Getting Started with MicroBlocks

MicroBlocks is a new programming language inspired by Scratch that runs right inside micro-controller boards such
as the micro:bit, the NodeMCU and many Arduino boards. The MicroBlocks system allows for dynamic, parallel
and interactive programming, just like in Scratch, but with the twist of letting your projects run autonomously inside
the board without being tethered to a computer. Thus, MicroBlocks provides the immediacy and liveness of tethered
blocks programming, while supporting real-world applications that require precision timing, autonomous operation,
or physically embedding the processor into projects. For example, one might write a program to record acceleration
data, then embed the microcontroller and a small battery in a model rocket to explore G-forces at launch time.

In other words, MicroBlocks lets you program your boards exactly like you would in Snap4Arduino, S4A or the
Arduino extension for Scratch, and when you are happy with your program you can just unplug the board from your
computer and everything will keep running as if by magic!

With MicroBlocks, you can build your own “real world” digital instruments, interactive jewelry, electronic games and
measuring devices, all by using blocks.

You can download MicroBlocks from

here
