so i am okay with using the level shifter for issue 1,
but for issue 2,
why cant i use a current limiting resistor? in the previous arduino post, an E-12-82R was calculated for that specific display. another forum member used a E-12-56R without issues.
the other option
i build a votage divider, wouldnt it just be easier to buck the load LED pin a cheap buck coverter? if that is the case, how would that be connected to the circuit?
