10 LED Simple Roulette Wheel

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

How much supply voltage should be given to it and how can I increase the LED
Swagatam said…
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....

Where should I supply - voltage in the circuit?
Swagatam said…
(+) at the top most rail or line...(-) at the lower most line or rail
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?
Swagatam said…
please click the diagram to enlarge and you will be able see the part numbers clearly

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
Swag said…
you will have to provide the complete specification and working details of the project, only then I would be able to suggest...
