Mblock 3.4.12 ((exclusive)) Jun 2026

Additionally, because the software is based on Scratch 2.0, it inherits its extension capabilities, allowing support for third-party robotic products like Lego or LittleBits.

Drag and drop standard command blocks underneath this definition to build your custom feature.

A 3-in-1 educational robot kit for advanced building and coding.

mBlock 3.4.12: The Timeless Graphical Programming Tool for STEM Education mblock 3.4.12

Connect your hardware to the computer's USB port using an appropriate data cable. Ensure the robot or board is powered . 3. Select the Serial Port

As a legacy app, you will encounter hurdles. Here are the fixes for the top three complaints.

What or robot kit you are connecting (e.g., mBot, Arduino Uno)? What operating system your computer uses? Additionally, because the software is based on Scratch 2

void loop() if (digitalRead(sensorLeft) == 1) motorRun(1, -150); motorRun(2, 150); else if ...

mBlock 3.4.12 remains one of the most reliable legacy software versions for introducing students to robotics, physical computing, and graphical programming. Based on MIT’s Scratch 2.0 open-source code, this specific version bridges the gap between visual block-based coding and real-world hardware like Arduino boards and Makeblock robots.

The software functions completely local, preventing bandwidth bottlenecks in classrooms. mBlock 3

This immediate code view is the pedagogical secret of mBlock 3.4.12.

Because it is offline, it is not subject to internet connectivity issues during class.

To understand the value of , we must rewind to the mid-2010s. At that time, Scratch 2.0 was the king of visual programming for kids. However, Scratch had a massive limitation: it could not talk to hardware. You couldn’t blink an LED or move a servo motor using vanilla Scratch.
