2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Txoj Haujlwm no yog Ua los rau lub hom phiaj uas nws nyiam ua los ua Yam Sib Txawv Los Ntawm Diy Cov Haujlwm.

Nov yog ib qho ntawm Diy Project Digital Clock. Lub Sij Hawm Digital Muaj Qhov Sib Txawv Zoo Li Nws Qhia Lub Sijhawm, Hnub Tim, Tswb, Kub, Kev Hloov Pauv Sib txawv hauv LED s soldered hauv Rounded Shape; Ib yam li nws tuaj yeem txo nws qhov Kev Nyuaj Siab Raws Li Kev Pom Zoo Ib puag ncig.

Khoom siv

Lub Sijhawm Digital no muaj nrog Cov Khoom Online nrog Txhua Tus Txheej Txheem Hauv Cov Khoom.

Cov Khoom Siv Hauv Digital: Cov Khoom Siv Clock

Xws li IC: IAP15W413AS*1

Sijhawm Chip: DS1302*1

Kuj (R1 ~ R15)*15

Thermistor (RT1)*1

Cov khoom siv hluav taws xob (C4, C5)*2

Monolithic capacitor (C2, C3)*2

Crystal oscillator (Y1)*2

Cov yuam sij (S1, S2)*2

LED (D1 ~ D60)*60

Roj teeb rooj (BT1)*1

Electrolytic capacitor (C1)*1

Buzzer (LS1)*1

Segment Display (DS1)*1

USB Mini: Thaiv USB (USB1)

Cov ntsiab lus no yuav tsum tau sau tseg tias tus ncej zoo thiab tsis zoo ntawm lub rooj tsav xwm hauv Circuit Court yuav tsum raug sau tseg. Cov ntsiab lus no yuav tsum tau sau tseg nyob rau tib qho kev taw qhia raws li lub rooj tsav xwm hauv Circuit Court. 3, Kev siv vuam zoo LED, lub raj digital, Thermistor, thiab lwm yam khoom siv ntawm Cov Leeg Nyob tom qab. 4, LED muaj ob xim, tsawg dua cov xim vuam vias nyob rau hauv coob ntawm txoj haujlwm sib xws, thiab qhov seem ntawm qhov chaw ntawm tus lej ntau dua ib xim. 5, U2, C4, C5, Y1, BT1 yuav tsum tau Soldered ua ntej lub raj digital, xyuam xim rau cov ntsiab lus ntawm cov raj digital. 6, Lub zog ua haujlwm ntawm cov khoom siv yog 5V, lub roj teeb nyob tom qab tsuas yog siv rau lub zog txuag lub sijhawm.

Kauj Ruam 1: Nkag Siab Kev Sib Txuas Circuit Circuit

Saum Ntuj Ceeb Tsheej Daim Duab Daim Duab yog rau Lub Hom Phiaj Siv, Kom nkag siab zoo Qhov twg yog tus tswj hwm ICs tau siv thiab Qhov Kev Sib Txuas twg yog qhov hauv LED s, Cov Tiv Thaiv, Tus Tswj, RTC (DS1302), USB thiab tag nrho lwm yam khoom siv.

Peb yuav tsum ua kom ntseeg tau tias Cov Cuam Tshuam Yuav Cuam Tshuam Qhov Sab Ntawm PCB, thiab tseem saib xyuas Txog Kev Siv Txhua Lub Cheebtsam hauv Tus Cwj Pwm Zoo Yog li ntawd tsis muaj ib lub davhlau ya nyob twg ntawm Cheeb Tsam tau teeb tsa; Vim tias Qhov No Ua Rau Cov Neeg Tswj thiab lwm yam ICs puas tsuaj.

Kauj Ruam 2: Cov Cheebtsam Cheeb Tsam

Cov kauj ruam no tseem ceeb heev hauv Txoj Haujlwm. Ua ntej peb yuav Pib Soldering los ntawm LED s, Cov LED s yuav tau Solder nyob rau hauv ntu uas tau muab hauv thawj daim duab Nws txhais tau tias ntawm Txhua Lub Sijhawm Teev yuav tsum muaj Blue Led thiab txhua qhov yuav sawv rau Red Led. Cov no yog 3 mm LED s, yog li peb yuav tsum paub tseeb thaum Solder txhua lub davhlau ya nyob twg. Then Solder 4 Digit Segment Display Unit ntawm (DS1) Sau rau ntawm PCB, nyob rau sab saud ntawm Zaub muaj ob qhov rau Thermistor thiab LDR Solder Lawv kom raug ntawm qhov Chaw.

