Nov yog yuav ua li cas tsim qhov yooj yim tswj chaw taws teeb tester. Tsuas yog ua raws cov theem hauv qab no thiab koj yuav ua nws qis dua 5 feeb. Yog tias nws ua haujlwm ces thov tawm qhov nyiam ntawm peb cov vis dis aus thiab qhia peb hauv cov lus:)

Kauj ruam 1: Saib Video

Kuv tau qhia tag nrho cov txheej txheem yuav ua li cas thiaj tsim cov phiaj xwm no hauv kuv cov vis dis aus, Yog li yog tias koj xav saib nws tom qab ntawd Txuas yog muab hauv qab no-

Kauj ruam 2: Ua tibzoo saib Schematic

Kauj Ruam 3: Yuav Qee Qhov

Daim Ntawv Teev Npe-

IC1- LM7805 (tsis tsim nyog, Koj tuaj yeem siv ncaj qha rau 6V Roj teeb.

IC2- TSOP4838 (Lwm Yam 38KHz Infrared Txais Tus Qauv tuaj yeem siv tau zoo li TSOP1738. Tab sis ceev faj txog tus pinouts txwv tsis pub koj yuav ci koj IC)

D1- 1N4007 lossis Ib qho rectifier diode (Tsis tsim nyog, Tsuas yog tiv thaiv los ntawm rov qab polarities.

QI- Ib qho twg nquag PNP BJT Zoo li BC557, 2N3906 thiab lwm yam (Tsis quav ntsej NPN Cim ntawm lub tswv yim)

LED- 3V LED 20mA (Txhua xim, Nws tsis yog qhov teeb meem loj)

R1- 47 Ohms (Siv raws li koj lub LED)

Lub Hwj Huam Fais Fab- 9-12V (Tsis txhob siv LM7805 Rau Cov Hluav Taws Xob Hauv Qab 6V)

Kauj Ruam 4: Qhia Teeb Meem

Yog tias koj lub Circuit tsis ua haujlwm, Sim siv phau ntawv qhia hauv qab no thiab pom tias nws ua haujlwm (Yog tias tsis yog, thov hu rau peb hauv nqe lus ntawm peb cov vis dis aus)

1. Xyuas kom tseeb tias koj tus qauv txais tau zoo.

2. Tus txais tus qauv tuaj yeem raug puas yog raug rau qhov siab ua ntej thiaj li yuav qhov tshiab

3. Tus pinouts ntawm TSOP1738 Thiab TSOP4838 Los yog lwm qhov sib txawv yog li xyuas kom koj tau txais kev sib txuas nrog TSOP txoj cai

4. Txheeb xyuas cov kab hluav taws xob luv (Kuv Nyiam siv lub multimeter)

5. Nco ntsoov tias kev sib txuas nrog cov transistors raug

6. Siv PNP Transistor, Yog tias koj siv NPN Tom qab ntawd nws yuav tsis ua haujlwm

7. Soj ntsuam qhov polarity ntawm LED

8. Txheeb xyuas koj lub hwj chim

Kauj ruam 5: Piav qhia

Nov yog cov lus piav qhia luv luv txog peb kev sib tham (Kuv Yuav Tsis nkag mus rau hauv cov ntsiab lus tab sis koj tuaj yeem nrhiav cov ntaub ntawv ntau ntxiv hauv youtube, Google thiab lwm yam) Yog li TSOP4838 yog 38KHz Infrared receiver module, Ob tus lej kawg qhia txog kev ua haujlwm (38KHz) Yog li TSOPxx38 tuaj yeem yog siv. Nws tsuas yog yuav tsum yog 38KHz ib qho. Yog tias koj xav tsis thoob vim li cas 38Khz ib qho ces nws yog vim Feem ntau ntawm kev rov ua haujlwm tswj siv kev sib txuas lus ntawm Infrared teeb uas xa mus rau Tus Txais (Nws tej zaum yog koj lub npov saum toj kawg nkaus, DVD Player thiab lwm yam) ntawm zaus 38 Kilo Hertz. Tam sim no koj yog vim li cas thiaj li txav mus rau lwm yam khoom. Yog li thaum twg khawm tau nyem rau ntawm cov chaw taws teeb tswj tus txais txais nws thiab tso tawm 0V (Yog vim li cas peb thiaj siv PNP Transistor) Thiab thaum nws tso tawm 0V Lub transistor hloov pauv, Lub Circuit Court ua tiav thiab LED Glows ntawm 47 Ohm resistor. Cov coj flickers vim hais tias lub teeb infrared los ntawm cov chaw taws teeb tswj tsis sib xws, Txwv tsis pub koj tuaj yeem siv qhov qub IR LED Los tswj koj cov khoom siv. Lub teeb hluav taws xob no tau xa mus rau qhov luv luv uas DVD Player lossis txhua yam txiav txim siab thiab hloov nws cov zis, Txhua lub khawm muaj cov lej sib txawv, Tias yog vim li cas peb LED Glows hauv luv luv. Txhawm rau tshem tawm qhov flickering ntawm LED, Tsuas yog tso 10 rau 100 micro Farad capacitor sib npaug rau LED. Txoj kev ntawd thaum TSOPxx38 Tso Tawm LED Glows thiab lub tsub them nqi ib yam nkaus, Thiab thaum cov zis raug kaw, Lub tshuab hluav taws xob tso nws lub zog rau LED thiab nws zoo li LED tau ci txhua lub sijhawm. Qhov ntawd yog txoj cai?:)
