Hello All
I am looking for help on 555 timer circuits.I have searched the net for info and I have learned quite a bit on the way.Unfortunatly I have not quite found what I am looking for.
I want to control a 555 to give out pulses of 1 sec for a 30 sec period. then stop and wait for the next trigger.I am led to believe that I will require two 555's for this purpose.?
The circuit would have to be able to be manipulated for other user impulse periods.I do realise that this can be done via combinations of caps and resistors.
The main question is the longer periods.
Kind regards wombweller
