Not really, not if the tooling is half decent. And for stuff like the Arduino it's fairly good, even for a beginner with a wee bit of programming knowledge.

I used to be pretty fluent in 6502 back in the early 80's, it's a long forgotten skill in my brain. I bought an Arduino kit back in 2010 and had a bunch of flashing LEDs working in about half an hour. And I'm not that clever. It's all about the tools.
