I don't think you connected the grounds, Dave.

Look carefully at the relays.
Tell me how they're supposed to work.
Think "electrical circuit".

dear if voltage is applied to the diode this will pass the voltage to the relay and motor will be connected and if the voltage gets off pin get disconnected and the inductor in the relay will be dischrged that'll produce back emf so for that i have placed a diode for that

Most relays I've seen need at least two wires connected to them to energise the coil.
That's why I said "think electrical circuit".
( I hope this thread isn't going to degenerate into another "pulling teeth" sessions)

How does your "circuit" allow current through the relay coils?

You may be asking a bit much.  |

you can tell me if i am missing
You should put Ground symbols on all of the parts that are connected to Ground. Current won't flow into the relay coils unless the other side of the relay coil is grounded. |

Why did you ground pin 9? That ain't gonna get you very far... /pulling teeth, indeed!  |

My bad - was reading your schematic wrong...  |

Still not seeing very much decoupling or common grounds.
