use the green color for this PCB since we are producing a tree, so it should be green anyway; just four days after placing the order and my PCBs are on my desktop.

As you can see in the pictures above the PCB is very well manufactured, and I’ve got the same PCB design that we’ve made for our main board and all the labels, logos are there to guide me during the soldering steps. You can also download the Gerber file for this circuit.
Step 3: Ingredients
Before starting soldering the electronic parts, let’s review the components list for our project, so we will need:
★☆★ The necessary components ★☆★
- The PCB that we have ordered from PCBWAY
- One Arduino UNO: https://www.utsource.net/itm/p/8647184.html
- ATmega328p MCU: https://www.utsource.net/itm/p/8972480.html
- RGB LEDs: https://www.utsource.net/itm/p/8664394.html
- 220 Ohm resistors: https://www.utsource.net/itm/p/8664394.html
- 16Mhz oscillator: https://www.utsource.net/itm/p/8664394.html
- Piero buzzer: https://www.utsource.net/itm/p/8664394.html
Step 4: Hardware Assembly

ow, everything is ready so let’s start soldering our electronic components to the PCB, and to do so we need a soldering iron and a solder core wire and an SMD rework station for SMD components.
Safety first
Soldering Iron Never touch the element of the soldering iron….400 °C! Hold wires to be heated with tweezers or clamps. Always return the soldering iron to its stand when not in use. Never put it down on the workbench. Turn the unit off and unplug when not in use. As you can see, using this PCB is so easy due to its very high-quality making and without forgetting the labels that will guide you guys while soldering each component because you will find on the top silk layer a label of each component indicating its placement on the board and this way you will be 100% sure that you will not make any soldering mistakes. I’ve soldered each component to its placement, and you can use both sides of the PCB to solder your electronic components.
Step 5: Software Part & Test
Now we have the PCB ready and all the components soldered very well, so it’s time to move to the software part I have made an Arduino code that you can download for free from the link below now what we need now is to place the MCU in an Arduino UNO board, and we upload the code to the microcontroller then we take it back to its socket on our PCB after that we put the circuit board inside the glass holder, and we glue it.
After placing the batteries, we turn on the device, and we enjoy the sound and the view.
This project is so easy to make and an amazing one, and we recommend it for you if you want to celebrate Christmas your way. But still, some other improvements to perform in our project to make it much more butter, that’s why I will be waiting for your comments to improve it,
