Ib qib kev hloov pauv logic yog siv los hloov qib ib qib mus rau lwm qhov uas yog qhov tseem ceeb rau qee qhov digital chips ua haujlwm.

Cia peb ua piv txwv thaum peb xav upload cov duab kos rau esp8266-01 los ntawm kev siv arduino peb yuav tsum hloov tx logic ntawm arduino rau 3.3v. Raws li arduino qib kev xav yog 5v, nws yog qhov txaus ntshai rau esp8266. Nws tuaj yeem tau txais kev puas tsuaj, yog li peb xav tau qib kev hloov pauv logic.

Cia peb ua qhov yooj yim logic qib shifter siv ob npn transistors. Cov hom kev hloov pauv qib no tau siv dav hauv ntau ntawm cov txuj ci digital. Hauv cov lus qhia no peb tab tom yuav tsim qhov yooj yim Circuit Court ntawm qib shifter tsuas yog nkag siab tias lawv ua haujlwm li cas. Xyaum cmos yog qhov zoo dua rau kev ua cov qib hloov pauv.
