Top Arduino Projects of 2024: Your Dusty Board Might Still Be Salvageable

Hello, fellow makers, geeks, DIY enthusiasts, and those possibly scratching their heads over graduation projects or competitions! Please put down your soldering iron and Dupont wires for a moment. The year 2024 (wait, is it already April 2025? Time flies when debugging!) has passed, and your Arduino board—does it still diligently blink the ancestral Blink LED, or has it evolved to brew coffee and write code for you?

Don’t laugh; I’m not joking. The past year has seen a “surge of activity” in the Arduino projects of 2024. On one hand, the Arduino IDE remains the “leader of the pack,” a spiritual home for many enthusiasts (including those like me who occasionally write bugs and refuse to admit it). On the other hand, Arduino has merged with powerful newcomers like the ESP32, which comes with built-in WiFi/Bluetooth. Sometimes, when discussing Arduino development boards, we might as well be talking about ESP32 development boards.

So today, let’s play the role of “field reporter” and uncover which so-called Arduino projects are the hottest in 2024. Get ready with your little stool and snacks; the editor from Ling Shun Lab is about to take off!

The Self-Evolution of the Definition of “Arduino Projects”

So, at this point in 2024-2025, the connotation of “Arduino projects” has quietly changed. It no longer refers specifically to certain blue or red development boards but has become more of a “spiritual certification”, a vibrant “development ecosystem” centered around the Arduino IDE, compatible with various hardware (especially powerful MCUs represented by the ESP32). It’s less important which hardware is used; what matters is that everyone comes from the “beginner village” of Arduino, using similar “weapons” (IDE and libraries) and speaking a similar “lingo” (code style and community memes).

The Five “Martial Arts Secrets” of Arduino in 2024 (Technical Trend Analysis)

Just watching the excitement isn’t enough; we need to look at the underlying principles. These popular projects reflect several technical directions that the Arduino community is focusing on in 2024. In short, it’s about what everyone loves to play with and what’s trending:

Trend 1: AI Comes Down to Earth, Benefiting All (or Causing Trouble?)

Once upon a time, artificial intelligence (AI) and machine learning (ML) felt like something only those wearing plaid shirts and suffering from severe hair loss could play with on cloud servers. Now? Hah, this trend has reached us, the “common folks” playing with microcontrollers.

Take a look at those Arduino AI projects examples: the previously mentioned AI light, the AI self-driving car that can awkwardly follow lines (or crash into walls), and the AI camera that claims to perform image recognition… there’s even a project teaching you how to control hardware switches with “thoughts” (actually voice recognition). It feels like overnight, if your project doesn’t include some AI functionality, you’d feel embarrassed to greet others, feeling a bit inferior.

Of course, how much of this is real “intelligence,” how much is “artificial stupidity,” or merely a call to a cloud API is subjective. But the undeniable trend is that related tools, libraries (like TensorFlow Lite for Microcontrollers), and hardware with NPUs (look at those AI camera modules) are becoming more accessible and “foolproof,” making us ordinary enthusiasts eager to try and see if we can make our little inventions a bit “smarter”.

However, running models on resource-limited microcontrollers can be painfully slow, making you question life itself, struggling to recognize a cat from a dog, or the training costs being so high that you want to smash your computer. Those who play know the pain. [Consider inserting a humorous image of AI visual recognition failing to identify a cat as a dog]

Trend 2: Robotics Upgrades, Evolving from “Movement” to “Combat”

Robotics has always been the most eye-catching and hardcore area in the Arduino community, and 2024 has taken the term “competition” to the extreme.

The project scope is as broad as you can imagine:

• Childcare/Education: From the crawling MechaMaven to various oddly shaped robots made with 3D printing, to the previously mentioned sophisticated Biddle robotic dog. The goal is to let the next generation (or yourself) learn while playing (or falling into pitfalls).
• Practical/Tool: Various DIY CNC machines, 3D printers, laser engravers, automatic plotters… The goal is to free your hands with technology (or just to prove you can make it).
• Show-off/Creative: Mini FPV drones, ukuleles that can play themselves (with noise), air hockey robots, and cool laser harps… The goal is to impress and harvest likes on social media.
• High-Difficulty Challenges: Self-balancing vehicles (tuning PID to the end of the world), omnidirectional platforms with mecanum wheels, and “beetles” or “Mars rovers” that can walk on complex terrains… The goal is to challenge oneself while showcasing deep knowledge of math and physics (and a sufficient budget).

