My LED game for assignment 3 has the objective of getting all 3 lights to be on at the same time. Although it sounds simple the game has some nuances of turning ON certain LEDs turns OFF other ones.
My instrument for assignment 5 uses tilting the microbit to change the tone. Pressing the b button speeds up the tempo and pressing the A button resets the tempo. https://makecode.microbit.org/_PzkL1f
