Ib tus lej loj, ua haujlwm tau zoo Arduino Nano moos

Kauj Ruam 1: Cov lus piav qhia

Lwm qhov ntawm cov teev tsis txawv txav, lub sijhawm no ua nrog kev pab ntawm lub tshuab luam ntawv 3D.

Kauj ruam 2: Cov ntaub ntawv

Txhawm rau tsim txoj haujlwm no peb xav tau cov hauv qab no:

- Arduino Nano microcontroller board

- DS3231 Lub Sijhawm Sijhawm Sijhawm Sijhawm

- SMD5050 Coj sawb

- 8x 2N2222 lossis zoo ib yam li Transistors

8 x 560 Ohm Resistors

- 2 X khawm

- Led diode thiab 220 Ohm Resistor

Kauj Ruam 3: Lub Tsev

Kuv tau txais kev tshoov siab kom ua lub moos no los ntawm:

8bitmicro.blogspot.com/2012/02/project-clock-two-single-digit-clock.html, tab sis tam sim no nrog DIY 7 ntu ntu ua los siv lub tshuab luam ntawv 3D thiab 5050 LED sawb. Cov cai tau hloov kho rau DS3231 lub sijhawm tiag tiag uas tseem yog qhov pheej yig tab sis raug ntau dua li DS1307. Cov kab hluav taws xob LED tuaj yeem txiav ntawm txhua qhov diode thib peb hauv koob. Hauv qhov no peb yuav tsum txiav nws ntawm txhua qhov diode thib ob. Rau lub hom phiaj no tau hloov kho me me uas koj tuaj yeem pom hauv video. Txhua ntu ntawm kab txaij tau tsav los ntawm 2N2222 lossis zoo ib yam li lub zog qis transistor.

Kauj Ruam 4: Shematic, Code thiab 3D Printing Parts

Txog sijhawm teeb tsa peb siv ob lub khawm. Lawv tau txuas nrog digital pins yim thiab cuaj (nrog 10k rub-down resistors). LED tso saib ntu a ~ g txuas nrog Arduino digital pins 0 ~ 6 feem. Cov lej zauv yog txuas nrog tus pin mem tes tso tawm ntawm DS3231 - uas yuav raug teeb tsa rau 1Hz tso tawm kom muaj qhov zoo ntsais ntsais ntsais LED los qhia lub moos tseem muaj sia thiab zoo.

Arduino thiab lwm yam khoom siv hluav taws xob tau nyob hauv lub thawv yooj yim nrog 7 ntu ntu tso saib saum toj no. Hauv qab no yog qhov txuas uas koj tuaj yeem rub cov cai thiab.stl cov ntaub ntawv rau 3D Luam Ntawv.
