If you are equipping a classroom, you will be asked this question sooner or later — by a parent, a head of department, or the person signing the purchase order. Raspberry Pi Pico or Arduino?
Both are excellent, both are inexpensive, and both have taught millions of people to make hardware do something. The honest answer is that it depends on your students and your teachers. Here is how we think it through.
The short answer
For most classrooms that want students writing code that controls a robot, we lean towards the Raspberry Pi Pico with MicroPython. For classrooms that already have Arduino experience, or that lean heavily on the existing library of Arduino tutorials and shields, Arduino remains a very sensible choice.
Neither is wrong. The bigger mistake is starting students on a microcontroller before they understand what a circuit is — which is why our first two kits do not use one at all.
Side by side
| Raspberry Pi Pico | Arduino (Uno-style) | |
|---|---|---|
| Main language | MicroPython (C/C++ also possible) | Arduino C/C++ |
| First-program experience | Plug in over USB, save a Python file, it runs | Write a sketch, compile, upload |
| Logic voltage | 3.3 V | 5 V |
| Tutorials and shields | Growing quickly | Enormous, built up over many years |
| Forgiveness of wiring mistakes | Lower — pins are less tolerant of 5 V signals | Higher — a hardier board for beginners |
| Path to text-based coding | Python — the language many schools already teach | C/C++ syntax, a steeper first step |
Why our kits use the Pico
Our Stage 3, 4 and 5 kits are all built around a Raspberry Pi Pico programmed in MicroPython. The reasons are practical rather than ideological:
- Python is already in the curriculum. Many schools teach Python by Grade 8 or 9. Students use the same language for robots that they use for everything else, so the skills carry over.
- Less friction on day one. There is no compile-and-upload step to explain. A student edits a file, saves it, and the robot responds. Faster feedback means more experiments in a 45-minute period.
- It suits the build ladder. Stage 3 sends commands over Bluetooth, Stage 4 reads two IR sensors, Stage 5 reads an ultrasonic sensor and steers a servo. Each step reuses the same board and the same language.
When Arduino is the better call
Choose the Pico if…
- Your students already learn Python
- You want the quickest edit-and-test loop
- You are building toward a graded progression of projects
- Your teachers are more comfortable with Python than C++
Choose Arduino if…
- Your teachers already know it well
- You have existing Arduino kits or shields to reuse
- You want the largest possible pool of online tutorials
- Your students are young and likely to make wiring slips
Experience matters more than the spec sheet. A teacher who is confident with Arduino will run a better lab on Arduino than a nervous one on a "better" board.
Gotchas to plan for
Whichever board you pick, a few things catch classrooms out:
- Voltage levels. The Pico's pins are 3.3 V. Some popular sensors put out 5 V signals, which the Pico's pins are not designed to accept directly. Always check a sensor's output voltage before wiring it up, and follow the build guide for your kit.
- Power for the motors. Neither board should drive motors directly. Motors get their own battery supply through a driver board such as the L298N used in our kits, with a shared ground back to the microcontroller.
- USB cables. A surprising share of "the board is broken" reports are charge-only cables that carry no data. Label your good cables.
How to decide
- Ask what your teachers already know. Confidence in the room outweighs almost everything else.
- Check your existing curriculum. If Python is already in your computing syllabus, the Pico slots in neatly.
- Start with the circuit, not the chip. Beginners should meet switches, motors and batteries first. The microcontroller comes second.
- Buy one, teach one lesson. Before you equip a whole class, run a single session with a single kit and see how it goes.
