@dale and @byron Thank you both for the thoughtful responses. Because of bad weather and a dozen other things, I'm just getting back to this now. I ...

@byron thanks, both suggestions make a heck of a lot of sense. I like the malloc() call and flashing LED idea in particular. The Serial.print(s) mig...

It certainly has a lot of enhancements and new features. I vote yes to a video! - Paul VE1DX

@wolfgangw I can't take the credit. They are kits. The only challenge was the soldering of the SMDs with an iron. There are better ways to solder SMD...

They all do the same thing. The SMD/SMT version was a challenge in soldering with an iron, but it works well. They "crammed" all the stuff shown in t...

@codecage I dunno, Steve. Paypal is better than giving your CC number to some faceless company you rarely/never heard of. I think PayPal has a prett...

@jonaskell That looks like the old mess we'd get on RS-232C interfaces if we had the number of data bits wrong, the parity bit set incorrectly, etc. ...

This thing works fine. I would not have expected otherwise, and I really don't know if it is "necessary" these days. I can't easily find ATmega328P ...

Indeed it is. I like the idea of SMD resistors to fix little "Oops" oversights after the fact. Looks like you did some fancy footwork to get that in...

@codecage Sure is, Steve. Being a real "robot engineer" is beyond me (unless you count putting together the Elegoo kit.) However, Arduino and Pi ha...

More or less. I didn't analyze what every component does, but I have a general idea. The point of getting this kit was because it was a novelty. I'...
