Best Roulette LED Circuit using 555 timer IC
Required Components
- Resistors - 220 Ohm, 1k and 10k
- Breadboard and connecting wires
Roulette LED Circuit using 555 timer IC, before starting the tutorial let you know about what the roulette is, it’s a casino game named after the French word which means little wheel. As same, here we are making a wheel (or circle) shaped led blinker, using 555 timer IC placed in Astable mode, and IC 4017 which is decade counter IC and small needful components.

PIN NO. |
PIN Name |
PIN Description |
1 |
Q5 |
Output 5: It goes high when the counter reads 5th clock pulse |
2 |
Q1 |
Output 1: It goes high when the counter reads 1st clock pulse |
3 |
Q0 |
Output 0: It goes high when the counter reads 0th clock pulse |
4 |
Q2 |
Output 2: It goes high when the counter reads 2nd clock pulse |
5 |
Q6 |
Output 6: It goes high when the counter reads 6th clock pulse |
6 |
Q7 |
Output 7: It goes high when the counter reads 7th clock pulse |
7 |
Q3 |
Output 3: It goes high when the counter reads 3rd clock pulse |
8 |
GND |
Ground PIN |
9 |
Q8 |
Output 8: It goes high when the counter reads 8th clock pulse |
10 |
Q4 |
Output 4: It goes high when the counter reads 4th clock pulse |
11 |
Q9 |
Output 9: It goes high when the counter reads 9th clock pulse |

CO –Carry out |
Used to cascade another 4017 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. |
13 |
CLOCK inhibit |
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. |
14 |
CLOCK |
Clock input, for sequentially HIGH the output pins from PIN 3 TO PIN 11 |
15 |
RESET |
Active high pin, should be LOW for normal operation, setting HIGH will reset the IC (only Pin 3 remain HIGH) |
16 |
VDD |
Power supply PIN (5-12v) |
