Comprehensive Power Management for the Raspberry Pi
This is how I go about writing #code for #AVR #microcontrollers. (For subscribers).

I think the appeal is that the size corresponds with the price tag. Though not always the case, smaller stuff == cheaper.
My first set was an Elegoo Arduino Uno Super Starter Kit I got second hand for 25€. A mega good deal considering that the real deal costs, just the board alone, 20€. Some of the parts in the kit sucked though.
Then I got the esp32c3 super mini for 1,07€. If anyone wants to start out with microcontrollers, it's the board I recommend. The Arduino IDE supports it and it works out of the box. I think it's 60 cents more if you want the pins pre-soldered.
I don't recommend atmega stuff! For what they are, they're not as cheap as the alternatives. For example, an attiny85 costs between 2-3,5€. The stm8s001 costs less than 1€ a piece and has 2x the clock speed, 2x the RAM and 2 16-bit timers, which is 2 more than the ATTINY, which has none.
Made a little morse serial transmitter with my new #arduino 😄
It decodes button presses in real time and transmits the character with UART. The 'words per minute' is currently hardcoded, so on-offs need to be somewhat fast (for me anyways).
The code is here, written in AVR C. Reviews welcome!

looks like this gizmo is more than just a glorified rotary encoder, can't wait for the campaign to start 😻
