This is Mini LED roulette game circuit using Digital IC, so simple and easy to builds, using IC to drive LED1-LED10, IC is oscillator, IC Jan 08, · A spinning led roulette wheel that uses a and a IC various resistors, and two capacitors. These are basic, yet fun, electronics kit from radio shac. May 19, · I'm having problems with my circuit that I've designed and I feel as if I'm just a few meters from the finishing line here. I have been trying to design an Electronic Roulette Wheel with the use of timers, Decade Counters and LED's.
10 LED roulette circuits using TC4011-LM4017
Yeah, the can drive a LED, but don't expect it to also be able to maintain a valid logic level if you're passing more than a couple of mA to the LED see the specs for more details. Finally strap the battery connector to a 9 volt PP3 type battery. Initially you will find that out of the 10 odd LEDs only one is lit up. Rleo, May 16, As the LEDs start blinking we can adjust the speed of the blinking LEDs by setting the value of resistance through a potentiometer connected in the circuit because changing the value of resistance will change the oscillation frequency of the timer IC, hence the rate of clock pulse. Watch the ball as it settles into a slot, which determines which number is the winner.
As same, here we are making a wheel or circle shaped led blinker, using timer IC placed in Astable mode , and IC which is decade counter IC and small needful components. This IC is used to generate output in a sequence manner like it start from zero and goes up to It shifts it output from one pin to another by applying clock pulse at PIN Here this clock pulse is generated by Timer IC in astable mode.
Used to cascade another IC to makes it count upto 20, it is divide by 10 output PIN, we can count how much we want just by cascading the ICs through this pin and every IC will generate 10 outputs.
In operating condition this pin will remain at Low, beacause if this pin is High, will stop the pulse generation means it will be in freeze mode. Now we will connect the LEDs in a roulette design circle shape , as we used 8 LEDs which are connected by the output pins of the IC according to the sequence of output, start from zero and goes up to 10 but we are using only 8 output pins as the number of LEDs are 8 and its gets the clock pulse or pulse input from the timer IC in Astable mode.
As the LEDs start blinking we can adjust the speed of the blinking LEDs by setting the value of resistance through a potentiometer connected in the circuit because changing the value of resistance will change the oscillation frequency of the timer IC, hence the rate of clock pulse.

I'm hoping that you can notice something rather obvious that I've missed, maybe a silly connection somewhere? I know it's rather difficult to just look at a schematic and find out whats wrong with it and it's a lot to as but I'm really stuck and I feel so close to finishing my project. Stuart, May 15, Jan 5, Messages: Yes, you are missing something.
The threshold and trigger pins of the must be connected to the top of C3. BobK, May 15, I'm assuming you mean like this? It's still not working, back to the old drawing board for me. Are you getting pulses out of the ? Also, you have a switch for the power to the When simulating is that switch on?
I believe so yes, I just connected two LED's in series to the 's Output pin and they are flashing so I'm assuming that's me getting pulses from the ? I can't read the schematic well enough to determine if the part is working.
Jan 22, Messages: I'm not good interpreting datasheet. What the part number of your and gate? It seems its output capable of driving LED to lit. Rleo, May 16, I'm fairly sure it can but I'm starting to doubt myself. As for my AND gate I do not know the part number as my electronic workbench does not state what it is. All it says is "Value: Unfortunately I'll need to do that later on today because I'm currently away from home Stu. Stuart, May 16, Jan 21, Messages: Mid way between Beijing and the Ronne Ice Shelf.
Roulette is one of the easiest casino games to play and is also one of the oldest games available in casinos around the world. So how do roulette payouts and odds work?
Roulette has a consistent house edge and straightforward odds. One of the main advantages of playing roulette is you play fewer spins per hour than you play hands per hour at the blackjack table, baccarat table, or at the video poker machine. When you combine this with the simple game-play where all of the bets have the same edge, roulette is a good choice for many casino players. Take a look at the odds, payouts, and house edge that are offered when playing on the American, European, or French roulette wheels.
Be sure to look at the section on how the house edge works to get familiar with why American roulette has a higher edge than European or French. This is based on the US wheel. It is the most popular type of roulette played at most of the online casinos, as the house edge and odds of winning make it the best choice for avid players.
The only difference between European roulette and French roulette is that in French roulette if you bet on high, low, red, black, odd, or even and the ball lands on zero, you only lose half your bet. So, the house edge on these bets is half of what it is on a European wheel. Experienced gamblers avoid the US wheel, in favor of the European version —or even better, the French Roulette game, which has the best odds of all roulette payouts.
There are two types of bets that a player can place —inside and outside bets. These are relative to where you would actually place your chips on the table. Learning the type of bet and where to place the bet will help you know what your possible roulette payout will be.
