I’ve been interested in microcontrollers for a long time. They’re small and cheap, they’re extremely customizable, and if you want to make a piece of electronics do something, they give you a balance between complete efficiency and flexibility. There are a lot of places where it’s likely possible to solve a problem using only passive components, but a microcontroller essentially lets you solve it by explaining what you want (i.e. programming it). Sounds just about perfect to me. I have a handful of projects I’m kicking around. Some are more curiosities, some have a little more substance to them. The [...]