Technically, 3D printing custom shells and parts has become commonplace, and various sensors (ultrasonic, infrared, cameras, IMUs) are crammed in as much as possible, while control algorithms have evolved from simple logical judgments to more “mystical” fields like PID and path planning.

Looking at these Arduino robotics projects in 2024, it feels like if you want to DIY a decent robot, you need a comprehensive strength in mechanical design, electronic engineering, and software programming. Oh, and most importantly, you need money to buy parts, motors, and batteries… Every time I see those cool robot videos, my first reaction isn’t “Wow, that’s amazing,” but “Ugh… how much did that cost?”

Trend 3: IoT Matures, Saying Goodbye to Youthful Innocence and Learning to “Manage”

The Internet of Things and smart homes have always been a battleground in the Arduino ecosystem (especially after the ESP32 joined). Projects in 2024 show that this field is moving away from the early stage of “just being able to connect to the internet” and is starting to evolve into a more mature, integrated, and… “sustainable” phase.

The main players are firmly on the ESP32 and ESP8266, the “WiFi duo,” as they come with built-in wireless capabilities, making development easier and more cost-effective. The application scenarios are diverse:

• Information Acquisition and Display: Retro radios that can connect to the internet, pixel clocks that display weather forecasts, and display boards that track packages…
• Remote Monitoring and Data Collection: GPS trackers, environmental monitoring stations (temperature, humidity, pressure, air quality), smart trash cans (that tell you when to take out the trash, even if you might not want to know), fire/gas leak alarms…
• Smart Home Integration:This is the main event! Check out those DIY Arduino smart home ideas: the previously mentioned smart energy meter (integrated with Home Assistant), interactive LED cloud lights that can be controlled via a mobile app, remotely switchable sockets, and smart curtain controllers…

In terms of technical implementation, people are no longer satisfied with just creating a simple web server to control an LED. They are starting to play with more professional setups: using MQTT protocol for inter-device messaging, implementing low-power device communication with ESP-NOW, integrating with cloud platforms like Blynk and ThingSpeak for data visualization and remote control, and even exploring how to connect with mainstream smart home systems like Home Assistant and Node-RED. The widespread use of various open-source firmware and libraries (Tasmota, ESPHome, WiFiManager, ArduinoJson) has also significantly reduced development complexity.

Notably, the official Arduino team has also joined the fray, collaborating with Silicon Labs to create a Nano development board that supports the Matter protocol. Matter aims to unify the smart home landscape, ending the current chaotic situation of “everyone sweeping their own doorstep.” It sounds exciting, but it’s uncertain when we DIY players will truly benefit from it, achieving “interconnectivity” (rather than “inter-pitfall”).

Overall, DIY IoT projects in 2024 have fewer flashy gimmicks and more practical uses. They increasingly resemble legitimate products, blurring the lines between DIY and commercial smart home devices.

Trend 4: Interactive Interfaces Going Off the Beaten Path, Aesthetics Matter (Sometimes)

Who says we techies only understand functionality? The popular projects of 2024 have thoroughly challenged this stereotype! Everyone is showcasing their creativity in human-computer interaction methods and aesthetic presentation, emphasizing a “non-conventional” approach.

• Revival of Mechanical Displays: Tired of ordinary screens? Let’s make physical structures move! For example, the Sliding Puzzle Clock that displays time through sliding tiles is a blessing (or nightmare) for mechanical enthusiasts and perfectionists. There’s also the lens clock that creates unique visual effects and the dynamic clock that uses servo motors to indicate time. The core idea is: I refuse to tell you the time in a way you can easily understand!
• LEDs Getting Creative: With LED strips/bulbs being so cheap and useful, how can we just let them blink? Thus, we have interactive LED cloud lights that simulate thunderstorm effects, the previously mentioned cool real-time subway map, various large LED matrices or light cubes (light pollution creators), projection mapping combined with origami art, and even POV (Persistence of Vision) displays utilizing visual persistence principles.
• Wearable Devices Getting Competitive: The functions of smartwatches are piling up (refer to the ESP32 watch with LiDAR), along with BLE data glasses that can display information on lenses via Bluetooth, and the retro DIGIduino watch. The goal is to directly “smear” information on your face or wrist.
• Custom Input Devices: If you find keyboards and mice insufficiently efficient (or not cool enough), then make your own! Modular Macro Keyboards, DIY Stream Controllers (a favorite among streamers), and even a Space Mouse that uses magnetic balls for 3D input. The emphasis is on “my tools, my rules.”

