Cov lus qhia no yuav qhia koj yuav ua li cas thiaj ua Arduino 7 ntu ntu.
txawm tias qhov tseeb nqus!
yog li kuv tsuas yog ua qhov no rau lub cajmeem thiab kev lom zem.
yog tias koj xav ua lub moos loj koj tuaj yeem siv rtc module uas yuav khaws cov ntaub ntawv teev tseg.
koj tuaj yeem siv premade 4 xya-ntu tso saib yog tias koj tsis xis nyob nrog txoj hlua yooj yim uas tuaj yeem txo qis txoj hauv kev xoob kev sib txuas thiab tso tawm tsis raug.
ib lub laub khawm yog kom nce teev thiab lwm tus yog kom nce feeb los ntawm ib qho.
Khoom siv
Cov qhob cij
Arduino (kuv nano)
4 xya-ntu tso saib
2 laub khawm
2 ua led
4 ib-Kohm resistor
ib qho tam sim no txwv resistor (220ohm)
qee qhov txuas xov hlau
Kauj Ruam 1: Multiplexing 4 Xya-ntu Zaub
txuas txhua tus pin sib xws ntawm txhua 7-seg rau ib leeg kom sib npaug ntawm cov zaub hauv qhov kev txiav txim muab hauv cov duab saum toj no.
Kauj Ruam 2: Txuas 7 Segment Display rau Arduino
Txuas txhua lub davhlau ya nyob twg ntawm 7-ntu tso saib rau tus lej digital ntawm Arduino raws li cov phiaj xwm no.
Ib tus lej pin 2
B - tus pin 3
C -tus lej pin 4
D -tus pin 5
E - tus pin 6
F -tus pin 7
G -tus pin 8
DP -tus lej pin 9.
Txuas txhua tus pin rau digital pin ntawm Arduino los ntawm 1K ohm resistor
D1 - tus lej pin 10
D2 - tus lej pin 11
D3 -digital tus pin 12
D4 - tus pin 13
Kauj Ruam 3: Txuas Ob Sab Coj thiab Kho Khawm
Hauv av ib lub dav hlau ntawm laub-khawm thiab cathode ntawm LED.
Txuas lub davhlau ya nyob twg mus rau A0 thiab A1 feem.
LED anode rau A3.
Kauj ruam 4: Code
Rub tawm 7 ntu tso saib lub tsev qiv ntawv ua ntej los ntawm qhov txuas hauv qab no los ntawm Github thiab rho tawm nws mus rau hauv Arduino ide cov tsev qiv ntawv nplaub tshev
xya-ntu tsev qiv ntawv
upload code rau koj Arduino
koj tuaj yeem hloov txoj cai raws li koj tus kheej.

Mechanical Seven Segment Display Clock: 7 Cov Kauj Ruam (nrog Duab)
Mechanical Seven Segment Display Clock: Ob peb lub hlis dhau los Kuv tau tsim ob tus lej 7 tshuab ntu uas kuv tau hloov mus rau lub sijhawm suav suav. Nws tau tawm los zoo heev thiab muaj coob tus neeg pom tias ua ob npaug ntawm cov zaub kom ua lub moos. Qhov teeb meem yog tias kuv twb tau khiav lawm
7 Segment Clock - Cov Ntawv Luam Me Me: 9 Kauj Ruam (nrog Duab)
7 Segment Clock - Cov Tshuab Luam Ntawv Me Me: Tseem muaj lwm 7 Segment Clock. xDAl Txawm hais tias kuv yuav tsum hais tias nws tsis zoo li vwm thaum saib kuv li Instructables profile. Tej zaum nws yuav ua rau khaus ntau dua thaum lub sijhawm koj tau saib ntawm kuv qhov profile thoob plaws.Yog vim li cas kuv thiaj li tsis thab lwm qhov
7 Segment Clock Version 2: 4 Cov Kauj Ruam
7 Segment Clock Version 2: Nyob Zoo! Tom qab thov los ntawm Instructables cov neeg siv hais txog kev muaj 12h hom ntawv, kuv tau ua kom zoo los hloov pauv nyiaj txiag rau thawj qhov haujlwm. yog li kuv ua nws possibility
7 SEGMENT DIGITAL CLOCK THERMOMETER: 6 Kauj Ruam
7 SEGMENT DIGITAL CLOCK THERMOMETER: Nws ua haujlwm los ntawm 12v 500mA adapter.Qhov siab qhov siab yog 57 hli thiab nws qhia cov ntaub ntawv teev txhua teev nyob rau 24 teev. ntawm lub cim xeeb
Sib dhos "Wise Clock 2" (Arduino-based Alarm Clock With Many of Extra Features): 6 Kauj Ruam
