This is a ThinkerShield + Fidget Spinner + Light Gate Anemometer.
An anemometer is used to measure wind speed. Light gates send a signal every time the light beam is broken. Using a fidget spinner with halved ping-pong balls to catch the wind, the light gates can sense every time the spinner makes a rotation. The faster the spinner rotates, the faster the wind, and this can be measured with lights and buzzers on the ThinkerShield.
