“Following the principle of the original Roulette, the movement of the LED simulates a ball whose speed gradually decreases until it stops.
Roulette is a casino game named after the French word meaning little wheel. In the game, players may choose to place bets on either a single number, various groupings of numbers, the colors red or black, whether the number is odd or even, or if the numbers are high (19–36) or low (1–18).
Most often you can find a project of a roulette game with 10 LEDs, so I decided to do with 37 LEDs as in the original whell.Following the principle of the original Roulette game, the movement of the LED simulates a ball whose speed gradually decreases until it stops at a randomly generated number. The construction is greatly simplified with the use of an Arduino microcontroller. Device is relativly simple to build and consist few components:
- Arduino Nano microcontroller
- 74HC595 shift register 5 pisces
- 37 Leds
- NPN transistor
- 2 Resistors
