I am looking for a circuit, possibly using the 556 timer, which will flash an led with two quick flashes then a pause, two quick flashes then a pause, etc.
Ideally a circuit that I could easily change to select the number of flashes (eg change from two quick flashes to three quick flashes).
Any help would be much appreciated.
