Priodemy releases Labs, a free robotics IDE that runs without an internet connection

Priodemy has released Priodemy Labs, a free Windows application for learning robotics and electronics. It is available now at priodemy.com/labs.

Labs is built around one idea: a student should be able to see the code that their blocks represent. Programs are assembled by dragging blocks for logic, loops, maths, text and variables, and the equivalent Arduino C++ writes itself alongside them as they build. Blocks, Code and Split views mean the transition from one to the other is something a student can watch happen rather than a step they are asked to take on trust.

A simulator, so hardware is not the entry requirement

Programs run on a virtual Arduino inside the application. A wire can be dragged from any component onto any pin, LEDs light as the program runs, and sensor values are plotted live on a serial plotter. A physical board is needed only when a student wants to see the program run on hardware in front of them.

When they do, Labs compiles with a bundled Arduino CLI and uploads over USB. It supports Arduino UNO, Mega and Nano, and the compiler and drivers for those boards ship inside the installer. Support for more boards, including the ESP32, is planned for a later release.

Built for computer labs where the wifi is unreliable

The Arduino toolchain is bundled rather than downloaded on first use, so after installation Labs needs no internet connection and nothing phones home. That is a deliberate design decision rather than a limitation: a school computer lab is frequently the place where a browser-based tool is least usable.

There is no account to create inside the application, no licence key and no seat limit, so a school can install it on every machine in a lab at no cost. Three experience levels — Explorer, Builder and Engineer — change how much of the interface is shown, so the same application suits a beginner and a student building a final-year project.

What is included

• Drag-and-drop block editor with live Arduino C++ generation
• Built-in circuit simulator with drag-to-rewire and a live serial plotter
• Upload to real hardware over USB using a bundled Arduino CLI
• Arduino UNO, Mega and Nano supported offline
• Four worked examples — LED Blink, Traffic Light, Light Sensor and Bluetooth Hello
• Explorer, Builder and Engineer interface levels

Availability

Priodemy Labs version 1.0.0 runs on Windows 10 and 11, 64-bit. The standard build is about 80 MB. An optional larger build of about 1 GB adds an AI assistant that answers questions about the student’s own code and runs entirely on the machine itself, so no code or question leaves it; the size difference is the language model. Labs is not yet available for macOS or Linux.

The download asks for a name, an email address and a role so that Priodemy can send updates and fixes. It does not ask for a phone number.

“Most robotics teaching stops at the blocks, and the student never finds out that the blocks were code all along. Showing both at once, on a simulator that works when the internet does not, removes two of the reasons a school lab gives up on the subject.”
