Lub Teeb Ntes, Tsis Muaj Microprocessors, Tsuas Yooj Yim Siv Yooj Yim :): 3 Cov Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Kuv yuav qhia koj ob txoj hauv kev, ib qho tig LED tawm thaum tsis muaj lub teeb, thiab lwm qhov tig LED thaum tsis muaj lub teeb.

rau thawj tus koj yuav xav tau: -R1 (LDR) 10K -R2 (1.2K) xim xim: xim av, xim liab, liab. -R3 (10 ohms) xim xim: xim av dub dub. -T1 yuav luag txhua qhov hluav taws xob qis NPN transistor yuav ua. -L1 LED kuv siv liab. -potenciometer (yeem) -cov xov hlau -breadboard -2 1.5 volt bateries thiab ntim rau lawv rau qhov thib ob koj yuav xav tau: -R1 (LDR) 10K -R4 (10K) xim xim: xim av, dub, txiv kab ntxwv. -R3 (100 0hms) xim xim: xim av, dub, dub. -T1 ib qho hluav taws xob qis NPN transistor -L1 LED kuv tau siv liab. -potenciometer (tsis teb los tau) -cov xov hlau -breadboard -2 1.5 volt bateries thiab ntim rau lawv nws raug nqi kuv qis dua 1 € los ua qhov no, txhua yam tau khaws los ntawm cov xov tooj cua qub, thiab lwm yam … zam lub LDR, tab sis koj tuaj yeem yooj yim tau txais ib qho los ntawm cov ntawd teeb hloov khoom ntawm lub khw duas las, lossis los ntawm internet pheej yig heev… ntxiv qee yam khoom ntxiv yog tias koj tau txais los ntawm net txawm hais tias… koj tsis xav them 10 xees rau ib feem thiab 8 daus las rau kev xa khoom = |

Kauj Ruam 1: Tua LED Tawm Thaum Tsis Muaj Lub Teeb

1.2 K resistor mus rau hauv nruab nrab tus pin ntawm transistor thiab rau - ntawm roj teeb tsis txhob hnov qab qhov hloov pauv ib feem ntawm lub transistor tab tom ntsib koj!

Kauj Ruam 2: Qhib LED ntawm Qhov Tsis Muaj Lub Teeb

nws yog ib puag ncig zoo ib yam tab sis LDR tam sim no mus rau - thiab R4 (10K resistor) mus rau ntxiv.

txhua yam koj yuav tsum ua yog qhov kev hloov pauv me me no thiab tag nrho lub hom phiaj ntawm kev hloov pauv hauv Circuit Court! tsis txhob hnov qab puag ncig ib feem ntawm lub transistor tab tom ntsib koj! Tsis txhob hnov qab POLARITIES ntawm LED !!! yog tias koj muaj kev ua xyem xyav/teeb meem plz qhia kuv.

Kauj ruam 3: Cov ntawv txuas ntxiv

Tam sim no kuv yuav sim piav qhia qee yam ua.

ntawm thawj Circuit Court 1.2K resistor tswj kev nkag siab, mus tom ntej hloov nws! yog tias nws yog 10K koj yuav xav tau tag nrho qhov tsaus ntuj kom tig lub LED tawm, yog li hloov nws li 1K thiab 10K tsawg dua 1K yuav yog txoj kev nkag siab thiab tsis ua haujlwm, thiab ntau dua 10K koj yuav xav tau qee yam tsaus dua li qhov tsaus ntuj, uas kuv tsis xav tias muaj, tej zaum qhov chaw sab nraud: P qhov thib ob Circuit 10K tus tiv thaiv kuj tseem tswj qhov rhiab, yog tias koj tso 150K koj yuav xav tau tag nrho qhov tsaus ntuj kom tig lub LED rau, yog li mus ahed hloov nws ib yam! tab sis tsuas yog betwen 1K thiab 150K. Yog tias nws tsis ua haujlwm: txheeb xyuas qhov sib txawv ntawm LED, thiab pom tias lub transistor yog txoj hauv kev yog, yog tias LED tsis mus, ntawm thawj Circuit Court, tsis txhob tu siab, lub Circuit Court tau kho kom nws ua haujlwm hauv kuv chav, tsuas yog tuav lub potenciometer thiab kho nws raws li koj xav tau, tom qab ntawd nrog lub ntsuas ntsuas nyeem qhov tsis kam ntawm lub lauj kaub, thiab muab qhov tiv thaiv ze tshaj plaws uas koj tuaj yeem pom rau qhov rov ua dua, yog li kuv tau txais 1.2K thiab 10K qhov zoo tshaj plaws! Tam sim no cov vis dis aus ntawm yam koj yuav tsum tau txais:
