makeEspArduino VS ArduinoCore-avr

Some people regard the Arduino-IDE as clunky (it is), but I side-step that by compiling with makefiles.

Gotta pick some project that matters to you and do it. Putting Python code into production with multi-person teams is outright maddening, but for the individual who wants to put their skills on wheels, Python is a great place to start.

Another fun thing to try is

https://www.arduino.cc/

I got started with that buying an Arduino and a breadboard and a handful of 74xx logic chips and I started writing Arduino programs that would generate inputs to the 74xx chips and verify the expected outputs and thus taught myself C coding for the Arduino and how to make circuits with discrete logic at the same time.

Check out existing implementations like Arduino: https://github.com/arduino/ArduinoCore-avr/blob/master/libraries/SPI/src/SPI.h

you can always just use an ide but i use this one on my old chrome book https://www.arduino.cc/

You'll also need the avr C library and the Arduino library, and possibly a Makefile or similar to corral the compilation process

Ya for $25 you either want 4-5 clones, or support the official Italian Arduino makers as thanks for making the entire ecosystem possible by buying one of their own boards from https://www.arduino.cc/

It depends what exactly is she into. For electronics you can check out arduino. They sell full kits with everything you need - some components like leds, breadboard so you can create circuits without soldering and a small 8bit computer to control everything with. AFAIK they also sell kits specifically for education starting with middle school.

They are in via Arduino. ;-)
