Can anyone provide me a design for an astable multivibrator using 555.
The output of the 555 (pin 3) must be in High State for 0.5 Secs and LowState for 3Secs.Any pros please help.....
I'm just a rookie.....
Thanks...
You will find this information in the data sheet. You can also find the data sheet free on the net. Just google 555
