Txoj haujlwm no yog ib feem ntawm qhov loj dua tab sis nws tuaj yeem yog qhov haujlwm ib leeg. Nws yog lub moos nrog ob lub nyees khawm rau teeb lub sijhawm thiab hnub tim.
Nws tsis zoo li ntawm daim ntawv qhia zaub mov nrog txhua cov xov hlau tab sis nws ua haujlwm thiab nws tuaj yeem yooj yim dua los ntawm kev siv I2C zaub, tab sis kuv yuav npog qhov kev kawm yav tom ntej.
Hom kev ua haujlwm yog yooj yim heev, koj muaj ob lub nyees khawm, thawj qhov, txuas rau tus pin 8 ntawm arduino tau siv los xaiv qhov ntsuas (hnub, teev feeb…) thiab thaum kawg txhawm rau txuag hnub tshiab. Khawm thib ob, uas txuas nrog tus pin 9 ntawm arduino, yog siv los ua kom qhov kev ntsuas ntsuas tau xaiv thiab thaum kawg tso tseg cov ntaub ntawv koj nyuam qhuav nkag (tsis khaws) yog tias koj tsis txaus siab rau nws.
Kauj Ruam 1: Qhov Yuav Tsum Tau:
1. Arduino UNO R3 lossis pawg thawj coj saib tau
2. DS3231 RTC (Lub Sijhawm Tiag) module
3. CR2032 roj teeb, yog tus qauv tsis tuaj nrog ib qho
4. LCD 1602 zaub
5. 50K ohm kuj sib txawv resistor rau kho qhov sib txawv ntawm 1602 LCD
6. 2 lub nyees khawm rau kev hloov kho hnub thiab sijhawm
7. Ob 10K ohm resistors rau khawm pins pulldown
8. Jumper hlau rau txuas cov khoom
9. Cov qhob cij
Kauj ruam 2: Sib sau ua ke
Txij li kuv paub tseeb tias koj tsis tuaj yeem ua qhov txuas raws li thawj daim duab ntawm qhov haujlwm, ntawm no yog cov phiaj xwm rau nws.
Kauj Ruam 3: Sau Txoj Cai:
Koj tuaj yeem pom cov cai rau txoj haujlwm no ntawm no, hauv cov ntawv txuas nrog. Xav tias dawb los hloov nws kom haum rau koj cov kev xav tau. Cov cai tau piav qhia hauv cov ntawv.ino. Cov lus pom zoo txais tos.
Kuj lub tsev qiv ntawv kuv siv tau txuas nrog. Lwm lub tsev qiv ntawv ntawm DS3231 yuav tsis ua haujlwm.

Cov Tub Ntxhais Hluav Taws Xob Moos Moos: 9 Kauj Ruam (nrog Duab)
Cov Tub Ntxhais Hluav Taws Xob Moos: Kuv ib txwm tau nyiam los ntawm cov teev tsis txawv txav. Nov yog ib qho ntawm kuv qhov kev tsim kho tshiab kawg uas siv cov tub ntxhais txias txias tus lej los tso saib lub sijhawm. Cov lej tau muab tso rau ntawm ib daim me me ntawm Plexiglas uas muaj cov ntawv nyias nyias laminated rau tom qab
Yuav Ua Li Cas Vaum Thiab Kub Tiag Tiag Cov Ntaub Ntawv Teev Npe Nrog Arduino UNO thiab SD-Card - DHT11 Cov ntaub ntawv-logger Simulation hauv Proteus: 5 Cov Kauj Ruam
Yuav Ua Li Cas Vaum Thiab Kub Tiag Tiag Cov Ntaub Ntawv Teev Npe Nrog Arduino UNO thiab SD-Card | DHT11 Cov ntaub ntawv-logger Simulation hauv Proteus: Taw qhia: nyob zoo, qhov no yog Liono Maker, ntawm no yog YouTube txuas. Peb tab tom tsim txoj haujlwm muaj tswv yim nrog Arduino thiab ua haujlwm ntawm cov kab ke. Cov ntaub ntawv-Logger: Cov ntaub ntawv logger (tseem cov ntaub ntawv-logger lossis cov ntaub ntawv kaw) yog cov cuab yeej siv hluav taws xob uas sau cov ntaub ntawv dhau sijhawm
P10 DMD Zaub Nrog Arduino thiab RTC DS3231: 4 Cov Kauj Ruam (nrog Duab)
P10 DMD Zaub Nrog Arduino thiab RTC DS3231: P10 cov lus qhia yog cov kab ntawm cov teev matrix LEDs. P10 coj yog feem ntau hu ua Dot Matrix Display lossis DMD zaub. Nws yog ua raws cov npe hloov pauv, feem ntau 74595 cov npe hloov pauv tau siv. Lawv tuaj yeem raug rho tawm nrog ntau tus lej ntawm cov laug cam zoo sib xws. A
Kub thiab Vaum Zaub thiab Sau Cov Ntaub Ntawv Nrog Arduino thiab Ua: 13 Kauj Ruam (nrog Duab)
Kub thiab Vaum Zaub thiab Sau Cov Ntaub Ntawv Nrog Arduino thiab Ua: Intro: Qhov no yog Txoj Haujlwm uas siv Arduino board, Sensor (DHT11), lub khoos phis tawj Windows thiab Kev Ua Haujlwm (rub tawm dawb) program los tso saib Kub, Cov ntaub ntawv vaum hauv digital thiab bar kab ntawv, tso tawm lub sijhawm thiab hnub tim thiab suav lub sijhawm suav
Cov Cuab Yeej Siv Hluav Taws Xob thiab Cov Cuam Tshuam Xov: Ua LED Zaub thiab Npuag Hluav Taws Xob uas Rolls Up: 7 Cov Kauj Ruam (nrog Duab)
Cov Cuab Yeej Siv Hluav Taws Xob thiab Cov Cuam Tshuam: Ua kom pom LED thiab Cov Khoom Siv Hluav Taws Xob uas Rolls Up: Ua rau koj tus kheej cov ntaub ua hluav taws xob, xov, kua nplaum, thiab kab xev, thiab siv lawv los ua lub zog ntsuas hluav taws xob, tiv thaiv, hloov pauv, LED cov lus qhia thiab siv hluav taws xob. thiab cov xov hluav taws xob koj tuaj yeem ua cov lus qhia LED thiab cov kab hluav taws xob ntawm ib qho ntaub uas hloov pauv tau
