La Raspberry Pi Pico and Pico W They've opened the door to a ton of cheap, small, and very effective DIY projects. While many people first think of the "big" Raspberry Pi, the truth is that this microcontroller is perfect for learning electronics, controlling sensors, creating useful little gadgets, and even setting up systems connected to the internet or long-range networks like LoRaWAN.
If you're looking for Raspberry Pi Pico project ideas Looking for projects that go beyond the typical blinking LED experiment and are truly useful in everyday life? Here you'll find a wide range of options. From highly practical uses (automation, home automation, data measurement, lightweight servers) to more creative and entertaining projects, with clear explanations, difficulty levels, and typical components you'll need.
Raspberry Pi Pico, LoRaWAN and long-range projects
One of the areas where Pico shines is in the low-power connectivityThe LoRaWAN protocol allows data to be sent over distances of several kilometers while consuming very little energy, ideal for remote sensors or field projects where you don't want to be changing batteries every two days.
With LoRaWAN you can achieve ranges on the order of 10-15 km Under favorable conditions, but with a significant drawback: the transmission speed is extremely low, we're talking about just a few bytes per second. This isn't suitable for sending video or audio, but it's perfect for sending temperature and humidity readings, tank status, approximate location, simple alerts, and so on.
Another condition is that you must be within the coverage area of a existing LoRaWAN network (for example, The Things Network or private deployments), or set up your own gateway. The good news is that the global community around LoRaWAN is very active, and there's plenty of documentation, examples, and deployed nodes, so you rarely go in completely blind.
Thanks to the work of community developers, the Raspberry Pi Pico has become Compatible with very popular LoRa librariesA relevant example is the LoRa library for Arduino maintained by Sandeep Mistry, which has been extended to also support the Pico. This makes life much easier, because you can take advantage of existing examples and adapt the code to your project without starting from scratch.
To equip your LoRaWAN Pickaxe you need a LoRa radio breakout or module (for example, based on SX1276/SX1278) that connects to the microcontroller's pins. Then, using MicroPython or C/C++ and the corresponding library, you configure your LoRaWAN network credentials (devEUI, appEUI, appKey, or equivalents), and you have a node ready to send sensor data over long distances.
First useful projects with Raspberry Pi Pico and Pico W
The Raspberry Pi Pico is designed to control and lightweight electronics projectsThe Pico W adds Wi-Fi, opening up even more possibilities. Whether you're just starting out with electronics or you're already proficient at soldering and using breadboards, you can tackle simple yet practical projects.
For those who receive a Pico almost by surprise, without yet having hobby electronics “arsenal” (breadboard, jumper wires, LEDs, sensors, etc.), it can be a good idea to start with projects that require very few external components or that are mainly based on the use of Wi-Fi and some integrated LEDs. Once you have basic materials, you can gradually increase the complexity.
If you already have some experience with welding and assembly, the Pico allows you to consider more ambitious and permanent projects, such as monitoring systems, small robots, addressable LED lighting controllers, or IoT devices that communicate with a more powerful home server, such as a Raspberry Pi 4 or 5.
The idea is that your first personal project doesn't just remain a curiosity. It's interesting that it has some practical use, even if it's simple: turning on lights, monitoring a door, measuring the temperature of a room, displaying messages on a screen, or collecting data from your environment to learn how to process it later.
In parallel, you can use the "large" Raspberry Pis for server, multimedia, home automation, or emulation projects, and leave the Pico for the other part. hardware and sensor controlTogether they make a great team in any IoT or home automation project.
Practical project ideas with Raspberry Pi Pico
The variety of possible projects with Pico is enormous, but there are some categories that fit especially well with its characteristics: low power consumption, small size and ease of programming with MicroPython or C/C++.
A classic option is to create a addressable LED light controller using WS2812B (NeoPixel) type strips. The Pico is responsible for generating the color patterns, musical effects or ambient scenes, and you can use buttons or a small web server on the Pico W to change modes from your mobile phone.
Another very common possibility is to set up a mini weather station Based on sensors such as the BME280 or DHT22 connected to the Pico, this captures temperature, humidity, and pressure, and the data can be displayed on a small OLED screen, be sent via Wi-Fi to a control panel (like Grafana) or even sent via LoRaWAN if you want to measure the weather in a remote location.
If you like the idea of caring for your plants, the Pico is perfect for a system of simple automatic irrigation. With a soil moisture sensorWith a relay and a small pump, you can water potted plants or a small garden based on the actual soil moisture level. This is not only convenient, but it also helps save water and keep plants healthier.
