Yeah I thought faulty/odd vReg problems as well..but switched it out with another one.. same results?!!
Lacking much electronics/hardware experience.. I feel a bit 'dead in the water'..
Hoping I didnt damage anything...
I popped out both chips I have and put them in my Arduino board.. fired up..worked fine.. steady..
throw either of them in my two breadboard layouts.. same problem..
maybe the vRegulator I got in the list is wrong? (I didnt look at spec/data sheet)
if I turn up the PSU voltage.. while running.. I can see a visual difference in the led brightness... eventually stopping the blinking..
hmm.. anybody?
