CircuitPython School - Adding STEMMA QT/Qwiic to an Arduino RP2040 + Using a Temperature Sensor

Learn to add a STEMMA-QT/Qwiic connection using a breadboard and a cable that costs less than a dollar. We use an Arduino Nano RP2040 Connect, but the technique should work on other boards, as well, as long as the correct SDA and SCL pins are used. We also use the Adafruit MCP9808 temperature sensor, and we learn to format numbers to a specified number of decimals, or no decimals at all. Part of Prof. John Gallaugher's Physical Computing Course using CircuitPython.

Great tutorial. Would love to see some help with directing how to steer boards with both GPIO and qt connections. I’m having a heck of a time getting an uno R4 to find my daisy sensors in example scripts except with single sensor examples.
