It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips.

But times have changed. Digikey lists over 16000 different line items under a ‘microcontroller’ search. Which one should a hobbyist with no particular prior experience choose? Continue Reading…
