I am looking for a simple way to generate a pulse of 5 seconds from a momentary pushbutton. I thought about the 555 timer, but I only have 3 volts. I understand there are low voltage versions of the 555 timer but between availability and other factors, I am thinking about other options.
Does anyone have advice on a simple low cost method to do this? Basically take an edge and create a several second pulse?
Thanks in advance.
