1 x DS18B20 ntsuas kub

1 x Arduino uno board

1 x LCD nrog I2C

1 4.7k tiv

txhua yam npaj tau hauv is taws nem, txoj haujlwm no raug nqi kuv ib ncig $ 20

qee cov xov hlau jumper

Kauj Ruam 2: Txuas DS18B20

Kev txuas ntawm DS18B20
Kev txuas ntawm DS18B20

Cov hlau liab lossis VCC mus rau 5v ntawm Arduino

Cov xaim dub lossis av mus rau hauv av ntawm Arduino

Cov xaim daj lossis Cov Ntaub Ntawv mus rau tus pin 2 (lossis tus pin twg koj tau xaiv)

yuav tsum muaj 4.7k resistor ua ke nrog Cov Ntaub Ntawv xov hlau thiab VCC xaim raws li qhia hauv daim duab.

Kauj Ruam 3: Txuas I2C LCD

Kev thaiv ntawm I2C LCD
Kev thaiv ntawm I2C LCD

GND tus pin rau hauv av ntawm Arduino

VCC tus pin rau 5v ntawm Arduino

SDA tus pin rau A4 ntawm Arduino

SCL tus pin rau A5 ntawm arduino

Txoj Cai

Muaj cov ntawv luam tawm hauv kab hauv kab ntawv los pab daws teeb meem. Nws tsis tas yuav ua haujlwm

Tsis tas li kuv muaj lub heck ntawm lub sijhawm nrhiav qhov tseeb thiab ua haujlwm tsev qiv ntawv rau LCD. Nws txuas nrog ua tej yam yooj yim rau koj.
