Mblock 3.4.12 ((full)) Jun 2026

Should this feature focus on capabilities or Offline Hardware control?

The interface of mBlock 3.4.12 is strategically divided into four primary zones designed to streamline the workflow from logic design to hardware deployment. 1. Stage and Sprite Management

If you are setting up a classroom lab or working on a specific hardware project, let me know: What are your computers running? What specific robot kit or Arduino board are you using? What type of project are you trying to build?

Start your script with an mBot Program or Arduino Program cap block. Right-click the top block and select Upload to Arduino to run the code autonomously without a computer. 4. Essential Block Categories mblock 3.4.12

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.

Unlike newer browser-based tools, 3.4.12 runs entirely on your desktop, requiring no internet connection once installed.

To help you optimize your classroom or project setup, could you share what you are planning to run this on, and what specific robot or microcontroller board you intend to program? Share public link Should this feature focus on capabilities or Offline

Users drag blocks into the script area. For example, dragging a "when green flag clicked" block followed by a "set led on board onboard to red" block creates an immediate visual instruction. This mode interacts with the hardware in real-time via a USB cable or Bluetooth 2.4G serial module. Arduino Upload Mode

: It is highly optimized for older PCs and specific educational kits that may not be fully compatible with the newer web-based architecture of mBlock 5.

Users drag blocks into this central canvas to construct their programs. Logic flows vertically from top to bottom, utilizing standard programming constructs like loops ( forever , repeat ) and conditionals ( if-then-else ). 4. Arduino Code View Stage and Sprite Management If you are setting
