How it works:
Drone motor +
propeller
Servo motor
Battery
Micro:Bit (“brain”)
Bubble:bit is controlled by a
micro:bit which runs a small
program.
When you press button B, the
hand will dip the ring in soapy
water and the propeller will
start. A film of soap will form
and when the air is blown
through, soap bubbles will
form!
