Hi there,
I have been trying to make a circuit that:
when you turn it ON it lights up 10 LEDs in sequence (1,2,...,9,10) until they are all lit (and stay lit)
And when you turn it OFF they turn off in sequence backwards (10,9,...,2,1) until they are all off (and stay off)
I have come up with this circuit (see attachment). I have tried it in a simulator and all seems to work well. However when I assemble it in mybreadboard, it doesn't light up any LED.
I'm a newby in electronics and I just have a few basic knowledge.
So could someone please help me sort out what might be wrong with my circuit? Our if you have a better ideia for a circuit that makes the effect I want, I would appreciate your suggestions.
Thank you in advanced!

P.S: I have came across with Popicop post that is exactly what I want to do, but there isn't any circuit that I can have a look at (https://www.electro-tech-online.com/threads/10-led-sequence-light.25342/?highlight=lm3914).
