Go to the Boards menu and select your hardware (e.g., mBot, Arduino Uno).

| Problem | Likely Fix | |---------|-------------| | "Serial port not found" | Install CH340 driver (for clone boards). On Windows, check Device Manager. | | Upload fails (stuck at 0%) | Press reset button on Arduino just before upload. Lower baud rate in Edit > Serial Port to 57600. | | Stage mode not reading sensor | Re-upload firmware: Connect > Upgrade Firmware . | | Blocks missing for a sensor | Use "Arduino" category blocks (digital/analog read/write) for custom sensors. | | mBlock crashes on Windows 10 | Run as Administrator, or set compatibility to Windows 7. | mblock 3.4.12

: Ability to add community-made drivers for third-party sensors.

: Built on the intuitive Scratch 2.0 framework, making it accessible for absolute beginners. To demonstrate the workflow of mBlock 3

This occurs if the software tries to write to a port that is busy or misconfigured.

: Real-time translation from blocks to code. Select Arduino Uno from the dropdown list

While newer, web-based versions like mBlock 5 exist, version 3.4.12 is highly favored by educators and hobbyists who require a stable, offline desktop environment that interacts seamlessly with older hardware configurations. Why Choose mBlock Version 3.4.12?
