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

Ib feem tseem ceeb ntawm txhua qhov haujlwm hluav taws xob yog hluav taws xob. Koj tuaj yeem siv cov roj teeb tsis muaj qhov kawg, lossis siv lub zog yooj yim, muab lub zog kom muaj zog tag nrho koj cov phiaj xwm hluav taws xob. Nov yog qhov pib ua haujlwm zoo hluav taws xob rau cov uas nyuam qhuav nkag mus rau cov khoom siv hluav taws xob, lossis txoj haujlwm lom zem rau cov neeg uas tsis xav poob nyiaj ntsuab rau cov qauv lag luam. Lub tshuab hluav taws xob no muaj peev xwm muab hluav taws xob hloov pauv tau los ntawm 1.5 volts mus rau 12 volts.

Kauj Ruam 1: Qhov Chaw

Txhua yam hauv qab no tuaj yeem pom ntawm koj li RadioShack hauv zos. Koj tseem tuaj yeem tshem tawm feem ntau ntawm txhua qhov ntawm no yooj yim los ntawm cov khoom siv hluav taws xob qub. 1 LM317T Kev Kho Hluav Taws Xob Hluav Taws Xob - 276-1778 Qhov no yog lub ntsuas hluav taws xob hloov pauv. Nws siv cov tswv yim los ntawm ob tus tiv thaiv (R1 thiab R2) thiab tom qab ntawd ntsuas qhov ntsuas hluav taws xob kom haum. Kuv pom zoo kom koj saib cov ntaub ntawv yog tias koj xav kawm paub ntau ntxiv txog ntu no. 0-5K Linear Potentiometer-271-1714This yog R2, thiab yuav tso cai rau peb los tswj qhov hluav taws xob tso tawm. 1 560 Ohm Resistor-271-1116This yog R1.2 1N4001 Diodes - 276-1101 Muaj ob lub diodes los tiv thaiv luv Circuit Court. D1 yuav tiv thaiv tus tswj hwm los ntawm lub capacitors tso tawm yog tias lub zog nkag tau luv. D2 yuav tiv thaiv tus tswj hwm los ntawm lub capacitors tso tawm yog tias lub zog tso tawm luv luv. 1.1 uf Capacitor - 272-135This lub capacitor (C1) ua raws li lub tshuab ua kom du. Nws yuav tsum tsuas yog cov khoom siv hluav taws xob ceramic. 1 10 uf Capacitor - 272-1013'This capacitor (C2) txhim kho qhov kev teb tam sim ntawm tus tswj hwm. Nws yuav tsum yog electrolytic.1 PCB mount SPST hloov-275-645 Tso cai rau koj tig lub zog rau thiab tawm yam tsis tau ntsaws rau ntawm phab ntsa-wart.1 PCB mount davhlau ya nyob twg sawb-276-1388This yog ncaj qha mus rau lub PC board thiab yog txoj hauv kev yooj yim txhawm rau txuas koj lub zog siv rau ntau qhov sib txawv thiab cov khoom sib txuas. 12 12v Phab Ntsa-Wart Muab lub zog rau hauv Circuit Court. RadioShack muaj qhov xaiv zoo, tab sis kuv pom zoo khaws koj tus kheej ib yam li kuv tau ua. Txhua yam yuav ua haujlwm tsuav yog qhov tso tawm tam sim no tsis ntau dua li amp. Kuv xaiv ib qho uas muaj 800mA tso tawm, tab sis txhua yam tshaj 500mA yuav tsum npog feem ntau cov phiaj xwm hluav taws xob. 1 Cov Ntawv Me Me - 276-148Qhov pawg thawj coj tshwj xeeb no yog qhov loj me rau lub Circuit Court no, thiab kuv kev teeb tsa yog raws nws. Nov yog daim ntawv ua kom zoo nkauj, tab sis yog tias koj xav ua koj tus kheej PCB, xav tias siv lub EagleCAD txuas nrog los ua cov txheej txheem tsim koj tus kheej. 1 Cov Dej Kub Kub - 276-1368A kev tiv thaiv zoo. Tus tswj hwm tau tsim kev tiv thaiv los tiv thaiv nws los ntawm kev hlawv nws tus kheej, tab sis nws ua li ntawd los ntawm kev txwv tam sim no. Yog tias koj tsis muaj lub dab cua sov, koj yuav pom tias koj muaj cov zis tam sim no tsawg dua li qhov koj xav tau. Ib qho ntawm cov hlau yuav ua haujlwm ntev li ntev tau koj tuaj yeem txuas nws hlau-rau-hlau ntawm lub tab. Txawm tias tus nab kuab loj loj yuav muab cov cua sov tsim tawm kom zoo.

