3.4.12: Mblock

For Linux, there is no installable version of mBlock 3.4.12. You must use the web-based version.

It runs smoothly on older computers, making it ideal for schools with limited hardware resources.

Changing graphical blocks automatically updates a side panel displaying the equivalent Arduino C++ code, providing a powerful bridge to text-based coding.

Click on in the top menu bar, hover over Serial Port , and select the corresponding COM port (e.g., COM3, COM4, or /dev/cu.usbserial ). Click on Edit in the menu bar and select Arduino Mode . mblock 3.4.12

Built on the open-source branch of MIT’s Scratch 2.0 offline editor, the interface uses color-coded, interlocking blocks. Students learn foundational software design—including loops, conditional logic, variables, and arrays—without syntax errors. 2. Real-Time Code Translation Window

It is widely remembered as the "workhorse" version for educators and hobbyists using Arduino Uno, Mega, and Makeblock robots before the major architectural shift to web-based standards.

A flagship DIY robotics kit for advanced engineering concepts. For Linux, there is no installable version of mBlock 3

Drag the cap block onto the scripts area. This block acts as the entry point for standalone hardware execution.

Where you drag and drop blocks to build your program. 2. Connecting Your Hardware To control a physical robot or Arduino:

mBlock 3.4.12 is packed with features that made it a cornerstone of coding education: Changing graphical blocks automatically updates a side panel

While mBlock 5 offers web-based interfaces and advanced AI/Python integration, version 3.4.12 remains a staple in many school districts.

While newer versions like mBlock 5 have shifted to modern web layouts based on Scratch 3.0, version 3.4.12 remains highly regarded by educators, makers, and electronics hobbyists. This specific version provides flawless offline performance, predictable driver management, and robust support for legacy hardware, making it a foundational tool for block-based STEAM education.

This creates a natural "stepping stone" that prepares students to transition from visual programming to traditional text-based programming. 3. Rich Hardware Support
