Learn robotics by building it.
Drag blocks together and watch real Arduino code write itself. Run it on a virtual board, then plug in a real one and watch the same program light up in your hand.
Free for Windows. No account, no licence key, and no internet needed once it is installed.
Blocks in, working hardware out
Four steps, and the student can stop at any of them. Plenty of classes never get past the simulator — that is a complete lesson on its own.
Drag blocks
Snap together logic, loops, maths, text and variables. No syntax to memorise, nothing to spell wrong.
Watch the code appear
Real Arduino C++ writes itself beside your blocks as you build. Blocks, Code and Split views — so the code stops being a mystery.
Simulate it
Run the program on a virtual Arduino. Drag a wire from any component onto any pin, watch LEDs light, and plot sensor values live. No hardware needed.
Upload to real hardware
Plug in an Arduino, pick the port and press Upload. It compiles with a bundled Arduino CLI and runs on the board in front of you.
Designed around how schools actually work
Works with no internet
The Arduino toolchain is bundled. After install, nothing phones home — which matters in a school lab where the wifi is a rumour.
Free, and no account
No sign-up inside the app, no licence key, no seat limits. Install it on every machine in the lab.
Grows with the student
Explorer, Builder and Engineer levels change how much of the IDE is shown, so the same tool suits Class 6 and a final-year project.
An AI tutor that runs offline
The optional full build bundles a local language model. It answers questions about your code on the machine itself — no data leaves it.
Four worked examples come with it
Each opens as an editable copy, so a student can take it apart without breaking the original. All four run on an Arduino UNO.
LED Blink
Blink the on-board LED once per second.
Traffic Light
Cycle red → green → yellow LEDs with blocks.
Light Sensor
Read an LDR on A0 and print the value.
Bluetooth Hello
Send a message over an HC-05 module.
More arrive as the block library grows — servo, ultrasonic and temperature examples need hardware blocks that are still being built.

Frequently asked
Is it really free?
Yes. Priodemy Labs is free to download and use, with no account, licence key or seat limit. Install it on as many school or home machines as you like.
Which boards does it support?
Arduino UNO, Mega and Nano. The compiler and drivers for these are bundled, so they work with no internet connection. More boards, including ESP32, are planned for a later release.
Do I need an Arduino to use it?
No. The built-in simulator runs your program on a virtual board, with wiring you can drag and a live serial plotter. A real board is only needed when you want to see it run on hardware.
What are the system requirements?
Windows 10 or 11, 64-bit. The standard build is about 80 MB to download; the optional build with the offline AI assistant is about 1 GB because it includes the language model itself.
Does it work on Mac or Linux?
Not yet. Priodemy Labs is Windows-only today, because that is what the school computer labs we build for actually run.
Why do you ask for my details before the download?
So we know who is using Labs and can tell you about updates and fixes. We ask for a name, an email and your role — nothing else, and never a phone number. See our privacy policy for how it is handled.
Can our school use this in a computer lab?
Yes, and that is what it was built for. There is no per-seat cost. If you would like help setting it up across a lab, or want it alongside Priodemy EduSuite, get in touch.
Part of the Priodemy ecosystem
Labs is the hands-on end of what we build. There is a free Robotics course on the site to learn alongside it, and schools can pair Labs with Priodemy EduSuite.
