VIP LED Project with CD 4017 IC

This is a useful and simple circuit created with CD4017 and the most famous NE 555 IC. If you want to add more LEDs ,you can use more powerful Transistors
and if connect a relay to the output, you can connect 230v bulbs as well.
However, this project is only for the fun and it may not legal to use in the
public in come countries.

Following Parts are required

1. CD 4017 IC 


2. NE 555 IC


3. RED LED = 12 Nos


4. Green LED = 12 Nos


5. 100ohm = 2 Nos


6. 10k Resistors = 4 Nos


7. 1N4001 Diodes = 1 Nos


8. 1N4148 Diodes = 6 Nos


9. S8050 NPN Transistors = 2 Nos


10. 50k Presets = 1 Nos


11. 103k ceramic cap = 1 Nos


12. Copper board/Vero Board


13. Ferric chloride(for PCB)
