I'm trying to learn how to use I2C so that was the route I took.
So far I've got the sensor data to display on the serial monitor. The sensor is connected to A4,5.
That's analog. (?) I'm pretty sure it is Hence the A4, A5.
those pins are magically tied to I2C on your UNO (A4 is SDA, A5 is SCL).
so what is your question, then?
