Today our young coders stepped into the world of AI + machine learning using the BBC micro:bit. They:
✨ Trained their very own machine learning model using real data from the micro:bit’s movement sensor, and recorded data samples of exercising vs not exercising
✨ Watched how the computer spotted patterns in their movements
✨ Used MakeCode to turn that model into a working activity timer that automatically detects when they’re moving and when they’re resting, using the sensors and lights in the micro:bit
✨ Tested, tweaked, and improved their models just like real AI engineers to make the more accurate, and detect different types of exercise
And for those with 10 minutes to spare, they;
⛄ Built a festive “Whack-a-Snowman” game in MakeCode Arcade.
A fantastic session to round off the term.
