    Thumbs up Just a tiny correction.

    "adding I/O's with the MCP23008 or 20016 is a very easy and neat solution"

    Melanie is referring to the MCP23016, in case anyone is trying to find a 20016.

    I agree, I'm in love with the MCP23008/16 chip (8 and 16 I/O pins). It's an awesome way to increase I/O pins on older chips like the 16F628 (a good strong and proven workhorse if you ask me).

    The 16F877 is better, but at a cost. If you don't need more I/O pins AND extra memory, then it's overkill in a lot of applications.

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
