Connect U1 pin 7 to pin 6. Pin 7 is the Discharge output, which discharges the timing capacitor C2 at the end of a timing cycle so it is ready for another cycle.

Late to the party. To clarify the requirements, please choose one option -

1. When the button is pressed briefly, the LEDs come on steady for 16 seconds.

2. When the button is pressed briefly, the LEDs flash for 16 seconds.

3. Other.

Thank you, I'll give this a go and report back.

In the end I went for: "1. When the button is pressed briefly, the LEDs come on steady for 16 seconds."

So the title of the thread is somewhat misleading now, apologies.

Not a problem, it happens often around here. Someone asks a question about what they think they want, but after some discussion they realize that their original question was not the real question. This site is better than most (and way better than some) at this kind of flexibility.

Not going to lie, you've lost me here

Thank you so so much! This was the missing link, it now works repeatedly without needing to manally discharge the capacitor... who'd have thought the discharge pin was for that...


Just need to put it all together and put it into the toy now and I can call it a job well done.


Thank you to everyone who has contributed to this thread and for having patience with me, I really do appreciate everyones help
