    thats a circuit to make them blink correct ?? im just looking for blinking led's so i dont have to build a few circuits

    or should i buy regular LED's and build the 555 timer for tons of LED's ?? witch do u think would be better ??

    Hello,

    An 555 circuit will give you more freedom on how the leds are flashing.
    (you can adjust the flash-rate and the flash-time).
    Leds with biuld-in flash circuits will have different flash-rates that can not be controlled.

    Hello,

    Just take a look at the blog I gave you.
    Bill is a master in NE555 / led circuits.

    Still after the double flashing circuit?

    If you're just learning to do this I highly recommend a protoboard, it is much easier than soldering.

    What part of the world do you live in? This dictates where you can get parts.

    Mouser Electronics, www.mouser.com has blinking LED's in stock for less than $1 each. Go to the website in search for blinking LED.

    I have used blinking LED's in series with standard LED's to blink strings of LED's. Most of the blinking LED's that I have used will work on a fairly wide range of voltages.

    Yes, blinking leds do, in fact, blink. However, with the minute difference in forward voltages from led to led, you will have a heck of a time if you want 2 or more to blink at the same time or rate. Using a circuit will give you control over all of that. And for 10 cents or less for standard LEDs, and $1 for blinkers, it depends on the finished project.
    Are you using more than 1 led in your design?