Tam sim no, Sab ntawd Ua tiav.

Tig PCB, Koj yuav pom Ntau Lub Thawv Nyob ntawm Txhua txoj haujlwm rau Cov Khoom Siv Hluav Taws Xob. Tam sim no Thawj Tus Kws Lij Choj Hauv paus ntawm ICs Muaj Feem ntau ob qhov rau qhov uas yog 1.) 28 tus lej Base 2.) 8 tus lej Base Tus ob yog Nyob Dhau ntawm PCB. Solder Lub Hauv Paus, Tsis Txhob Txuas IC ntawm lawv Lub Hauv Paus Tam Sim No, txuas nws tom qab Txhua Cheeb Tsam yuav solder kom raug.

Tam sim no Siv Cov Cheeb Tsam Me Me Zoo li Cov Tiv Thaiv thiab Cov Capacitors, Muab tag nrho cov Cheeb Tsam ntawm lawv Qhov Chaw.

Solder Battery Base thiab USB Port.

Tom qab ntawd Ua Kom Zoo Tag Nrho Cov Khoom Siv Hluav Taws Xob tau zoo tshaj plaws thiab txhua yam khoom siv tau raug txuas nrog PCB.

Kauj Ruam 3: Ua haujlwm ntawm ICs

Qhov no kuj yog ib feem tseem ceeb rau kev ua ib qhov Haujlwm

Txoj Haujlwm no Muaj Feem Ntau 2 ICs

1.) Tus Tswj IC: IAP15W413AS

Tus IC no yog Tus Tswj IC uas Tswj Txhua Yam Nws Tswj Kev Teeb ntawm Lub Teeb, Qhov Muaj Nqis Los Ntawm Thermistor thiab LDR. Cov Zais Tawm ntawm Zaub ntawm Zaub, Uas Cov Tswv Yim yuav muab rau Moos; Hom no ntawm txhua yam Nws tuaj yeem ua tau.

2.) Sijhawm Chip: DS1302

Nov yog Lub Sijhawm Chip uas yog Muab Lub Sijhawm Tus Nqi rau Tus Tswj Xyuas los Zaub. Nws yog On Chip RTC uas tuaj yeem Tswj Lub Sijhawm Teeb, Vim tias muaj Cov Roj Teeb ntawm 3v & Crystal los Ua Lub Sijhawm Txawm tias tom qab Lub Sijhawm Tsis Siv. Lub Sijhawm Sab Hauv ib txwm nyob vim yog Lub Hauv Paus.

Kauj ruam 4: Sib dhos

Muaj Cov Ntaub Ntawv Acrylic muab nrog Cov Khoom.

Tag nrho cov Acrylics tau npog nrog yas npog. peb yuav tsum tshem daim npog ntawd thaum sib dhos;

Cov PCB muaj Plaub Hloov Txiav Ib puag ncig nws.we yuav tsum muab cov ntsia hlau uas tau muab nrog Cov Khoom, zoo li muab rau hauv Duab 3.

Los ntawm Txuas Cov Ntsia Hlau Ob Sab Siv daim ntawv ntawm Ib Sab thiab muab txuas nrog Ceev, thiab tseem Txuas Txuas Sab Me Me Acrylics ib txhij; Tsuas yog Tuav Tus Qauv thiab coj Lub Tsheb Tom Qab Ntawm Txuas nws nrog cov seem ntawm qhov Me Me Acrylic daim thiab ntsia nws ntawm Sab Sab.

Kauj ruam 5: Fais fab Nws

Yuav muaj Mini USB Cable Muab Nrog Cov Khoom, Txuas lub USB Cable rau DC 5v Khoom.

Yog Nws. Koj yuav Ua tiav Nrog Digital Clock.

Ua Tsaug Rau Kev Nyeem Ntawv.

Muab Koj Cov Lus Teb Muaj Nqis.
