I am trying to learn how to make a shift register work. I have been working off of the Arduino ShiftOut tutorial.
My issue is that the shift register isn't working when the circuit is powered and I am not sure what is wrong. I suspect the issue is with pins 10-13 on the 74HC595?
I have done this with an actual board and the 123d.circuits.io simulator with the same result:
Oh, Good Lord - No!
It would be from pin 16 to Gnd.
De-coupling is something that can be made way too big a deal out of (now somebody will reply as though I insulted his Mom - wait for it...)
It would be 0.1uF (rated 10V or more.)
May I ask what is the reasoning for deciding the decoupling capacitor's capacitance?
Obviously I'm not referring to the difference between 0.1uF and 100nF... I'm a noob, but not that much....

Habit, it is good enough most of the time. At one place I worked then 22nF was the standard because those caps were marginally cheaper and we made boxes by the million.
