Roulette composed of an electronic control board and an LED panel, all realized with integrated HCMOS (74HCxxx). A clock signal properly emulates the real movement of the roulette wheel that quickly aside to go away-via decreasing to a stop. To play the sound of the ball flowing is always used the clock signal, which is amplified by a final small 2x3-watt class D (not included - see related products).
To operate simply connect any power supply 5 VDC and press and hold the button; They will turn on the LEDs in sequence and in a clockwise direction at a speed of approximately one complete revolution per second.
When you release the button, the "rotation" of the LEDs will continue for about eight or nine full turns at speeds that will gradually decrease until it stops completely, in the case of an LED.

This project comes in kit. Some components have to be soldered to the included PCB.