The Pico can also function as “child” of a larger Raspberry Pi in home automation projects. For example, Home Assistant running on a Pi 4 can communicate with Pi chips distributed throughout the house to activate relays. read sensors or control LED strips using lightweight protocols like MQTT. This way you separate the "heavy" automation part from the low-level control part.
For portable projects, the Pico's low power demand makes it ideal for gadgets powered by LiPo batteries or cellsFrom small data loggers that store information on a microSD card, to devices that wake up periodically, measure something, and go back to sleep to last for months without recharging.
Star projects with the "big" Raspberry Pi that you can complement with Pico
While the Pico focuses on control tasks, the Raspberry Pi 3, 4, or 5 handle the rest. heavier projects that require a full operating system, a robust network, fast USB, or video output. Many of these projects can be further enhanced by integrating the Pico as a sensor or actuator node.
A very popular example is transforming your Pi into a multimedia center Using Kodi or Plex. With a Raspberry Pi 3B+, 4 or 5, a decent microSD card and an HDMI cable, you can turn your TV into a complete “smart TV”, with access to series, movies, music and photos, from local storage or compatible streaming services.
For those who want environmental data, a more powerful Raspberry Pi can record and display what They send several Pico units. indoors or outdoors (temperature, humidity, air quality, rainfall, wind, etc.). All of this is stored in time series databases like InfluxDB and displayed on panels with Grafana, creating a very complete weather station.
Another interesting combination: a Pi 4 with OpenMediaVault as NAS server and several Pico boards as remote nodes that upload logs, sensor backups, or data generated in the field. This way you set up a personal cloud that centralizes what your microcontrollers produce. You only need a Pi 4 or 5, USB hard drives (HDD or SSD), a good power supply, and wired network.
In the area of security, a Raspberry Pi with MotionEyeOS or software like Motion can act as surveillance camera with motion detectionMeanwhile, the Pico, located in doors or windows, provides PIR sensors, magnetic switches or local sound or light alerts when something is activated.
If you like retro gaming, the Pi (not the Pico) is the one that will run RetroPie and other emulators to set up a classic console emulatorThe Pico, on the other hand, can be used as a custom USB controller or interface for arcade buttonsgiving the arcade a more "maker" touch.
Servers and home services with Raspberry Pi
Once you get a taste for the Raspberry Pi, it's common to want to build permanent servers at home that operate 24/7 with minimal power consumption. These functions typically go beyond what a Pico can do and are better suited to a Pi 3, 4, or 5.
One very rewarding project is converting the Pi into a NAS server With OpenMediaVault or Samba, all you need is a Raspberry Pi 4 or 5, USB hard drives (HDD or SSD), a good power supply, and a wired network connection. This lets you create your own personal cloud for backups, photo and video storage, and even streaming media to other devices.
Another very popular service is Pi-hole, which transforms the Raspberry Pi into a ad blocker and trackers at the network level. By acting as a filtering DNS server, all devices connected to the router (computers, mobiles, tablets, smart TVs) benefit from cleaner pages, faster loading, and a bit more privacy.
For advanced home automation, Home Assistant running on a Raspberry Pi has become a standard. It serves as central brain of your smart homeintegrating lights, plugs, sensors, cameras, and other devices from countless brands. From there, you create complex automations such as "if I detect movement and it's nighttime, I turn on the lights," or "if no one is home, I lower the heating."
If you have a 3D printer, installing OctoPrint on a Pi will allow you to control and monitor your printouts via the web, without having to leave the PC on or be next to the machine. It is possible to add a webcam to see the progress and generate very attractive time-lapses of the pieces under construction.
Beyond these flagship projects, the Raspberry Pi can act as a LAMP/LEMP web server, a personal VPN node with WireGuard or OpenVPN, a distributed computing learning cluster, a Minecraft server, an internet radio station, or an IoT visualization dashboard with Grafana and InfluxDB, among many other things. network-oriented uses and services.
Robotics, vision and interactive projects
The combination of a Raspberry Pi with an operating system and a Pico as a slave microcontroller is very powerful for robotics and physical interaction projectsEach one takes care of what she does best.
For a mobile robot, the mechanical part usually includes a chassis with wheelsDC or stepper motors and a controller such as the L298N or DRV8833. The Raspberry Pi can handle the "high" logic: remote control via Wi-Fi or Bluetooth, web interface, camera processing, etc. The Pico, in parallel, handles the fine motor control and fast sensor readings.
