A very simple 10 LED roulette wheel circuit is shown here. pressing the button starts the LEDs in a rotational motion (sequencing) at full swing initially, and gradually slows down, until it stops to a particular, randomly selected LED.
The randomness of the selection depends upon the time for which the push remains switched ON by the finger. Even a difference of 0.1 second is able to change the position of the final LED position, making the roulette application highly foolproof.10 LED

hi, at the 100k resistor why is there a wire connected at the middle of it? thanks in advance
that is the center pin of the preset joined with one of the outer pins.
Hi,
I would love to understand how exactly the NE555 and decade counter CD4017 with all the other components work in this circuit. Thanks you in advace!
Hi, for that you will have to learn how the 4017 pinouts work:

Could you please make a circuit on car tail and break light controller. Where the tail light (led strip should glow while the car is running when brake applied it should be more brighter.
It is already posted in the this website, please use the search box to find it!
Pls i need a circuit of power optimizer or power booster to use pressing iron with small tiger generator, or how can i create the circuit
you will have to provide the complete specification and working details of the project, only then I would be able to suggest…
can you pls list down the values of the needed components like the resistors and capacitors because i cant understand clearly, and can i use different values than the given in the photo?
please click the diagram to enlarge and you will be able see the part numbers clearly
Where should I supply – voltage in the circuit?
(+) at the top most rail or line…(-) at the lower most line or rail
How much supply voltage should be given to it and how can I increase the LED
you can use any supply between 6 and 15V….since there are 10 outputs from the IC 4017 therefore only 10 LEds can be driven….
