MicroBlocks is a visual programming IDE for 32-bit microcontrollers
Most electronics education platforms have good documentation in English, but it may be more difficult to find details instructions in other languages. The good news is that MicroBlocks also offers a few tutorials in German, Chinese, Dutch, Spanish, Catalan, and Turkish. The source code is available on Bitbucket which includes the Arduino/PlatformIO firmware for each supported board and the IDE written in GP Blocks.
Another reason MicroBlocks project caught my eyes is that I had seen several people share something about “MicroBlock” (note: no “s”) on Facebook last week. But it happens to be a visual programming IDE for the KidBright32 education board in Thailand, and MicroBlocks and MicroBlock are completely separate open-source projects albeit with a similar use case… You’ll find more details about MicroBlocks on their website.
