I've been working through some of the examples getting ready for my own project and I've stumbled upon a problem when doing the Serial to Parallel Shifting-Out with a 74HC595
example. I'm using a 74HC595N and I've ripped the example apart around 4 times, and everytime I seem to get the same problem.
My LEDs seem to go "wrong" at around binary 5 or 6. Then they just seem messed up until I can see the counter starts again. I'm pretty sure I've got something wrong as they are also dipping in power on some numbers, as if there is a bad ground or something, but I've checked for shorts bad connections and can't see anything.
I was wondering if anyone could help me with some ideas on what could be wrong. I've posted a video of the problem and a picture of my project on my Google+ page here
and I've attached the picture to this post. I'm sorry for the yellow wires I realise this may make tracing the cables difficult, I'm waiting for a delivery of jumper cables - I knocked these home made tinned ones up myself so I could get on with playing
Thank you in advance!
