plz can any explain it and make it properly??? or any software simulation????

This screenshot shows a simulation for a similar request a few months ago.

It uses a 555 and 4017, in a similar fashion as your diagram.

Can you please upload the simulation file?

Clicking this link will open the website www.falstad.com/circuit, load my schematic, and run it on your computer.

To re-run the simulation, click the Reset button.

When you click Export a window opens containing the data file. I do not believe it is in Spice format.
 

i made this on vero board, my 555 pulse generator is working fine, as i place LED there, and its blinking properly, but the 4017 part doesnt work like it showing in simulator plz help

here is what i did, but the LED, ALWAYS keeps ON :(

The 4017 has a Reset pin which must have either 0V or supply V applied to it. It cannot be left unconnected.

Your schematic shows no wire going to the Reset pin.

By the way, I realize my simulation has no supply or ground going to the 4017. This is to simplify the layout. It is okay that your simulation shows a supply and ground connection.
