2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Cov ntawv qhia no yuav qhia yuav siv MT3608 txhawb kev hloov pauv kom muaj zog li cov cuab yeej xav tau qhov sib txawv li cas. Peb yuav qhia qhov twg yog hom roj teeb zoo tshaj plaws los siv nrog lub hloov pauv thiab yuav ua li cas thiaj tau txais ntau dua li ib qho tawm los ntawm lub hloov pauv.

Peb yuav piav qhia vim li cas peb tau xaiv tus hloov pauv no thiab peb tuaj yeem siv cov haujlwm zoo li cas.

Tsuas yog ntawv me me ua ntej peb pib: Thaum ua haujlwm nrog cov neeg hlau thiab khoom siv hluav taws xob thov tsis txhob saib qhov tseem ceeb ntawm kev faib hluav taws xob.

Khoom siv:

• MT3608 DC-DC Hloov
• 4.8 Ni-MH Roj Teeb Pob
• Arduino Ib
• Jumper Hlau
• 2S Li-Po lossis Li-Ion Roj teeb
• 2A Fuse ib

Kauj ruam 1: Pinout Txheej txheem cej luam

Ntawm no koj tuaj yeem pom yuav ua li cas MT3608 module zoo li. Koj tuaj yeem pom tias MT3608 yog IC, thiab tus qauv yog kev tsim hluav taws xob nyob ib puag ncig IC kom nws ua haujlwm raws li kev hloov pauv hloov tau.

PINOUT rau MT3608 module yog:

IN+ Ntawm no peb txuas cov xaim liab los ntawm roj teeb (lossis lub zog siv), qhov no yog VCC lossis VIN (2V - 24V)

IN- Ntawm no peb txuas cov xaim dub los ntawm roj teeb (lossis lub zog siv), qhov no yog av, GND lossis V-

Tawm+ Ntawm no peb txuas qhov zoo ntawm qhov hluav taws xob faib hluav taws xob lossis cov khoom siv hluav taws xob

OUT- Ntawm no peb txuas hauv av ntawm lub zog faib hluav taws xob lossis cov khoom siv hluav taws xob

Kauj Ruam 2: Kho Cov Khoom Tawm

Qhov no yog lub zog hloov pauv lub ntsiab lus tias nws yuav siv hluav taws xob qis thiab hloov nws mus rau qhov siab dua. Txhawm rau kho qhov hluav taws xob peb yuav tsum ua ob peb kauj ruam.

• Txuas lub hloov pauv nrog lub roj teeb lossis lwm lub zog siv.
• Teem lub multimeter los nyeem qhov hluav taws xob thiab txuas cov zis ntawm lub hloov pauv rau nws. Tam sim no koj tuaj yeem pom qhov hluav taws xob ntawm cov zis.
• Kho lub trimmer (ntawm no 100k Ohm) nrog cov ntsia hlau me me kom txog thaum qhov hluav taws xob tau teeb tsa rau qhov xav tau tso tawm. Xav tias dawb tig lub trimmer hauv ob qho kev qhia kom tau txais kev xav yuav ua haujlwm nrog nws li cas. Qee zaum thaum koj siv lub tshuab hloov pauv thawj zaug koj yuav tsum tig lub hau ntswj taub hau 5-10 lub voj voos kom nws ua haujlwm. Ua si nrog nws kom txog thaum koj tau txais qhov kev xav.
• Txuas lub cuab yeej/tus qauv uas koj xav kom siv hluav taws xob ntau dua.

Kauj Ruam 3: Kev Ntsuas Tam Sim No

Qhov ntsuas tam sim no tsis tu ncua ntawm IC MT3608 yog 2 A, nti zoo nkauj me me yog li nws nyuaj rau faib cov cua sov. Peb ib txwm tuaj yeem ntxiv tsawg kawg ntawm lub dab dej kub tab sis tsis txhob cia siab tias nws yuav muaj qhov ntsuas tam sim no ntau dua 2 A.