These projects may not always have the highest technical difficulty, but they certainly put a lot of effort into design aesthetics, interactive experience, and visual uniqueness. This reflects an interesting trend: on visually-driven platforms like Instructables and Reddit, whether a project can become popular is increasingly dependent not only on its functionality but also on its “visual appeal,” creativity, and the final presentation effect (how well the photos and videos are shot). After all, tech enthusiasts also need “style” and “likes”!

Trend 5: Environmental Sensing Getting Grounded, Returning from Poetry and Distance to Daily Life

Connecting Arduino to the physical world to sense our surroundings has always been one of the core application directions of the community. In 2024, this trend has not only not weakened but has become more “grounded,” focusing more on solving (or at least quantifying) practical problems in our daily lives.

Projects are blooming everywhere:

• Agricultural/Gardening Automation: Modular hydroponic systems, automatic plant watering devices (this is practically a “periodic” project that pops up every so often), soil moisture monitors… The core demand is to free hands and say goodbye to the title of “plant killer” (though you might still end up killing them).
• Weather and Environmental Monitoring: Various DIY weather stations (measuring temperature, humidity, pressure, light, rainfall, wind speed… practically moving the meteorological bureau home), air quality monitors (PM2.5, CO2, increasing your anxiety), water quality monitors… The core demand is to understand the environment for better survival (or to live in greater anxiety).
• Energy Management: DIY smart energy meters (making you anxious every time you turn on the air conditioning), solar trackers (making solar panels follow the sun like sunflowers), portable solar generators… The core demand is to save money! Be environmentally friendly! Sustainable! (Mainly saving money).
• Practical Tools: GPS positioning and data logging (like recording hiking trails), DIY spectrometers, noise detectors, UV intensity meters… The core demand is to let data speak, satisfying curiosity or specific needs.

Why are these environmental sensing Arduino project ideas so popular? The reason is simple: practical! They often directly address a pain point (like forgetting to water plants, wanting to know if it’s cold outside, or worrying about skyrocketing electricity bills). Moreover, they are relatively easy to implement: sensor modules are cheap and diverse (temperature, humidity, light, soil, GPS, gas, water quality… you name it), connect them to Arduino (or ESP32), and with a bit of coding, you can read the data.

This is probably the application direction where Arduino technology best embodies “technology for humanity” (or “technology for laziness” or “technology for saving money”). It can be expected that as long as we live in this physical world and need to care about our daily needs, such sensor projects that meet practical life demands will always be evergreen in the Arduino application landscape.

Conclusion: Affordable, Open, and Relentless—The Vitality of Arduino Lies in Its Community

Alright, after rambling on for so long, it’s time to wrap it up.

Looking back at the Arduino landscape in 2024 (and early 2025), the feeling is:Old trees sprout new buds, but the new buds seem stronger. On one hand, the classic Arduino spirit—low barriers, easy to start, abundant resources, and an active community—remains the foundation for this ecosystem’s enduring success. It has allowed countless novices to step into the world of hardware DIY.

On the other hand, we must acknowledge that the concept of “Arduino projects” is being continuously broadened and redefined. More powerful hardware platforms (especially the ESP32) have taken a significant share of popular projects, leveraging the Arduino IDE as a springboard. Meanwhile, AI integration, advanced robotics, mature IoT, novel interactions, and environmental sensing are pushing Arduino applications toward more complex, practical, and “competitive” territories.

Looking to the future? I’m not a fortune teller, but based on existing clues, here are a few guesses:

1. AI Will Continue to “Compete”: As toolchains and hardware mature (and prices drop), embedding AI/ML functions into microcontroller projects will become increasingly common, from simple “Hello, little X” to more complex local models, with more variations.
2. IoT Standards Might Open Up Some Possibilities: If the Matter protocol can truly be promoted, it might reduce the awkwardness of our DIY smart home devices “talking past each other,” improving interoperability.
3. Hardware Platforms Will Continue to Evolve: After the ESP32, there will surely be even more powerful chips (like RISC-V architecture?), and people will still find ways to develop them using the Arduino IDE. The official team may also introduce more specialized boards like the Nano Matter for specific application scenarios.
4. Sustainability/Environmental Issues Will Heat Up: Projects related to energy monitoring, solar utilization, and resource management will likely continue to receive attention. After all, saving money is just as important as “saving the planet.”

But in the end, the reason Arduino has come this far and seems poised to continue is not a specific board or a particular IDE version, but that global community filled with millions of creative individuals, eager to share, and always finding new ways to tinker.

It is this continuous collision of ideas, project sharing, and experience exchange (just look at the major forums and Reddit) that allows this ecosystem to absorb fresh blood, adapt to technological changes, and maintain its unique charm in the DIY electronics field.
