Nyob Zoo Cov Neeg, Hauv Cov Lus Qhia no koj yuav pom yuav ua li cas txuas i2c lcd zaub rau arduino thiab yuav ua li cas luam tawm ntawm lcd zaub.

Ua ntej yuav pib qhov kev qhia no koj yuav tsum paub luv luv txog i2c kev sib txuas lus.

Txhua lub npav I2C muaj ob lub cim: SCL thiab SDA. SCL yog lub moos teeb liab, thiab SDA yog cov ntaub ntawv teeb liab. Lub moos teeb liab ib txwm tsim los ntawm tus tswv tsheb npav tam sim no; qee cov cuab yeej qhev yuav yuam kom lub moos qis ntawm qee lub sijhawm kom tus tswv xa cov ntaub ntawv ntau ntxiv (lossis xav tau sijhawm ntau los npaj cov ntaub ntawv ua ntej tus tswv npaj rau teev nws tawm). Qhov no hu ua "ncab moos" thiab tau piav qhia nyob rau nplooj ntawv txheej txheem.

Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau

Arduino Uno:

I2C LCD Zaub:

Kauj ruam 2: Kev sib hloov

I2C Board of LCD Arduino

GND GND

VCC 5 VV

SDA AW 4

SWB A5

Kauj ruam 3: Code

Peb yuav tsum xav kom suav nrog ob lub tsev qiv ntawv, txhawm rau ua haujlwm txoj cai txuas nrog.

Rub tawm cov tsev qiv ntawv los ntawm cov ntawv txuas hauv LCD.

Cov haujlwm yooj yim peb siv hauv cov cai

lcd.begin (16, 2); // Txhais 16 kab thiab 2 kab ntawm lcd zaub

lcd.backlight (); // Txhawm rau Hwj chim ON /OFF lub teeb nraub qaum

lcd.setCursor (0, 0); // Txhais qhov positon sau los ntawm thawj kab, thawj kab ntawv.

lcd.setCursor (0, 1); // Txhais qhov positon sau los ntawm kab thib ob, thawj kab ntawv.

lcd.print ("sau ntawm no kom luam tawm"); // Koj tuaj yeem sau 16 Tus Cim rau ib kab hauv kab lus.

lcd.clear (); // Ntxuav qhov screen

Kauj Ruam 4: Tso Tawm

Cov txiaj ntsig txuas nrog tau ua tiav raws li cov cai txuas saum toj no.
