circuitpython
CircuitPython is Adafruit's branch of MicroPython designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads.
With CircuitPython you can write clean and simple Python code to control hardware instead of having to use complex low-level languages like C or C++ (what Arduino uses for programming). It's great for beginners!
Visit the CircuitPython section of our Learn Guide to learn more about using this awesome coding language and visit our #circuitpython channel on Discord to start chatting with the CircuitPython community
