Funduino Cube, Arduino-compatible learning system & development board
This goes with it
Description
Funduino Cube
Your project doesn't fail because of the code.
It fails at the setup.
You know the situation. An hour in the evening. Get out the breadboard, get out the jumper wires, find the sensor. The first upload fails - but is it the code or the loose cable on pin 7? Two hours of troubleshooting later, the session is over and the project ends up in the corner.
It's not your fault. The old system is the problem.
Makers don't fail because of logic. They lose momentum because of problems before the first working result: wiring errors, unstable setups, and the endless question: code or hardware?
The Funduino Cube eliminates these problems completely. 13 permanently soldered modules. No jumpers, no breadboard, no loose connection as a source of errors. Plug in USB and your code produces a visible response immediately.

The Mounted Module System
Hardware eliminated as a source of errors
Classic kits provide individual parts. You wire them, plug them in, and hope. When something doesn't work, you never know whether the error is in the code or in a loose cable. This costs time, nerves, and ultimately the entire project.
The Funduino Cube solves this with a single design principle: All 13 modules are permanently soldered, integrated directly onto the circuit board, and ready to use immediately. Hardware is no longer a variable. If your code doesn't work, the code is the problem - and that's exactly what makes debugging a real learning moment.
No wiring chaos
No jumper wires, no breadboard, no unstable connections. The Cube is ready to use from the very first moment.
Immediate visible response
LED lights up, sensor measures, display shows - in under a minute, you see what your code does in the real world.
Reproducible results
Not a lucky hit. The hardware is stable, and your results can be reproduced at any time - making real learning possible in the first place.

20-hour learning path
From the first blink to your own project - structured, not random
No tutorial hopping. No YouTube chaos. 13 lessons, building on one another, each explained in a video. You always know where you are and what comes next.
Control LEDs, read buttons, and create your first logic - using blocks or directly in C++. After Lesson 1, you'll see how your code triggers a physical reaction. This is the moment that turns typing into real programming.
Ultrasonic sensor, motion detection, servo motor, IR remote control, LED ring, display. Each module builds on the previous one. By the end of this phase, you will be programming complex interactions between multiple modules.
Tilt sensor, temperature & humidity, potentiometer as input. Use modules together and develop your own logic – no more tutorial chaos.
3 external ports. Plug in an ESP32 or Pi Pico adapter. Connect your own sensors. What you learn on the Cube transfers 1:1 to your own circuits – the Cube is not an endpoint; it is the cleanest starting point.
Two paths, one hardware platform
Start with blocks. Switch to real code. No new board.
The most common beginner mistake: committing to one option too early. The Cube enables both – and you can switch at any time without changing systems. Each option has its own YouTube playlist with all 13 lessons.

13 integrated modules
Everything permanently soldered. Everything ready to use immediately. No preparation time.
No sorting, no searching, no plugging things together. All 13 modules are there – from Lesson 1 to your own project.


Available in red, yellow, and green. They serve as indicators and are ideal, for example, for building a traffic light circuit or as signal indicators for your sensors.

With a push button, you send input signals to your microcontroller. Push buttons are widespread and encountered on our everyday journeys to school or work, for example at traffic lights.

The motion sensor detects movement within a fixed detection radius. It is suitable, for example, for building an alarm system or as a trigger for a wildlife camera.

Speakers, also called speakers, buzzers, or sounders, serve as acoustic signal generators. They indicate with a short or long beep that a process has started or ended. On the Funduino Cube, they can also be used to generate melodies.

The HC-SR04 can measure distances between 2 and 300 centimeters. The ultrasonic sensor is one of the classics of Arduino microelectronics and must not be missing from the Funduino Cube.

With a WS2812B ring, you can display up to 16,777,216 colors. The clever part: All the ring's LEDs can be controlled individually - a real eye-catcher.

The MG90S servomotor is controlled via a PWM signal. This type of control enables precise control of the rotation axis by angle.

In combination with the Funduino remote control, this sensor detects and processes signals from a greater distance - just like from your couch at home.

With a photoresistor, you can determine the light exposure of your Funduino Cube. This allows you to implement effective day and night circuits.

A potentiometer is a variable resistor. You can use it, for example, to precisely control the brightness of an LED.

What would a development board be without a proper display? With the 0.96″ OLED, your Funduino Cube has a freely configurable display module that can show you humidity, temperature, brightness, the X, Y, and Z axis positions, and much more on request.

One of the highlights of the Funduino Cube: With the MPU6050 accelerometer and gyroscope, you can precisely determine the X, Y, and Z position of your Cube. Comparable modules are often used in RC model building, for example to monitor the orientation of aircraft.

The DHT11 measures humidity and ambient temperature. It is one of the best-known modules in DIY electronics and is often used in hobby weather stations or for monitoring temperatures in hard-to-reach places.

Use your own sensors, actuators, and modules directly on the Cube via the 3 simultaneously usable external ports. Ideal for makers: test prototypes before your own circuit board arrives.
For beginners: immediate results
Each module has its own video lesson. You start from zero and see after the first session how your code makes real things move. This feedback loop keeps motivation high, whereas other setups would have drained it long ago.
For makers: rapid prototyping
All modules are ready to use immediately, with no setup. Test, combine, and iterate on ideas - without spending 20 minutes wiring up a breadboard first. The Cube is your personal lab before your own PCB.
What you can build next
Learn with the Cube - then build your own projects
Most people underestimate what becomes possible after getting started. With the knowledge from the Cube, you no longer build mere gimmicks, but real systems that solve real problems.

Automatic plant watering
A moisture sensor in the soil continuously measures whether the plant needs water. If the value falls below a defined threshold, a water pump starts automatically. Your first system that really works - and one you can see every day.

Alarm system with motion detector
The motion detector detects intruders, the buzzer sounds the alarm, and the LED ring flashes red. The system is modular - and that is exactly what makes it exciting: Once you understand it, you can expand it step by step. Add a camera module, app notifications via ESP32, or an infrared camera for night mode. A simple project becomes a real home security solution.

Mini weather station with Wi-Fi
The DHT11 measures temperature and humidity, the OLED displays the values locally - and the station sends the data via Wi-Fi to an app or dashboard through the ESP32 adapter. This lets you see the weather at home from anywhere. This is no longer an experiment; it is a real IoT device.
- RC vehicle with infrared controlThe remote control directly controls motors - a classic maker project with a high wow factor and lots of learning potential for motor control.
- Automatic terrarium systemTemperature, light, and humidity are automatically monitored and regulated - for reptiles, plants, or insects. Extremely useful for animal owners.
- Automatic roller shutter controlThe LDR measures the brightness outside, and the servo motor automatically opens or closes the roller shutter. Directly useful in everyday life - without an expensive smart home system.
-
Reaction gameAn LED lights up at random, the button must be pressed as quickly as possible, and the display shows the reaction time. It's fun, impresses others - and shows how much is possible with just a few components.
