Arduino IO Expansion

So an interesting thing happened last night......

I was watching something on Youtube and someone mentioned ChatGPT, which reminded me how I joke with a friend that his code sometimes looks like ChatGPT wrote it.

So then It dawned on me that I should peg ChatGPT about adding the I2C IO to Arduino Connector. I'd never used ChatGPT before but I figured why not......

A couple hours later I have  the MCP23017s all working as inputs/outputs within Arduino Connector......

I was pretty blown away by how that turned out.
