Mblock 3.4.12 //top\\ ✅
Drag "When mBot starts up" (from the Robots tab) and attach motor control blocks to make the robot move. Educational Applications of mBlock 3.4.12 mBlock 3.4.12 is widely used in STEM curricula to teach: Algorithms: Logic flow and sequencing. Robotics: Controlling motors, LEDs, and sensors.
Add one final wait (1) secs block at the bottom of the loop sequence. Step 3: Connect and Upload Connect your Arduino Uno to your computer via a USB cable.
is one of the most stable legacy versions of the popular graphical programming software developed by Makeblock. Based on Scratch 2.0, this specific version remains a favorite for educators and hobbyists working with hardware like Arduino, mBot, and Ranger because it allows offline programming without the heavy system requirements of newer web-based versions. What is mBlock 3.4.12?
Return to the category and drag the block set digital pin (9) output as (HIGH) inside the loop. Change the pin number from 9 to 13 . Insert a wait (1) secs block from the Control category.
If the left sensor sees black (line), turn left. If the right sensor sees black, turn right. Else, go forward. mblock 3.4.12
: You can find structured PDF guides like How to Rock with Robots which are designed for mBlock 3 teaching environments.
This article dives deep into what mBlock 3.4.12 is, why it is still relevant years after its release, how to maximize its features, and where to legally find this legacy software.
| Feature | mBlock 3.4.12 ("Classic") | mBlock 5 (New Generation) | | :--- | :--- | :--- | | | Built on Scratch 2.0 | Built on Scratch 3.0 | | Programming Modes | Offers both "Scratch Mode" (Live) & "Arduino Mode" (Upload) | Focuses on "Upload Mode" for hardware, with a separate "Live Mode" for sprites | | Interface Design | A more traditional layout where sprites and devices are mixed | A cleaner, more intuitive interface where devices are clearly separated from sprites | | Device Support | Supports Arduino, mBot, Ranger, and Ultimate 2.0 | Supports all the above, plus newer devices like HaloCode, micro:bit, and an expanded list of Arduino boards | | Key Advantage | Simplicity and a direct, real-time connection for immediate feedback in "Scratch Mode" | Modern interface, cross-platform support (including a robust web version), and compatibility with newer hardware |

The adventure didn't stop there. The student wanted to teach mBot how to "see." Using the block-based environment of mBlock 3.4.12 , they added an ultrasonic sensor block to the script. : "If you see a wall, turn left!" The Result
At its core, . It is developed by Makeblock, a company known for its educational robotics kits like mBot and Codey Rocky. The genius of mBlock is its dual nature:
, a version of the software that acted as a bridge between the physical world and the digital one. The Spark of Life The student opened mBlock 3.4.12
Later versions of mBlock (4 and 5) often struggle with serial port connections or require complex firmware updates. Version 3.4.12 is brutally simple: you select the port, you click "Upload," and it works. It rarely crashes mid-upload, which is a blessing in a classroom of 30 students. Add one final wait (1) secs block at
As users snap graphical blocks together, the software generates real-time Arduino C++ code in a side panel, serving as a teaching tool for textual syntax.
In mBlock 5, the "Forever" loop has latency due to the software interpreting Python in the background. In 3.4.12 (Upload mode), this loop runs at the microcontroller’s clock speed (16MHz). The response is instant.
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.
