555 timer
555 timer
(OP)
Hi,
I would like to connect power to a 555 chip and have the output light up, a led, once for about 3 seconds then go of, then light up again,for three seconds and go of again, but this time stay off.
I dont know much about electronics, im only learning, but i can make a simple timing circuit, but not sure how to stop the cycle after those few blinks.
If you could discribe some way how i can do this, it would be fantastic.
Thanks

I read that thread, but i think he wants his to keep repeating, i want my to stop after a couple of blinks.
Thanks for the replys

take a second 555 with an interval that is two pulses long,
use the second 555 to disable the first 555
or logic gates....
