Blinking leds
Blinking leds
Is it possible to construct a circuit that will flash(blink-turn on then off)one to three leds and be powered by several AA cells or 9v battery? Thanks Paul

Hi Paul,
This may be oversimplifying things, but DigiKey has T-1 3/4 size LED's that have built-in circuitry to flash at 1.5 to 2.5 Hz at operating voltage of 3 to 14 volts input. I'm sure there are plenty of others available, but I just cracked open the nearest catalog for this reply. A search on "flashing led" or even "blinking led" will probably provide tons of information. Hope this helps,
Dave

If you really want to learn about how to blink LEDS, you could take a look at this page: http://www.apogeekits.com/flashing_lights.htm
There's a kit on the page for sale, but the page also includes a schematic and a description of how the circuit works which you could take a look at.

radio shack used to carry them, i do not know if they still do or not.. i made me a really nice blinky flash christmas tree for my desk at work here,that had been made strings of leds and a blinking led in series.
this made the whole string blink,,and i had several strings blinking.
looks awsome.. i will try and post a foto later on,,i do not know if i can post a video of it or not...anybody know how i can do that ?

Thanks for the replies. I would rather build than buy and went to the site suggested. They have a schematic and I will follow that. Paul
