I joined just because I'm having sort of a dilemma. I need to design a flash circuit for a tiny SMD based project, and I have a way of doing it, but I want to see if I can make it better and I haven't had any luck for days.
Basically I'm using a 555, in a monostable configuration, which would actually be okay but I want to do better if I can.
I want two simultaneous flashes from the LED, but I'm having no luck. I've tried running parallel 555's, but no luck either.
I also tried an RC circuit, but I dislike how the LED discharges slowly, plus I can't get multiple flashes out of it, which is why I'm using the 555 approach. I like how the 555 just flips the LED ON\OFF and doesn't fade with the cap's discharge. Furthermore, the SMD chip and total solution is pretty tiny.
So basically how do I make this circuit flash the LED twice? Is it even possible with the 555?
PS: I'm sure my values and placement are probably baffling everyone right now. I'm not an EE, but I am learning fast, so if there's other corrections, let me know by all means :)
