These examples have been run in the past using the AVR boards 1.8.2 which I had to use instead of 1.8.3

The current version of the AVR boards is 1.8.5 so I don't think it is worth continuing with these codes.

I will leave these in place in case anyone wants to investigate further.

Some do seem to be working. The Aruino166 ones are more difficult.

These codes do now work with Arduino IDE 1.8.19 and 2.3.2
