Please find below the various piece of code that together control my RGB light to loop in Rainbow.
Every two seconds, it change from one colour to another based on the value of the second.
So it compute 30 differents RGB value in a "circle", all with the same Saturation and Brightness both forced to 1.0
The transition from one colour to another is done in one seconds.

The name of my Tradfri RGB light bulb is "light.couleur"

I needed a way to type my computer from my phone, acting as a keyboard. But I cannot add software to my computer, so I needed to be a USB-HID device. I asked Gemini for help, and he produced this code, first for US EN keyboard, but then I addapted it for Belgian French.

For the Belgian French keyboard, I went to Neradoc repo, but Î could only find French keyboard: https://github.com/Neradoc/Circuitpython_Keyboard_Layouts

So Î went to his page: https://www.neradoc.me/layouts/ Gave it the Belgian French keyboar page: https://kbdlayout.info/kbdbe And it generated for me the needed Python file

STATUS

CircuitPython does not support USB Host yet, but the basis API and partial implementation.

adafruit/circuitpython#6527

The idea is for CircuitPython to rely on TinyUSB, the same way it does for USB Client activities.

Some hardware that run CircuitPython are designed with USB Host in mind such as:

# This file should be saved as code.py
# At MagTag startup (or at wakeup time), keep one one of the 4 button pressed.
# The MagTag will switch to the program you choose and remember that decision at each wakeup.
# The trick is to have for each button one CircuitPython program to import.
# You can customise the app_to_start list, here is the current setting:
# no button => magtag_weather
# 1 (D15) => magtag_showtimes
# 2 (D14) => magtag_tree
