4017 roulette

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.

555 Timer & 4017 LED Circuit

This IC is used to generate output in a sequence manner like it start from zero and goes up to Watch the ball as it settles into a slot, which determines which number is the winner. On pressing the Switch S1, the reservoir capacitor C1 almost instantly gets charged, also at this point of time a constant stable clock is fed to the IC and the LEDs at its outputs light up in a cyclic manner producing a revolving effect. Figure 2 The components layout of this projects. I'm busy right now with other projects. Jan 5, Messages:

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. Hey bro I think you forgot to connect IC pin no 16 to Power supply I connected it in mine then only it worked. Yes the circuit diagram is missing the 16th pin.

And hence its assumed to be connected to Vcc Thanks pushpak for the info. Skip to main content. By Pankaj Khatri 2 Comments.

Read on the easy instructions to build your own simple electronic game. Roulette games can be commonly seen in casinos and clubs. It is a playing device having a large conical shaped wheel with numbers or scores printed on its pockets in a special random manner. It is normally used for betting and wining cash amounts.

The wheel is rotated manually and few balls are thrown into its pockets which shuffles its position as the wheel rotates and eventually settles down into one of the randomly selected pockets with either a winning or a losing number.

The electronic version of such a roulette game is presented here and is perhaps one of the simplest electronic casino home games. Though not as complex as its original mechanical counterpart but nevertheless can be pretty amusing to actually build it and witness the results. In one my previous articles I have already explained regarding the pin outs of the IC We have learnt that the output of the IC changes state from a logic hi to a logic lo sequentially in the influence of rising edges of the clock pulse at its pin In this circuit the pulse is generated by the IC This IC is wired as an astable multivibrator, but looking into the figure you can find that the supply line to its timing components has been interrupted through a switch.

This clever modification is done to effectively convert it into a voltage controlled oscillator VCO. On pressing the Switch S1, the reservoir capacitor C1 almost instantly gets charged, also at this point of time a constant stable clock is fed to the IC and the LEDs at its outputs light up in a cyclic manner producing a revolving effect. The speed may be predetermined by adjusting VR1. Now as soon as the switch is released, the main supply is cut-OFF, C1 discharges and transfers its charge to C2 through the pot VR1 and the other resistors on its path.

This forces the freely running astable to gradually stretch and slow down the time period of its output pulses so that eventually the oscillations stop within a stipulated time. This score will always be selected in random way depending on how long the switch S1 remains depressed and thus can never be predicted accurately. Begin by assembling the circuit board first with the help of the given circuit schematic. As usual it may be simply done by inserting all the procured electronic components on a general PCB and interconnecting their leads through soldering.

Roulette has offered glamour, mystery, and excitement to casino-goers since the 17th century. The game is popular in casinos worldwide in part because its rules are relatively simple and easy-to-understand. However, roulette offers a surprising level of depth for serious betters. Before putting it all on black, learn the basics of this thrilling game by reading the detailed instructions in this article below the jump. To play roulette, find a roulette table, hand your chips to the dealer, and place your bets.

The first 6 bets are placed on the pockets numbered on the game table. To bet on a column, place your bets on the empty pocket under the column. For outside bets, use the red, black, even, odd, high, or low pockets.

You can choose numbers randomly or go with your gut, but there's no real strategy for roulette—it's mostly just pure luck! When you're ready to quit, put the rest of your chips on the table and tell the dealer you want to cash out. Roulette is French for "little wheel. Bets are placed on the table, correlating with the slots the ball can possibly land in. On the table are the numbers and a few other options: Know the different "inside" bets.

In roulette, you have to anticipate the number or type of pocket on which the ivory ball is going to land. To do this, there are a range of bets you can make. It can be placed on the end of any "street" the row of 3 numbers on the table map. Corner betting on four numbers pays 8 to 1 The chip lies on the intersection of the four numbers.

Six line betting on 6 numbers pays 5 to 1 The chip lies on the edge of two adjoining streets. Additionally, for American roulette, there is the Five-number bet which covers "0,00,1,2,3" and pays 6: Learn about "outside" bets. These bets do not involve specific numbers and are made on the outside of the number map, hence the name. Color betting red or black pays 1 to 1. Even or odd betting pays 1 to 1. Column or betting on 12 numbers pays 2 to 1 Dozen betting 1st 12, etc. At every roulette table and at every game in the casino itself , the house always has an edge.
