a good hard ... allows easy soft !!!
Hi, Castor
May be there would be a smart turnaround ...
if , instead of R1, you use a constant current generator ...
say a PNP trans, with a red led between VCC and base, a resistor between emitter and VCC to fix your current ...
and another resistor between base and GND to allow, say, 1 mA into the led + trans base.
good idea, no ???

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
