- 555 Timer IC: A popular chip used for generating accurate time pulses
- Two 4017 Decade Counter IC's: There are used for counting applications and can count from 0 to 9 sequentially
- Resistors and Capacitors: For setting the timing of the 555 timer
- LEDs: To display the roulette output
- 9V battery
- Breadboard and connecting wires: For assembling the circuit without soldering
- Push button: To start the roulette
- Diodes: To prevent backflow of current
- Capacitors: Control pulse waves
Setting Up the 555 Timer

- Configure the 555 timer in Astable Mode and add a push button
- The output pin of the 555 timer will provide clock pulses for the 4017 counters
Connecting the 4017 Decade Counters

- Wire the first 4017 IC: This will be the primary counter
- Connect the output of the 555 timer to the clock input of the 4017
- Connect the LEDs to the output pins of the 4017
- The LEDs will light up sequentially based on the clock pulses
- Chain the second 4017 IC: To extend the count 10's digits
- Connect the last LED's input of the first 4017 to the clock input of the second 4017
- Attach more LEDs to the outputs of the second 4017
Testing

- Check connections: Ensure all components are correctly connected
- Power on: Apply power to the circuit
- Operate the Roulette: Press the button and observe the LEDs. They should light up sequentially, mimicking a roulette wheel
