hi, all

I'd like to design a little LED light that will flash at a certain frequency. My plan is to make it as a toy in my car, which looks like an alarm indicator.
here is my problem. I have purchased a few LEDs from RadioShack(they are a lot more expensive than the ones in Frys), i don't know how to design it so that it will flashes?
Do i have to use an AC source? can i accomplish it by using a DC source, such as a battery.


Thanks,

isaac

If you're already buying more expensive components at RadioShack, just buy the flashing LED. Then all you need is a resistor.