Kauj Ruam 2: Cov Cuab Yeej

Cov no yog cov cuab yeej txheej txheem rau sib sau ua ke yuav luag txhua qhov haujlwm hluav taws xob. Tsis yog txhua yam ntawm no yog qhov tsim nyog kiag li, tab sis lawv ua rau txoj haujlwm yooj yim dua. Kev Muag Khoom Hlau Tsis yog rab phom phom. Cov phom phom ua cov khoom siv hluav taws xob ua kua muag ntawm cov yas yaj. Kuv twb pom lawm. Tsis muaj qhov tso dag. MultimeterWire strippersPliersSide-cuttersSolder-suckerNot xav tau yog tias koj tsis xav tias koj yuav ua yuam kev. Qhov me me taub hau taub hau ntswj kom nruj cov ntsia hlau ntawm lub davhlau ya nyob twg. Pab txhais tes Cov no yog cov khoom lom zem uas tuav cov khoom thaum koj nyob nraum soldering. Cov no muaj txiaj ntsig zoo rau txoj hauv kev ntau dua li cov khoom siv hluav taws xob. Nws yuav tsum yog qhov tseem ceeb!

Kauj ruam 3: Breadboard

Breadboarding tsis tas yuav yog koj li kev ntseeg siab yuav ua haujlwm, tab sis nws yog lub tswv yim zoo los ua nws lawm. Yog tias muaj teeb meem tshwm sim tam sim no, koj tuaj yeem kho nws ua ntej nws tau teeb tsa. Nco ntsoov ntsuas qhov ntsuas hluav taws xob kom ntseeg tau tias tsis muaj dab tsi tawm ntawm kab.

Kauj Ruam 4: Qhuav Haum Cov Cheeb Tsam

Koj yuav xav tso txhua yam tawm ntawm daim ntawv ua ntej koj muab nws tso rau. Koj zoo siab txais tos siv kuv qhov kev teeb tsa. Ib qho yog qhov ib txwm muaj thiab ib qho yog thim rov qab yog li koj tuaj yeem pom qhov khoom sib xyaw thaum koj tab tom saib ntawm qhov muag sab. Cov dots dub qhia qhov twg cov pins hla hauv pawg thawj coj saib. Cov kab dub yog cov cim tooj liab. Cov kab liab yog cov choj txuas. Kuv tau txais cov qauv los ntawm runoffgroove.com. At qhov no, koj tseem yuav xav khoov cov tooj liab. Siv cov hlua hluav taws xob los hle tag nrho cov rwb thaiv tsev tawm ntawm cov xov hlau ntev, thiab khoov lawv kom raug qhov ntev. Khoov txhua txoj kab tooj liab tshwj tsis yog cov uas coj mus rau lub dav hlau dav hlau. Cov no tau yooj yim dua ntxiv tom qab tag nrho lwm cov khoom siv tau muab muag.

Kauj Ruam 5: Cov Khoom Solder

Tam sim no koj npaj tau los ua kom cov khoom sib txuas rau. Pib nrog cov cim tooj liab. Tom qab ntawd, tus tiv thaiv, hloov pauv, lub zog, lub tshuab hluav taws xob, lub diodes, thiab thaum kawg tus tswj hwm (hauv qhov kev txiav txim.) Nws yooj yim dua rau solder tus tswj hwm nrog lub dab dej kub twb tau teeb tsa. Ntxiv rau, nws yuav tiv thaiv cov khoom tiv thaiv los ntawm tshav kub ntawm cov hlau phom. Tsis txhob txhuam cov phab ntsa hauv qhov txhab lossis lub davhlau ya nyob twg. Nco ntsoov tias polarity yuav tsum tau muab sau tseg rau cov khoom xws li cov tshuab hluav taws xob (C2) thiab cov ntsuas hluav taws xob. Tsis txhob solder lawv rov qab!

