7 Arduino Christmas Projects You Can Make This Year

0 281

Maybe you received an Arduino starter kit as a gift recently, or maybe you keep hearing about this awesome hobby for tinkerers and you want to get a taste, or maybe you’re an Arduino pro who just needs some fun ideas for the holiday season. If so, you’ve come to the right place.

Everyone should learn a bit of Arduino, and these project ideas are great examples of what you can do with just a bit of knowledge and guidance. Here are seven ways to spruce up your Christmas this year, ranging from beginner-friendly to impressively complex.

1. Motion-Activated Greeting Wreath

This simple project can be a great way to set the mood when visitors come over for the holidays. Using a motion sensor and set within a wreath hanging, it plays a pre-recorded message followed by a random Christmas song.

It may take a few hours to create and set up, but the instructions are straightforward and there’s nothing particularly tricky about it; the assembly is easy and the code is painless. A good place to start for absolute beginners who want to level up their skills.

2. Advent Candle

This Arduino advent candle has 25 LED lights, one for each December day leading up to Christmas, and a cool effect to show which day you’re currently on. It also has a button that plays “Jingle Bells” when pressed. Ideally you’d make it in November and have it done by the 30th, but it’s still worth making even if you’re late.

This project requires a bit of soldering, which can be daunting if you’ve never done it before. But don’t worry: we have a great guide for learning how to solder!

3. Musical Fairy Lights

In this beginner-friendly project, you string together numerous LED lights to create a fairy lights decoration where each light randomly flickers on and off. It’s a wonderful project for building atmosphere. The lights are simple, but really work to bring the feeling of Christmas.

The best part? It’s not just instructions but an actual tutorial. You’ll learn things, making it great for absolute beginners. If you aren’t the least bit comfortable, start with our complete guide to Arduino and our article on Arduino beginner mistakes to avoid. It also involves a bit of soldering, so consult the article above on learning how to solder.

4. Christmas Tree Centerpiece

If you live in a small studio or apartment, a full-blown Christmas may be out of the picture. But you can still go for something more compact! Like this Arduino Christmas Tree, which automatically lights up when the ambient light drops below your pre-defined value.

Because of how small this project is, you can put it almost anywhere: coffee table centerpiece, entryway side table, bedroom nightstand, kitchen countertop, etc. You’ll need to work with wood though, so check out our article on learning rudimentary woodworking skills first.

5. Alexa-Powered Christmas Tree

On top of all the creative uses for Amazon Echo and Alexa, did you know that it can integrate with Arduino as well? An Arduino Yun running Linino OS can comprehend Alexa voice commands and consequently control components, such as the LED strand used in this project.

In short, you can now control the lights on your Christmas tree with voice commands! It’s admittedly an involved project, but isn’t so difficult that you’ll rip your hair out over it. If you have experience with Arduino and Amazon AWS, you should definitely give this a try.

6. Christmas Light Show

In this awesome tutorial by Akshay James, you’ll learn how to create a light show using the lights and decorations mounted on the exterior of your home, and that light show will be synchronized to music. It can even integrate fog machines if you wish.

The project utilizes MIDI for music, and the MIDI signals are interpreted by an Arduino to turn relays on and off, which is what controls the various lights for the show. It isn’t easy, but the results are so worth it, as you can see in the video above.

7. Huge Christmas Wall Decor

If you have a lot of time on your hands — we’re talking days — and want to tackle a project that’s more complex than it may seem on the surface, then this wall hanging may be the perfect choice. It captures the essence of Christmas, has a lot of moving parts, and is able to make any room come alive.

You’ll be working with a lot of wood, some laser cutting, and a good bit of DIY hacking of various components. The creator himself says that it took him almost a week to make this, so prepare to set aside as much time, if not more! At least once it’s made, you can store it away and effortlessly bust it out every Christmas.
