Hello,
I'm trying to design a circuit that would produce an output pulse (.5-1 seconds) when double pulse on the input is detected with a time gap of <=.5 seconds.
It looks to me like something that could be done with 555s, but I don't have enough experience to produce it myself and google did not reveal anything
This is supposed to be a gadget that activates a garage opener on the double-tap of the "flash-to-pass" switch on the motorcycle. Devices like this are available commercially, but I'm not paying $100 or so when I can build it
Thank you very much in advance for suggestions.
