yes but Now my IC is not working its not Loading the Program

that Is unfortunate.  Time To replace That Ic.

i want to now what i have done wrong with my arduino that my IC is not working

AWOL

Please, everyone, hands on the ouija board.

thats a good Question John
But i have done some work to see my IC is working but my IC is doing good on My friends Board
Why its Not working on my Board

That question brings us back to Reply #8:

1) Programming error
2) Insufficient RAM
3) Electrical problem such as voltage drop.

i think that Programming is not the Issue the Voltage Drop is the Issue because i have made my own arduino On PCB
what should i check Transistors,Resistor or capacitor

AWOL

I'd try to unstick your shift-key too.

the when it on Moving Left it require a Lot of power to move it i think that the motor and the relay is Producing Back emf i have place diode for it and don't know the other concerned issue


Please - post some pics of your setup, your board, your schematic, your code...!

Are you saying it takes more power to move it to the left than to the right? If it is the same motor, that could be a mechanical issue?

Do you have decoupling caps on your Arduino board?

Are the relays identical to each other? How are they wired (once again - pics and a schematic could help us immensely)...?

If the motor is producing a lot of back EMF (or EMF in general - do you have caps across the terminals, and to the case of the motor?) - have you measured the noise using an oscilloscope (mainly between the line from the Arduino and the Arduino's ground) - to see if any back EMF is being injected in some manner that could cause a reset?

Does the system work correctly when "toggled" by hand - that is, when applying 5 volts/ground simulated HIGH/LOW to the transistors that control the relays (just like the Arduino would)? Have you tried using an optocoupler (well, probably two in your case - one for each relay) to completely isolate (both signal and ground) the Arduino from the motor controller?
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

ok

I want to know why my board is getting reset i have attached the circuitry with it

AWOL

How are those relays supposed to work?

when the my Control will send high to the ULN2003 it will pass it to relay and the following relay will switch to ON

-->if the Right relay will On the motor will run clockwise
-->if the Left motor will get on the Motor will run anti-clockwise

AWOL

I think there is much still missing from your schematic.

no this is it

you can tell me if i am missing
