## About micro:bit's MicroPython
micro:bit's MicroPython is developed by [Damien George](https://github.com/dpgeorge), after the initial effort to [bring Python onto micro:bit](https://ntoll.org/article/story-micropython-on-microbit/) failed. Theer are two other major variants: [MicroPython](https://micropython.org/) and Adafruit's [CircuitPython](https://circuitpython.org/).
micro:bit's MicroPython is developed by [Damien George](https://github.com/dpgeorge), after the initial effort to [bring Python onto micro:bit](https://ntoll.org/article/story-micropython-on-microbit/) failed. Damien George developed the original [MicroPython](https://micropython.org/) in 2013, which also has a derived version: Adafruit's [CircuitPython](https://circuitpython.org/).
All MicroPython variants are based on standard Python or CPython `3.4`, while the other MicroPython versions incorporated a few features from newer Python. Unlike the ["fake" Python in the MakeCode editor](https://makecode.com/python), these are actual Python interpreters with full language syntax support, all basic built-ins along with a few special modules for the microcontrollers. On the other hand, most of the built-in modules are not available due to the hardware limitation. Not that we'll need them a lot for STEM education anyway.

For both micro:bit V1/V2 you don't really need a resistor to protect the LED. The voltage and current from any pins (except the 3V pin) are low enough.
Note: for both micro:bit V1/V2 you don't really need a resistor to protect the LED. The voltage and current from any pins (except the 3V pin) are low enough to cause real harms.
