Hloov thiab Push Buttons feem ntau yog siv los ua cov khoom siv nkagrau cov kab ke digital. Cov zis hluav taws xob tuaj yeem hloov pauv ntawm Vdd thiab Gnd los ntawm nias / tso lub laub khawm lossis zawv zawg qhov hloov.
Puas yog hloov pauv tswv yim lossis tso tawm?
cov khoom siv nkag muaj xws li lub teeb-dependent resistors (LDRs), thermistors thiab piezoelectric sensors. cov txheej txheem muaj xws li keyboards thiab resistors. tso zis cov khoom siv suav nrog cov hais lus nrov thiab lub teeb-emitting diodes (LEDs)
Lub cuab yeej twg yog qhov kev tawm tswv yim lossis tso tawm?
Ib qho input device yog ib yam uas koj txuas rau lub computer uas xa cov ntaub ntawv mus rau hauv lub computer. Cov khoom tso zis yog ib yam uas koj txuas rau lub computer uas muaj cov ntaub ntawv xa mus rau nws.
Puas yog coj ib qho kev tawm tswv yim lossis tso tawm?
Ib qho tshwj xeeb tso zis ntaus ntawv : Lub teeb Emitting DiodeNyob rau hauv qee lub voj voog tam sim no hauv LED Circuit Court yuav tsum raug txwv kom tsis txhob ua rau LED puas. A series resistor yog siv los txo qhov tam sim no hauv Circuit Court thiab xyuas kom lub LED tsis puas.
Dab tsi yog cov khoom siv tawm tswv yim?
Ib lub tswv yim / tso zis ntaus ntawv, feem ntau hu ua IO ntaus ntawv, yog txhua yam khoom siv uas tso cai rau tib neeg tus neeg teb xov tooj lossis lwm lub tshuab cuam tshuam nrog lub khoos phis tawj Cov khoom siv tawm tswv yim / tso tawm, xws li lub npe implies, muaj peev xwm xa cov ntaub ntawv (tso zis) rau thiab tau txais cov ntaub ntawv los ntawm lub computer (input).