With ultrasonic sensors like the HC-SR04, a line sensor, or infrared sensors, your robot can avoid obstacles, follow routes, or navigate mazesThe Pico will process these signals in real time, while the Pi makes more complex decisions, such as deciding destinations, mapping the environment, or communicating with other systems.
In the field of computer vision, the Raspberry Pi can use OpenCV to do basic motion detection or face recognitionusing the official camera or a USB webcam. The result of the analysis (for example, “person detected”) can be sent to a Pico to activate lights, servos, or any other type of physical actuator.
You can also build interactive devices like smart mirrors, information panels, or LED displays. The Pi handles the graphical interface, weather, news, calendar, and other APIs, while the Pico takes care of... control LED strips, physical buttons and sensors which provide interaction to the invention without overloading the main Raspberry Pi.
For video game and gadget enthusiasts, there is the option of building one desktop arcade machine or portable consoleThe Pi runs the emulators and the interface, and the Pico manages the matrix keypad, joysticks, pushbuttons and RGB lighting of the controllers, working as a USB interface or serial communication with the Pi.
Costs, materials and level of difficulty
A common question when starting out is how much you'll have to spend. The great thing about the Raspberry Pi family is that The plates are quite affordable compared to commercial equipment that does similar things, and many projects only need a few extra components.
The Raspberry Pi Pico is in a very low price range, ideal for building multiple distributed nodesIf you add a breadboard, jumper wires, some LEDs, resistors, and a couple of basic sensors, you'll have plenty of material for experiments. As you progress, you can add relays, displays, servos, or wireless communication modules.
The Raspberry Pi 4 or 5 are more expensive, especially if you add a good microSD card or SSD, case, and quality power supplyIn return, you get a general purpose platform with which to set up NAS servers, multimedia systems, home automation or emulation without paying for licenses or subscriptions.
Regarding the level of difficulty, there are really simple projects, like a Pi-hole blocker or a media center with Kodi, and others that are much more demanding, such as a computing cluster, a well-designed smart mirror, or a facial recognition system. The sensible thing to do is start with affordable projects that motivate you, and gradually climb the ladder as you master Linux, Python, and basic electronics.
The total cost also varies with the accessories: a complete weather station with rain, wind, and air quality sensors will obviously be more expensive than a simple thermometer connected to the Pico, and a NAS with several high-capacity drives is significantly more expensive than a small home web server. Even so, the DIY approach with Raspberry Pi is usually worthwhile. much more economical and flexible than buying closed commercial solutions.
Learning, community, and resources to keep moving forward
One of the great advantages of working with Raspberry Pi and Pico is that you're not alone. There's a gigantic global community It's a community of users who selflessly share projects, tutorials, code, and help, for both beginners and advanced users.
If you get stuck at any point, official Raspberry Pi forums, Reddit communities dedicated to the board, Home Assistant, 3D printers, or IoT projects, as well as specialized blogs and YouTube channels, are constant sources of help. practical examples and solutions to problemsThe clearer your question (motherboard model, system version, what you've already tried), the easier it will be to get help.
To learn how to get the most out of the Pico, it's highly recommended to experiment with it. MicroPython and C/C++Since most official and community examples rely on these languages, starting with simple exercises (digital inputs, PWM to control LED brightness or motor speed, reading analog or I2C sensors) will give you a foundation for tackling more serious IoT projects.
For the Raspberry Pi with an operating system, Python is also king, but it's not the only one. You can learn to set up web servers, manage Linux services, use Docker to encapsulate applications, and explore tools like Grafana, InfluxDB, Home Assistant, or OpenMediaVault, which appear frequently in projects. automation, monitoring and storage.
Over time, you'll discover that almost any idea you come up with has already been tried by someone with a Raspberry Pi. That doesn't mean you should simply copy it, but rather that you can consider it as a starting point. starting point and adapt it to your needsAdding your personal touch, combining several projects, or leveraging your previous experience in other fields.
Ultimately, the beauty of the Raspberry Pi Pico and the more powerful Raspberry Pi models is that they allow you to turn ideas into something physical and functional with very few resources, learn programming, electronics, and systems at the same time, and build an ecosystem of projects that support each other: from the Pico that measures the soil of your plants to the Pi that stores the data, displays it on a panel, and sends you notifications to your mobile phone when it's time to water.
