Are those really tutorials for AVR chips or tutorials for the Arduino ecosystem? Arduino is not limited to AVR, there is no need to put up with the limitations of those aging chips, unless you are accessing hardware registers directly you can probably run the same software on a STM32 or SAM D board.

I was specifically thinking of the ATtiny85 when I made my comment. A beginner's first electronics project is often blinking an LED on and off. When I'm teaching a room full of kids electronics for the first time, the simplicity and low-cost nature of the ATtiny chips are hard to beat. I get it, ARM chips are great for real projects, but there is still a place for 8-bit AVR.

  I've literally just received a delivery of through-hole ATTiny85s and a programmer, so I can dead-bug an I2C interface onto an analogue sensor. I have no idea where I'd start looking for an ARM in anything like the same form factor.

    There are through-hole ARM ICs, e.g. see https://hackaday.com/2013/05/29/programming-a-through-hole-arm-microcontroller/ https://hackaday.com/2013/05/29/programming-a-through-hole-a.... For example: https://www.digikey.com/en/products/detail/nxp-usa-inc/LPC810M021FN8129/12102361 https://www.digikey.com/en/products/detail/nxp-usa-inc/LPC81....

      There were through-hole ARM ICs, but they are no longer in production.

        I've just had a quick look, and there are some very small BGA-packaged STM32 chips about. With a competent PCB fab you might be able to knock together a board with 8 jumper pins that wouldn't be much bigger in total than a SOIP attiny, but that's another job plus whatever peripheral components need to be added. Might be a fun design job, though. https://www.mouser.co.uk/ProductDetail/STMicroelectronics/STM32G030J6M6?qs=uwxL4vQweFMe%2Fiu4dY6izA%3D%3D https://www.mouser.co.uk/ProductDetail/STMicroelectronics/ST... looks like it might be a lot of fun, but it's got a 6 month lead time on it.
