Raspberry Pi Pico & STEMMA QT / Qwiic + Using a Temperature Sensor & Formatting Numbers

In this lesson we learn to attach a STEMMA-QT / Qwiic connector to a board that doesn't have one. We'll use a Raspberry Pi Pico W, but the technique demonstrated here can be used with most boards that don't have a STEMMA-QT port. I'll also demonstrate the use of an Adafruit Cowbell Photo board to add STEMMA-QT / Qwiic to a Pico, we'll work with an Adafruit MCP9808 temperature sensor, and we'll learn to use String Format Specifiers and F-Strings to format numbers to a specific number of decimal places.

Glad you like it! I’m going to be upgrading the series over the coming week using PyCharm and CircUp plus the latest releases. Stay tuned. And thanks for your motivating comments. Hack on!

Excellent! Thank you.

You are most welcome!

thanks! which side up/down do you plug the Stemma QT in? It seems to fit both ways...

Hi. Look at the bottom of the JST jack at the end of the cable. You should see there are metal bits. Those should touch the corresponding in the receiver jack. Those are usually on the bottom-side of the board you're plugging into. If you flip it over you can force it in, but that's definitely not what you want to do. You also know you're the right way because most (but not all) breakout boards have a power light to say "I'm connected properly".
