Video: Arduino LCD Master Clock: 10 Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Lub moos no tau tsim los ua lub moos sawv ib leeg lossis ua lub moos tseem ceeb los tsav moos qhev thiab nqa tau nrog roj teeb thaub qab. Saib lub moos lub vev xaib kom paub meej ntxiv LCD Master Clock Home Page
Hloov tshiab- Tsis siv neeg lub caij ntuj sov ua ntej thiab Lub Caij Nyoog Retard khawm ntxiv rau qhov siv Udo Klein DCF77 lub tsev qiv ntawv. Nias lub pob ib zaug txhawm rau saib lub moos ua ntej lossis rov qab 1 teev
Lub moos no siv Arduino 328 Microprocessor los txiav txim Lub Sijhawm los ntawm DCF77 "Atomic" Clock hauv Mainflingen ze Frankfurt Germany. Lub sijhawm tau tshwm ntawm qhov hloov pauv lub cev pob txha uas tswj los ntawm lub microcontroller thiab Blue 4x20 LCD zaub. Lub moos pulses los tsav tus lej qhev raug saib xyuas ntawm LED vaj huam sib luag. 3 x 1.5volt AA hlwb muab roj teeb thaub qab thaum txuas los ntawm lub hauv paus. Lub rooj tsavxwm tseem ceeb muaj USB rau UART txuas yog li lub moos software tuaj yeem hloov kho los ntawm PC lossis txawm tias Mac. Cov lej lej tau suav nrog rau kev saib xyuas ntawm USB tab sis tau hais tawm.
Hloov kho cov lej suav nrog kom ua haujlwm Udo Klein DCF77 lub tsev qiv ntawv. Udo Klein's DCF77 lub tsev qiv ntawv khaws lub moos ua ke thiab ua kom lub sijhawm zoo txawm tias muaj suab nrov ntau ntawm qhov tau txais DCF77 teeb liab. DCF77 lub tsev qiv ntawv tseem pheej txuas ntxiv "Pib Tunes" lub quartz siv lead ua yog li hauv qhov xwm txheej tsis tshua muaj lub teeb liab tsis tuaj yeem txiav txim siab lub moos tseem raug nyob hauv 1 vib nas this ntau hnub. Qhov no tseem ceeb heev rau Tus Xib Hwb uas tsav 1 tus qhev ib pliag raws li vib nas this drift yuav ua rau cov moos qhev poob kev sib cuag nrog tus Xib Hwb Sijhawm.
Txoj cai rau lub tsev qiv ntawv txheem tseem suav nrog yog tias koj muaj lub cim DCF77 zoo heev.
Kauj Ruam 1: Ua Case
Cov ntaub ntawv yog hloov kho BORRBY tswm ciab teeb los ntawm Ikea.
Cov ntaub ntawv raug hloov kho raws li hauv qab no:
1 Laum tawm qhov txuas uas tuav saum rau lub thav duab loj
2 Tshem tawm sab saud
3 Txiav tawm qhov cua tshuab hniav nyiaj hniav kub rau sab pem hauv ntej kom ua qhov chaw rau cov duab LCD
4 Txiav ntoo lossis ntawv hlau txhawm rau sau cov qhov cua qhov cua uas tseem nyob
5 Sau qhov khoob nruab nrab ntawm lub hauv paus thiab thav duab nrog cov kab ntoo. Lub hauv paus Circuit Court board nyob ntawm cov ntoo no. Tshem tawm tswm ciab los ntawm lub hauv paus thiab ntxiv plaub taw.
6 Ntxiv lub plywood tshiab sab saum toj thiab kho nrog hinges nraub qaum. Kev so yuav tsum tau txiav rau sab saum toj txhawm rau txhawm rau sab saum toj ntawm LCD lub rooj tsav xwm uas tawm los ntawm lub hauv paus.
7 Ntxiv tus tes thiab txiav lub qhov hauv paus rau cov hlua.
8 Kho LCD zaub hauv kev txiav tawm
9 Txhim Kho Lub Cev Pob Zeb Tsiv txav los ntawm kev tshem tawm saum toj
10 Xaub hauv PCB thiab LED zaub vaj huam sib luag
Kauj Ruam 2: LCD Zaub Siv Udo Klein's DCF77 Library
"thauj khoom =" tub nkeeg "Cov vis dis aus qhia lub moos ua haujlwm thiab chiming los ntawm 23:59:55 txog 00:00:32
Chimes yog los ntawm cov kab hluav taws xob sib cais tab sis tuaj yeem ua hluav taws xob lossis kuaj los ntawm lub suab suab.
