mBlock was developed by Makeblock to address this gap. Derived from the open-source code of Scratch 2.0, mBlock allowed users to program Arduino-based robots (such as the mBot) using the familiar block-based interface. Version 3.4.12 represents the mature stage of the Scratch 2.0-based lineage before Makeblock transitioned to the web-based Scratch 3.0 architecture (mBlock 5). This paper posits that mBlock 3.4.12 remains a subject of technical interest due to its specific "hybrid" coding capabilities and its stability on legacy systems.
mBlock 3.4.12 is a legacy release in the mBlock 3 (Scratch-based) product line produced by Makeblock. It’s a desktop application (Windows and macOS) used for block-based graphical programming, robotics control, and Arduino-style text programming. Version 3.4.12 is primarily intended for educational users working with Makeblock hardware (mBot, Ranger, Airblock, etc.) and Arduino-compatible boards. mblock 3.4.12
Because this software is based on Flash (which Adobe killed in 2020), installation is slightly different than modern apps. Follow this guide carefully. mBlock was developed by Makeblock to address this gap
Community repositories: GitHub has "mBlock 3 extensions" from 2016-2018. They still work flawlessly. This paper posits that mBlock 3
