Prototype Test for Pull Request to ask about best way to handle Wire.…

[davidorser]

I was getting errors with the default 1.8.19 IDE when trying to compile this example. I looked up wire.begin() on Arduino's documentation page and it returns void (not an int/bool.)

This change would let it compile, but is there a better way to do this? I imagine I'm missing something though. I skimmed the Arduino wire.* methods and didn't see anything that would indicate success in starting the interface.

If this is reasonable, I will expand the final pull request to include all 4 examples.

Thanks for this PR! I ran into the same problem when debugging #7 on a ReadBoard Plus. Some platforms (eg. ESP32) make Wire.begin() return an error code, but that's not true across all platforms, so your solution is the best way to do it for all platforms. Was going to do this myself, but saw this so I'll merge it in after changing the other examples to match 😉
