Nice, Thanks

Wokwi simulation of this code (with two connected I2C devices):
https://wokwi.com/projects/328854546483774035
no idea if it's a new version thing or because I'm using a pi pico instead of esp32, but I had to use an extra argument for the I2C
added the 0 after I2C(
i2c = machine.I2C(0, scl=machine.Pin(9), sda=machine.Pin(8))

Very valuable means to show the first steps in setting up and accessing i2C resources. Other "1st steps" tutorials assumed Pin objects and abstractions that I hadn't learned yet. This gave the starter everything needed.
