I am designing a water level controller using Arduino Duemilanove.
When i restart the micro-controller all the output pins toggles turning on the relay (connected to pin 13) for few milliseconds. How can i overcome this problem ?

The bootloader flashes the LED on Pin 13 on boot.  So either program the chip directly (removing the bootloader) with a programmer or don't use Pin 13.

Thanks a lot Sir. I will use pin 11 for triggering relay.
