After working in AI for a big chunk of my career, I have switched gears in retirement and am having a great time learning to program small controllers like Arduinos. It's like going back in time - minimal OS, simple tools and direct access to the hardware. Just for the heck of it, I am building a simple robot from scratch right now and its been great getting back to the basics.
