, this version represents a key milestone for the legacy mBlock 3 software—a visual programming environment based on Scratch 2.0 Pinoo Robotics
This version excels at two workflows:
: If your robot isn't connecting, use the "Connect -> Install Arduino Driver" menu option. mblock 3.4.12
mBlock 3.4.12 is often recommended over newer versions when working with specific legacy hardware or classroom sets that require 2.4GHz wireless dongles, as some of these connection methods are limited in later versions. Compatibility Recommended Use Case Beginner robotics and classroom lessons. mBot Ranger Advanced mobility projects and multi-sensor tasks. Ultimate 2.0 Complex mechanical builds and engineering. Arduino Boards Standard Uno, Mega 2560, and Leonardo boards. mBlock 3 vs. mBlock 5: Why Use Version 3.4.12? , this version represents a key milestone for
For the tinkerer with an old Arduino, the teacher with a budget-conscious IT department, or the parent wanting to introduce their child to actual engineering (not just screen-based games), finding a copy of mBlock 3.4.12 is like finding a classic tool in a shed—it doesn’t need an update; it just needs to work. mBlock 3 vs
: For "Online Mode" (running code directly by clicking the green flag), you must first go to Connect > Upgrade Firmware . This clears pre-loaded programs and prepares the board for live interaction. 3. Programming Modes mBlock 3 supports two primary ways of running your code: mBlock - One-Stop Coding Platform for Teaching and Learning
| Feature | Description | |---------|-------------| | | Based on Scratch 2.0 (not 3.0) – familiar layout, no browser needed. | | Arduino mode | Switch from "Stage" to "Arduino" mode to program boards directly. | | Code viewer | See generated C++ code for each block – excellent for transition to text coding. | | Board support | Arduino Uno, Mega 2560, Nano, Leonardo, and Makeblock Orion (custom Mega). | | Sensor support | Built-in drivers for ultrasonic, temperature, PIR, joystick, IR receiver, etc. | | Firmware uploader | One-click to flash standard firmware to Arduino for live stage interaction. |
