3.4.12 _top_: Mblock

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

is one of the final stable revisions of the mBlock 3 series, a visual programming environment based on Scratch 2.0 . While the developer, Makeblock , has since shifted focus to mBlock 5 (based on Scratch 3.0), version 3.4.12 remains a popular choice for legacy projects and specific hardware kits like Pinoo Robotics . Core Features

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

It provides a very direct experience for updating firmware and managing serial port connections without the need for additional bridge software like mLink. mblock 3.4.12

: To test or calibrate a line follower module, you should place the sensors 1–2 cm above a white sheet of paper to see if the corresponding LEDs light up. Key Resources for mBlock 3.4.12

While mBlock 5 offers cloud capabilities and more advanced AI features, remains favored for specific scenarios:

mBlock 3.4.12: The Ultimate Guide to the Classic STEM Education Software Connect your hardware to the computer's USB port

The built-in blocks for sensors (ultrasonic, line-follower, temperature, potentiometer) and actuators (servos, DC motors, RGB LEDs) are comprehensive. You can control an LED on pin 13 with the same ease as moving a cat sprite.

During or after installation, navigate to the "Connect" menu and select "Install Arduino Driver" (CH340/CH341 drivers) to allow your PC to recognize USB connections to the boards.

Run the driver installation tool from the "Connect" menu again. Select the Serial Port is one of the

mBlock 3.4.12 remains one of the most reliable, stable, and widely used legacy versions of the mBlock educational software ecosystem. Developed by Makeblock, this platform bridges the gap between visual block-based coding and text-based open-source hardware programming. Built on the foundation of Scratch 2.0, mBlock 3.4.12 offers a unique environment where students can see their graphical code instantly translate into C++ (Arduino compilation code).

: Specifically optimized for Makeblock’s signature robots like the mBot and Ranger, but also supports standard Arduino Uno, Mega, and Leonardo boards.
