Electronic Roulette Wheel Circuit Schematic

The circuit uses a 555 timer and a 4017 counter/decoder to flash 10 LEDs in a Roulette style sequence when the "Spin" switch is pressed. When the the button is released, the circuit slows the LED's flashing until only 1 LED remain lit, which is obviously the winning (or losing) LED :)

The circuit uses about 20 electronic components, 10 of which are LEDs, 2 ICs (555 timer and a 4017). This schematic looks like it's very easy to build into a circuit... enjoy!
