This kit configures 10 LEDs in a circle. When the button is pressed, each LED will light up in sequence. The flow speed starts fast, then gradually slows down until it stops on a specific LED. Press again to restart. If the final illuminated LED matches the player's prediction, it indicates a "win." Assign 10 different items or actions to the numbers 1-10. When the LED stops, the corresponding number indicates the selected item or action. It can be used as a number guessing game, electronic dice, or random selection device.
