ES-16 10-LED Roulette (wheel of fortune) with slowdown function (DC 9V)
10 LEDs arranged in a circle & numbered from 1 thru 10. When the button switch is depressed, a lighted "ball" spins rapidly. When released, the ball slows down & stops on one number. The circuit has built-in auto power off function which turns off the kit when it's left idle for a few second. (helps to save battery power)