Kauj Ruam 6: Solder Ntau Yam

Tam sim no, muab lub dav hlau tso rau hauv qhov chaw. Tom qab ntawd, muab tshuaj txhuam rau hauv cov cim rau ntawm kab txaij. Nco ntsoov tias cov kab zoo raug hla hla qhov tsis zoo ib sab ntawm nws, yog li koj yuav tsum tso me ntsis rwb thaiv tsev ntawm qhov zoo kom tsis txhob tsim qhov luv luv Circuit Court. Tom qab ntawd, muab cov kab hluav taws xob ntsaws rau ntawm phab ntsa, ua rau pom qhov tsis sib xws. Txiav txhua qhov ntev ua ze rau ntawm cov laug txuas nrog rau sab txiav. Thaum kawg, ua kom tag nrho cov kab laug sab laug txhawm rau txuas cov khoom sib txuas mus rau qhov khoom. Saib xyuas nrog cov khoom siv rhiab heev xws li diodes thiab tus tswj hwm. Cov no yog rhiab rau cua sov.

Kauj Ruam 7: Kev Tswjhwm Zoo

Mus hla txhua qhov kab thiab ua kom ntseeg tau tias koj muaj cov pob qij txha zoo, thiab tias tsis muaj qhov cuam tshuam los ntawm tus choj txuas. Siv lub ntsuas ntsuas ntawm qhov ntsuas tsis kam yog ib txoj hauv kev yooj yim los saib seb cov pob qij txha puas kov.

Kauj Ruam 8: Lub Sijhawm Tseeb

Plug lub phab ntsa-wart rau hauv thiab ntxeev qhov hloov. Yog tias cov pa luam yeeb tawm ntawm qhov ntsuas hluav taws xob, koj tau txais qee yam tsis raug. Yog tias tsis muaj dab tsi tshwm sim, tej zaum yuav zoo rau koj. Nqa koj lub multimeter thiab ntsuas qhov hluav taws xob. Xyuas kom tseeb tias lub hwj chim tuaj yeem hloov kho qhov hluav taws xob. Yog tias txhua yam tshuaj xyuas, ua kev zoo siab! Koj npaj tau pib lub neej ntev ntawm kev siv hluav taws xob.

Kauj Ruam 9: Muaj peev xwm txhim kho thiab hloov kho

Qhov Circuit Court no hloov pauv tau zoo heev. Koj tuaj yeem hloov kho qhov tseem ceeb ntawm R1 thiab R2 kom haum rau txhua yam khoom koj muaj ntawm tes. Kuv tau tsim kuv tus kheej Circuit Court siv 0 - 4K lauj kaub uas kuv muaj ntawm tes. Yog tias koj xav hloov cov resistors, siv cov qauv hauv qab no:

VOUT = 1.25 * (1 + (R2/R1))Tus nqi R1 yuav tsum nyob nruab nrab ntawm 10 ohms thiab 1000 ohms. Txhua yam siab dua thiab tus tswj hluav taws xob yuav tsis coj tus yam ntxwv. Yog tias koj txiav txim siab hloov pauv rau hauv Circuit Court, koj yuav tsum xa mus rau cov ntawv teev npe kom paub meej ntxiv. Qhov chaw no yog lwm qhov siv zoo rau kev siv LM317T. Ideas los ntawm cov lus-Koj tuaj yeem muab tag nrho cov kab hluav taws xob tso rau hauv lub thawv yas ua haujlwm. Qhov ntawd yuav tiv thaiv sab nraub qaum ntawm pawg thawj coj saib kom luv yog tias nws tau ntsib nrog cov cuab yeej hlau. -Koj tuaj yeem yuav lub ntsuas cua uas yuav siv tsuas yog kho qhov tso zis. Txiav tawm qhov kev sojntsuam thiab muab cov xaim txuas ncaj qha rau cov khoom siv rau kev daws teeb meem tas mus li. Yog tias lub ntsuas ntsuas tau hloov pauv mus los, koj tuaj yeem yuav cov khoom siv ntxiv rau siv nrog lwm qhov haujlwm.
