EdScratch vs mBlock

EdScratch is a free, browser-based block programming environment for Edison robots. Its vertical drag-and-drop language is based on Scratch and is described as suitable for students aged 10 and up, including those new to coding. It has versions for Edison V2 and V3, with blocks for driving, LEDs, sound, data, events, control, sensing, operators, and comments. Programs can control robot inputs, manipulate data, and use variables. A built-in bug box checks programs and displays warnings. Users can save programs to a computer and load saved EdScratch files into the online app. Edison V3 can receive programs by USB from a computer or by optical flashing from an iPad; V1 and V2 use the EdComm cable. A free lesson set offers 98 student activity options across six units, along with a teacher’s guide. EdScratch runs online on the web, Windows, macOS, iPadOS, and Android, and requires an internet connection. The interface is in English, while lesson resources are available in multiple languages.

mBlock 5 is a free coding platform for robotics, STEM, and coding learning. It supports block-based coding and Python, with a one-click switch between the two. Users can create games and animations, then program Makeblock robots and other open-resource hardware. The platform includes AI and IoT features, with integrations described for Microsoft Cognitive Services and Google deep learning. Supported devices listed include CyberPi, mBot Neo/mBot2, mBot, mBot Ranger, Ultimate 2.0, mBot Mega, mTiny, Codey Rocky, and xLight. The Extension Builder allows third parties to develop device and sprite extensions. mBlock is available on Android, iOS, Linux, macOS, web, and Windows. The web version supports direct Bluetooth or serial connections, but not the Bluetooth dongle. The mBlock Python editor programs devices only for CyberPi, and its Upload mode uses MicroPython rather than third-party Python 3 libraries. The Extension Builder works only in Google Chrome.
