Use Connect > Reset Default Program to restore the robot's original factory settings (like remote control mode). Unlock Creativity : Easy Arduino Programming with mBlock!
To implement this in mBlock 3.4.12, the extension definition would look like this: javascript
Any variable tagged as "Cloud-Hardware" automatically generates Serial.print() commands in the background.
Users can see the corresponding Arduino C code generated by their blocks, aiding the transition from visual to text-based coding. Why Choose mBlock 3.4.12 Over Newer Versions? mblock 3.4.12
The version number "3.4.12" typically follows a semantic versioning system, which is common in software development. This system is usually represented as MAJOR.MINOR.PATCH:
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.
In mBlock 3.4.12, variables created in "Scratch mode" often don't translate directly to "Arduino mode" without manual re-coding. Users have to choose between seeing real-time data on the stage or running the code independently on the hardware. Use Connect > Reset Default Program to restore
: The flagship entry-level educational robot kit.
If you are looking to set up your environment and get a robot moving, the process is incredibly streamlined:
This version was a part of the 3.x lifecycle. While Makeblock never made the source code for 3.4.12 publicly available, the community has pieced together its context. Users can see the corresponding Arduino C code
You cannot easily add new sensors. If a component isn't in the default library, you must manually edit the arduino folder inside the program files (a nightmare for teachers).
If you are using a cloned Arduino board with a CH340 chip, Windows may block the driver. Restart Windows with "Disable Driver Signature Enforcement" (Shift + Restart -> Troubleshoot -> Advanced Options -> Startup Settings) before connecting your board.
As mentioned, mBlock 3 is no longer supported by Makeblock. Therefore, downloading version 3.4.12 specifically from official sources is no longer possible.
mBlock 3.4.12 bridges the gap between absolute beginners and text-based hardware programming. By maintaining a clean Scratch 2.0 interface alongside real-time C++ generation, it serves as a powerful tool for schools and makers who value consistency, offline stability, and reliable control over Arduino-based ecosystems.