Kauj Ruam 4: Kev Tiv Thaiv Tam Sim No

Lwm qhov uas yuav tsum tau hais thaum ua haujlwm nrog cov qauv siv hluav taws xob zoo li hloov pauv yog tias lawv yuav hlawv tawm yog tias tam sim no mus siab dhau. Kuv ntseeg tias koj twb nkag siab tias los ntawm cov kauj ruam saum toj no, tab sis yuav tiv thaiv IC li cas los ntawm qhov siab tam sim no?

Ntawm no peb xav qhia lwm qhov kev tivthaiv: Fuse. Hauv qhov xwm txheej tshwj xeeb no peb hloov pauv xav tau kev tiv thaiv los ntawm 2 Amps. Yog li peb yuav siv 2 Amp fuse thiab xaim nws raws li daim duab hauv qab no. Qhov no yuav muab kev tiv thaiv tsim nyog rau peb IC.

Sab Hauv Fuse muaj cov xaim nyias ua los ntawm cov khoom uas yaj hauv qhov kub tsis txias, cov tuab ntawm cov xaim tau ua tib zoo kho thaum tsim khoom kom xaim yuav tawg (lossis tsis muag) yog tias tam sim no mus saum 2 Amps. Qhov no yuav nres qhov dej ntws tam sim no thiab lub siab tam sim no yuav tsis tuaj yeem hloov pauv. Tau kawg qhov no txhais tau tias peb yuav tau hloov Fuse (vim tias nws tau yaj tam sim no) thiab kho qhov Circuit Court uas tau sim kos ntau dhau tam sim no. Yog tias koj xav paub ntau ntxiv txog cov fuses thov xa mus rau peb cov ntawv qhia rau lawv thaum peb tso tawm.

Kauj Ruam 5: Hwjchim 5V Tus Tswj thiab 3.3V Tus Tswj Hluav Taws Xob Los Ntawm Ib Qhov Chaw

Nov yog qhov piv txwv uas suav nrog txhua yam hais los saum no. Peb yuav suav nrog txhua yam nrog cov kauj ruam txuas:

• Txuas lub roj teeb Ni-MH nrog lub hloov pauv.
• Kho qhov hluav taws xob rau 5V nrog lub ntsuas hluav taws xob txuas nrog ntawm cov zis.
• Txuas hauv av thiab VCC los ntawm lub roj teeb nrog lub hloov pauv cov khoom siv txuas.
• Txuas qhov txiaj ntsig zoo nrog 5V ntawm Arduino thiab dhau los ntawm lub khob cij.
• Txuas cov txiaj ntsig tsis zoo nrog GND ntawm Arduino.
• Txhawm rau pom cov ntsiab lus hais txog qhov thaiv ntawm LM317 Voltage Regulator thov mus saib ntu ntawd.

Kauj Ruam 6: Xaus

Peb xav los tham txog yam peb tau qhia ntawm no.

• Siv MT3608 los hloov qhov hluav taws xob los ntawm qis (2 - 25) rau siab
• Ib txwm siv Multimeter los tshuaj xyuas qhov ntsuas hluav taws xob ntawm qhov tso tawm ua ntej txuas rau lwm yam khoom siv/qauv
• Siv MT3608 rau 2 Amps lossis qis dua
• Siv 2 Amp Fuse los tiv thaiv MT3608 yog tias koj tab tom tsav lub zog thiab kos cov dej ntws uas tsis tuaj yeem kwv yees tau
• Los ntawm kev siv cov hloov pauv koj tab tom muab cov hluav taws xob ruaj khov rau koj cov khoom siv hluav taws xob uas muaj txaus uas koj tuaj yeem siv los ntseeg tau tswj lub cav, ua li no koj yuav tsis muaj tus cwj pwm txo nrog cov roj teeb hluav taws xob poob thaum lub sijhawm
