Shellminator is an easy-to-use terminal interface library designed for microcontroller environments. Thanks to its low resource usage, it can run on almost any microcontroller. It’s Arduino-compatible out of the box, making it accessible for both hobbyists and beginner programmers.
We’re super proud of this one! It wasn’t easy, but we made it happen. Instead of relying on existing generic libraries (which weren’t flexible enough), we built our own WebSocket and TCP support for ESP8266, ESP32, Raspberry Pi Pico W, and Arduino Uno R4 WiFi.
💡 Bonus: Bluetooth Low Energy (BLE) is now supported for ESP32, Arduino Uno R4, and nRF52840 (Arduino Nano 33 BLE) platforms!
If your device is offline, you can now host the necessary web pages directly from the microcontroller. No external server needed!
If we had to highlight one area where we put tons of effort, it’s the documentation. We knew it wasn’t great before—so we fixed it. Now, it’s interactive, example-rich, and beginner-friendly. Hope you like it! 😊
Totally unnecessary, but super cool! You don’t have to use it, but now you can create progress bars, buttons, selection lists, plots, level meters, and even notifications! 🎨
With wireless support, security became a must. Now, you can password-protect your terminal and keep unwanted fingers away.
A real developer’s terminal isn’t complete without Neofetch! We provide a built-in solution, but feel free to customize it. We can't wait to see your awesome ASCII art in the Show & Tell section! 🎨
With Commander-API evolving, we needed to step up our game. Now, Shellminator plays even better with Commander-API!
Now you can create your own syntax highlighter or use ours, which is fully compatible with the new Commander-API argument parser.
Shellminator reached a critical size where better abstraction was needed. This change made the GUI possible and keeps the project scalable.
We know "refactoring" isn't what you want to hear when it comes to backward compatibility, but trust us, it was worth it.
- Buffering system reworked
- Memory issues in formatting commands fixed
- Performance & scalability improvements
The Shellminator documentation is packed with examples and covers how to use it alongside Commander-API.
💡 Tip: If you're new to Shellminator, go through the examples in order—they build on each other.
🎮 Interactive Demos: Every example comes with a browser-based interactive demo, so you can test things out instantly! No setup needed.
We hope you like it! 😊
