How to turn Arduino CLI compile checks into a small pipeline: compile on pull requests, save hex artifacts, optionally lint, and keep flashing boards as a local or tagged-release step, not something GitHub-hosted runners can do without hardware.
Duplicate an official Blink example in Arduino App Lab, read main.py and sketch.ino, change the Bridge call, Run, and know how to get back if IDE 2 overwrote the microcontroller.
How to use MicroPython's Read-Eval-Print Loop in Arduino Lab: live lines, paste mode, Stop, soft reset, and why REPL experiments are not the same as a main.py you can reboot.
A practical comparison of Arduino C++ and MicroPython on Arduino boards: compiled vs interpreted, speed, memory, how fast you can try an idea, the REPL, libraries, debugging, hardware access, and which one is easier when you are new.
How to put MicroPython firmware on a supported Arduino board with Arduino's MicroPython Installer, which boards are on the list, and how to get Arduino C++ back by uploading a sketch.
What Arduino Lab for MicroPython is, how it differs from Arduino IDE 2, how to put MicroPython firmware on a supported board, how the REPL and file transfer work, and how to get back to Arduino C++ when you want the sketch workflow again.
