I just got my 556 timers and I wired it up just like the 555 but now: it flashes one HighTime and stays off then...
I used this calculator and basic diagram: http://www.ohmslawcalculator.com/555-astable-calculator
And changed it to fit the 556:
You guys have any idea why this is not working?
(P.S.: I used green wires here if lines are overlapping)
