Thanks for your inputs, much appreciated,
Not that I know of @Old_Grey, had a quick squizz at the data sheet could not find anything.
@vanepp I placed the capacitors as suggested to no avail. I think it does not work because they don’t have time to charge up or they are not big enought!
What I did discover is that if i moved the LED outputs from pins 2 and 16 to pins 0 and 16… it works!
Holding down the reset button i took the volltage from pins 0, 16 and 2(the problem pin) to ground and got:
3.1v pin 0
3.2v pin 16
3.3v pin 2
would this have anything to do with it? I would think not as @vanepp said the voltage does not matter it is the current that is amplified by a tip122g darlingotn.
SO… maybe it is the type of pin (pin 2) that is causing it? if you look at the pinout diagram for thr huzzah feather it labels pin 2 as TXD1, would this have anything to do with it?
maybe it is has something to do this bit of info from the adafrui website this, found here.
