Hi,
I built the 10 led sequencer described here in the first picture. I am pretty sure that I put it together correctly but there are some problems. First I think I should mention that I am using a home made power supply to power the circuit and that it is very close to the breadboard that I am working on.
I have my power supply on 9v and the circuit seems to just run randomly. It will have one led on then all the leds will light a little bit then the first led will be back on, and that just keeps happening. I was getting very frustrated at it but I did discover that if I turned my power supply down to 6v the whole circuit would run fine.
I just noticed that the voltage on this specific circuit is actually 6v. I feel incredibly stupid. I have see other similar circuits that had shown 9v for the power and hadn't noticed that this one was 6v. oops. I guess I just fixed most of my problem. oh well, I just wrote all of that so I may as well ask another question. I tried hooking this circuit up to a 9v battery and it worked. Why does it work on a battery when it wouldn't work on 9v from the power supply?
thanks for any and all feedback,
