FAQs

Can’t find what you’re looking for? Please contact our friendly team.
How does Code Kit compare to text-based Arduino programming?
Code Kit offers a visual, block-based approach that’s more intuitive for beginners and faster for prototyping. However, it also generates standard Arduino C++ code, helping users transition to text-based programming when they’re ready.
Many experienced makers use Code Kit for rapid prototyping before fine-tuning with traditional coding.
Can I use my existing Arduino libraries with Code Kit?
While Code Kit includes blocks for many popular libraries, you can’t directly import custom libraries. However, users can add custom code blocks, allowing integration of specialised functions. We’re constantly expanding our library support based on user feedback.
Can I use Code Kit offline?
The free web version requires an internet connection. However, Pro users can install our desktop app, which functions fully offline. Your projects sync when you reconnect.
Is there a limit to project complexity in Code Kit?
Code Kit can handle complex projects with hundreds of blocks. However, very large projects may experience slight performance decreases. Pro users benefit from optimised performance in the desktop app for larger projects.
How often do you add new features or blocks?
We release updates multiple times per month, including new blocks and features. Code Kit is continually improving, with Pro users getting early access to exciting new features.
Is there a mobile app version of Code Kit?
While we don’t have a dedicated mobile app, our web version is fully responsive and works well on tablets and smartphones. Pro users can access all features through supported mobile browsers.
How does Code Kit support the transition from block-based to text-based coding?
Code Kit automatically generates clean, readable Arduino C++ code alongside the block workspace. Users can observe in real-time how the code changes as they manipulate blocks, learning fundamental programming concepts like loops, variables, and functions.
This real-time connection between blocks and code, combined with our focus on core programming principles, creates a natural bridge to text-based coding. This makes the transition to text-based coding easier and more intuitive for beginners.
How can I integrate Code Kit with my products?
If you are a company looking to use Code Kit with your products, we ask that you contact us to discuss possible solutions and/or collaborations. Please don’t advertise compatibility with Code Kit before reaching out—it is our goal to ensure each user’s experience is positive and well-designed.
Supported boards
Code Kit supports a wide range of Arduino and Arduino-compatible boards.
