2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31
Qhov me me sib cais 5 volt PSU yog qhov zoo tshaj plaws rau cov phiaj xwm phiajcim. Koj tuaj yeem lo nws nruab nrab ntawm kev tawg ntawm cov kab hluav taws xob ntawm koj lub khob cij. Nrog lub jumper hloov koj tuaj yeem muab 5 volt rau tag nrho cov kab hluav taws xob lossis 5 volt ntawm sab xis thiab lub hauv paus nkag ntawm sab laug. Uas yooj yim heev rau cov haujlwm uas xav tau kev tswj hwm qhov hluav taws xob. Piv txwv li stepper lub cev muaj zog tswj Circuit Court; 5 volt rau qib kev xav thiab 12 v rau lub cav lossis rov tswj lossis RGB tswj hwm, thiab lwm yam. Cov PSU me me tuaj yeem muab los ntawm ib qho AC/DC hloov pauv (8-18v). Kuv yog los ntawm Netherlands yog li kuv ua qhov kuv sau tau zoo tshaj plaws no ua lus Askiv! Thiab qhov no yog kuv thawj Phau Ntawv Qhia yog li cov lus lossis lus nug raug txais tos.
Kauj Ruam 1: Qhov Chaw thiab Cov Cuab Yeej
Ib feem ntawm PSU me me yog ib txwm muaj. Kuv tau ua daim duab ntawm nws thiab ntawm no yog cov npe:
1) Voltage Regulator 7805CT (cov ntaub ntawv) 2) 150 Ohm Resistor 3) 3mm LED 4) 100 µF, 25 Volt Electrolytic Capacitor 5) 10 µF, 63 Volt Electrolytic Capacitor 6) 100nF Me Capacitor (daim ntawv lo feem ntau yog 104M, yog xav paub ntxiv ntawm Capacitor xim xim, mus ntawm no) 7) 2-pin Screw Terminal 8) 7 tus pin txuas 9) 1 jumper 10) Ib daim kab txaij 11) Ib co xov hlau (siv cov xov hlau nyuaj uas koj tuaj yeem khoov) Saib daim duab rau cov cuab yeej kuv tau siv, lawv kuj zoo nkauj heev.
Kauj ruam 2: Schematic
Cov txheej txheem kuv tau tsim yog lub hauv paus tswj kev ntsuas hluav taws xob nrog rau kev xaiv ntxiv. Raws li koj tuaj yeem pom hauv daim duab muaj ob qhov tawm ntawm tus pin txuas; JP1 thiab JP2. JP1 ib txwm muab qhov tso tawm ntawm 5 volt thiab cov zis ntawm JP2 tuaj yeem xaiv los ntawm JP3: yog tias peb tso lub jumper mus rau tus pin 1, 2 ntawm JP3 cov zis ntawm JP2 yuav zoo ib yam li lub hauv paus nkag thiab yog tias peb tso lub jumper mus rau tus pin 2, 3 ntawm JP3 cov zis ntawm JP2 yuav yog 5 volt. Yog li PSU ua tiav yuav raug ntsaws rau hauv lub khob cij saum toj no so, muab 2 qhov sib txawv lossis ib qho hluav taws xob tso tawm. Kuv tau ua piv txwv ntawm qhov no kom ua kom pom tseeb rau koj. Nco ntsoov tias koj daim ntawv qhia zaub mov kuj tseem yuav tsum tau so hauv kab fais fab. Thiab yog tias nws tsis yog koj tuaj yeem kho PSU kom nws tsuas yog muab 5 volt piv txwv. Tab sis kuv twv nws tseem yog PSU zoo vim nws qhov loj me. Thiab tsis txhob hnov qab muab cov xaim los ntawm cov kab hluav taws xob sab saum toj mus rau kab hauv qab ntawm koj lub rooj noj mov, koj yuav tsum tau ntxiv cov xov hlau nyob ntawm ob sab ntawm lub khob cij, raws li qhia hauv daim duab piv txwv daim duab.
Kauj Ruam 3: Npaj Stripboard
Kuv tau ua piv txwv ntawm lub voj voog mus rau hauv ib daim kab xev, uas ua rau cov ntsiab lus meej heev. Ua ntej koj pom ib daim kab xev, 8 dots hauv kab tooj liab kab rov tav thiab 7 ntsug. Tom qab ntawd koj ua qhov txiav hauv txoj kev tooj liab raws li qhia hauv kab lus. Koj tuaj yeem siv rab riam stanley rau qhov no. Tsuas yog xyuas kom tsis muaj tooj liab kov ib leeg thiab ua kom txiav dav txaus (qee yam zoo li 1mm) kom cov kab laug sab nyias yuav tsis ntws hla qhov txiav thaum siv lub tshuab ua kom sov. Kuv tsis tau thaij duab thaum kuv tab tom tsim kuv lub tsev, thov txim rau qhov ntawd, tab sis kuv ntxiv daim duab hauv qab ntawm kuv qhov ua tiav, tej zaum nws ua kom pom tseeb dua. Nyob zoo! thaum koj ua tiav kev kho cov kab txaij nws yog lub sijhawm mus rau ntawm qhov muag!
Kauj ruam 4: Soldering
Thaum koj pib soldering pib nrog cov xov hlau, tom qab ntawd cov khoom me me thiab tom qab ntawd qhov loj dua. Siv koj txhais tes pab. Thiab yog tias koj pom tias nws nyuaj rau khaws cov khoom nyob rau hauv qhov chaw thim rov qab thaum siv cov laug, khoov qhov kawg ua rau koj cov khoom sib txuas kom clamp me ntsis hauv kab txaij. Yog tias koj pom tias nws nyuaj heev, tsuas yog lo txhua yam khoom siv nrog cov kua nplaum super rau ntawm kab txaij, tab sis tsis txhob lo koj cov ntiv tes koj xav tau cov ntawd! Kuv ntxiv ib daim duab hauv qab ntawm kuv qhov ua tiav kom koj tuaj yeem pom yuav ua li cas kuv muab nws tso rau. Yog li tam sim no siv nws tag nrho ua ke!
Kauj ruam 5: Xeem thiab Ua tiav
Muab tus PSU me me tso rau hauv koj daim ntawv tais. Txuas lub hwj huam hluav taws xob mus rau hauv lub dav hlau ntsia hlau thiab ntsaws rau hauv lub multimeter rau hauv cov kab hluav taws xob. Kuv vam tias koj tau ua nws zoo thiab tam sim no muaj koj tus kheej zoo me me PSU! Kuv vam tias koj tau txaus siab rau kuv cov lus qhia. Yog tias koj tau txais cov lus pom lossis lus nug, xa kuv cov lus lossis tawm lus teb.
