Cov Khoom Siv Hluav Taws Xob Me Me Koj Yuav Mus Li Cas?: 6 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

qee lub sijhawm dhau los Kuv tau txais lub teeb me me (ntawm PCB xim av) los ntawm ib tus ntawm kuv tus phooj ywg nws yog lub tsev tsim hluav taws xob teeb lub teeb nrog built-in them Circuit, LiIon roj teeb, DIP hloov rau hloov xim ntawm RGB LED thiab tseem hloov tag nrho Circuit Court ntawm

tab sis dab tsi feem ntau nyiam kuv qhov kev txaus siab yog qhov ua rau pom qhov tsaus ntuj heev

pom tseeb kuv xav tau cov phiaj xwm ntawm nws tab sis nws yuav los ntawm ib tug txiv leej tub ntawm qee qhov chaw muag tsheb thiab nws tsis paub dab tsi txog nws txawm tias nws yog dab tsi ua ntej nws coj nws tuaj rau kuv tab sis nws muab rau kuv vim nws tsis muaj siv rau nws

Hmoov tsis muaj tsis muaj lwm txoj hauv kev xaiv tsuas yog txiav nws vim tias cov khoom siv hluav taws xob tau txuas mus tas li nrog silicone thiab tsis muaj qhov pom meej nyob rau sab hauv qab ntawm sensor PCB vim tias nws yog qhaub cij ua ke nrog them nyiaj PCB board

yog li kuv Dismantle nws, theej schematic thiab ua thawj qhov kev sim nrog SMD transistors thiab qee qhov tiv thaiv uas kuv twb muaj thiab kuv tseem ua PCB board hauv dav dawb hau (CAD software)

Kuv ib txwm xav ua qee qhov kev sib tw me me tsis muaj PCB yog li kuv hu kuv lwm tus phooj ywg thiab nug nws yog tias nws muaj SMD resistors uas kuv tsis muaj thiab nyob rau hnub tom ntej kuv tau ua kuv thawj qhov me me Circuit:)

nws yog kev xav ntau thiab kev tsim kho thaum kuv tau muab cov khoom sib xyaw ua ke tab sis kuv zoo siab tshaj nrog qhov txiaj ntsig kawg yog tias koj txaus siab xav saib kuv cov kauj ruam thiab sim qee yam zoo ib yam

Kauj ruam 1: Yam Koj Yuav Tsum Tau

1. thoob ntawm kev ua siab ntev

2. tag nrho cov khoom siv xav tau

3. "thib peb txhais tes" lossis qee tus tuav rau SMD cov khoom

4. zoo tweezer

5. soldering hlau nrog lub taub ntse thiab nyias cov hlau txuas nrog cov tub ntxhais flux

6. tus ciaj rau txiav tus pin

7. iav tsom iav thiab lwm yam khoom siv pab tau

Kauj ruam 2:

1. solder 103 (10k) resistor ntawm puag thiab emitter

2. tom qab ntawd txuas lub hauv paus ntawm transistor rau ib tus pin ntawm photoresistor thiab koj tuaj yeem txiav ntev ntev ntawm LDR tus pin

Kauj ruam 3:

3. txuas cov xaim me me rau tus sau ntawm transistor thib ob (nws yuav raug rho tawm rau LED tom qab)

4. thiab txuas cov hlau txuas mus rau emitter ntawm thawj transistor soldered ntawm photoresistor (qhov no yuav txuas tom qab txuas nrog emitter ntawm transistor thib ob thiab ua haujlwm hauv av ntawm Circuit Court tiav)

Kauj ruam 4:

5. txuas 102 (1K) resistor nruab nrab ntawm tus sau ntawm thawj lub transistor thiab lub hauv paus ntawm transistor thib ob

6. solder 103 (10K) resistor rau tus sau ntawm thawj transistor

Kauj ruam 5:

7. ntxiv 472 (4K7) resistor nruab nrab ntawm qhov kawg ntawm yav dhau los ntxiv 10K resistor thiab tus pin tsis txuas ntawm photoresistor

hauv qhov no koj tuaj yeem txiav ntev ntev ntawm tus pin ntawm photoresistor tab sis nws tuaj yeem ua tus tuav taw tes rau kev tswj hwm

8. txuas cov hlua txuas ntxiv hauv daim duab 4 mus rau tus xa hluav taws xob thib ob thiab txuas cov xov hlau tshiab mus rau qhov sib koom ua ke ntawm 472 thiab 103 tus tiv thaiv ntxiv hauv cov kauj ruam dhau los (duab 6 thiab 7) nws yuav yog VCC xaim ntxiv LED diode ntawm VCC hub thiab me ntsis xaim ntxiv hauv daim duab 3

Kuv siv ntsuab LED yog li kuv tsis ntxiv tus tiv thaiv rau nws tab sis yog tias koj xav siv xim txawv koj yuav xav tau ib qho 50-100Ω yuav tsum txaus rau lwm cov xim (tsuas yog koj siv 3V qhov chaw)

Kauj Ruam 6:

txuas 3V rau koj lub Circuit Court thiab yog tias nws teeb hauv qhov tsaus ntuj koj tau ua tiav:)
