Obviously we don't know how your hardware looks, what you are trying to do, what your software looks like or even what is going wrong (bit hard without knowing the earlier stuff).
The only thing you've given enough info for, is me asking what supply voltage the external power supply gives?
It should be between 7 and 12V, below 7V and you risk voltage spikes dropping it below the absolute minimum of 6V which will make your arduino restart.
Above 12V and you risk burning up your arduino.
Hope this helped.
Welcome Papor!
Why dont you post the code? and explain in detail how you tried? Without that information, it would be difficult for anyone to help.
Cheers,
Pracas
