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

Peb txhua tus xav tau lub moos yog li vim li cas ho tsis ua koj tus kheej hauv phau ntawv qhia no Kuv yuav qhia koj yuav ua li cas thiaj ua tau lub Caij Nyoog Precision thaum koj teeb tsa yuav cia li taug qab lub sijhawm tam sim no hauv keeb kwm yav dhau los ntawm txhua yam. Thaum tseem tsuas xav tau cov khoom siv me me thiab xoom solderings.

Khoom siv

Ua ntej, koj yuav xav tau Arduino tab sis ib qho Arduino yuav ua haujlwm

Tom ntej no, koj yuav xav tau ntau yam ntawm cov xov hluav taws xob dav dav.

2 12mm Sparkfun Pushbutton Hloov

Ib txwm Breadboard

thiab LCD 1602 16 tus pin zaub

Kauj ruam 1: Kev thaiv kab

Txhawm rau lub moos no ua haujlwm koj yuav tsum tau xaim qhov no tshwj xeeb lossis lwm yam koj yuav tau txais cov lej ntawm cov lej tsis raug ntawm lub vijtsam ntau dua li lub sijhawm.

Kauj ruam 2: Txoj Cai

Txij li thaum peb tsis siv RTC peb cov cai yuav mus ntev me ntsis tab sis ua tsaug kuv tau ua txhua yam haujlwm nyuaj rau koj thiab muab rau ntawm no.

Tsuas yog Luam thiab Paste qhov no rau hauv Arduino IDE lossis lub vev xaib Editor.

Kauj Ruam 3: Schematic (Qhov No Tsis Yog Ib Kauj Ruam tiag)

Yog leej twg nyeem qhov no yog thev naus laus zis nerd ntawm no kuj yog cov txheej txheem koj tuaj yeem saib nws mus vwm.

Txaus siab thiab muaj kev lom zem thiab feem ntau ntawm txhua yam nyob tshiab.
