I am trying the ShftOut tutorial
I am using an Uno and I have the 74HC595 shift register.
I have built my circuit exactly the same as the example except I don't have the .1F cap installed. According to the tutorial, the cap is to eliminate flicker, so I don't think that is my problem.
What I am seeing when I run the program is that all of the LEDs flash at the same time. All on, all off, all on, all off. But every once in a while I do see a different pattern, but the next cycle it is back to all on or all off.
Any ideas what may be causing this? I have double checked the wiring and I think I got it right. And the code is just a copy and paste of the Hello World example on that page.
