Txoj haujlwm no tawm tswv yim txog txoj hauv kev ruaj ntseg rau koj li khoom. Qhov txiaj ntsig kawg ntawm txoj haujlwm yog kev hloov pauv los ntawm SMS. Yog li koj tuaj yeem hloov qhov no rau koj qhov project. Qhov kev zov me nyuam suav nrog tus lej xov tooj tso cai thiab tus neeg siv yuav tsum nkag mus rau qhov zoo "tus password" qhib qee yam.
Kuv yog tub ntxhais kawm Fabkis, yog li kuv sim ua qhov zoo tshaj plaws kom ua txhua yam "Lus Askiv"
Kauj Ruam 1: Cov Npe Khoom
Koj yuav xav tau:
- SIM 800L module
- SIM daim npav micro
- Ib Arduino Uno
- Hlau
- 110 KOhm resistor
- 120KOhm resistor
- A 2N2222 transistor
- A 1S lithium roj teeb
Kauj Ruam 2: Npaj SIM800L Module
Cov qauv no txias vim nws pheej yig tab sis nws ua haujlwm ntawm 3.3V cov laj thawj. Tsis tas li, thaum ua qee qhov xwm txheej tshwj xeeb, kuv siv roj teeb ntau (ntau dua 1A). Yog li COMPUTER TSIS MUAJ FEED NO MODULE. Siv lub roj teeb thiab xaim tus qauv raws li daim duab (Kuv siv lub teeb tsa ntawm lub vev xaib no; nws nthuav qhia tseem yuav ua li cas thiaj hu lossis tau txais kev hu nrog tib lub qauv no).
Kuv hais tab sis yog tias koj tsis hwm txoj hlua no, nws yuav tsis ua haujlwm.
Lawv, koj tuaj yeem ntxig Micro-SIM zoo li daim duab. Tab sis ua ntej, rho tawm peb tus lej PIN vim tias tus lej PIN thiab kuv qhov program tsis ua haujlwm ua ke. Koj yuav tau ntxiv kab rau txoj cai.
Txhawm rau paub yog tias sim800L ua haujlwm, txheeb xyuas cov xim daj. Yog tias nws ntsais muag txhua txhua 2/3s. Nws zoo, koj SIM tau sau npe hauv lub network. Yog tias koj tau txais, peb tuaj yeem mus rau theem tom ntej. yog tias tsis sim tawm sab nraud lossis tshawb xyuas lub roj teeb thiab cov xov hlau.
Kauj Ruam 3: Txoj Cai Tseem Ceeb
Cov cai tau nthuav tawm zoo li no
- Thawj qhov teeb tsa ib feem uas SIM800L tau muab tso rau hauv hom tau txais SMS
-
Lub voj uas txheeb xyuas yog tias lawv yog cov lus tshiab
- peb saib yog tus xov tooj paub
-
peb saib yog tias cov lus muaj tus password
- yog tias muaj, peb qhib
- yog tsis yog, sim dua
Nyob rau sab saum toj ntawm txoj haujlwm, koj tuaj yeem hloov kho tus lej tso cai thiab koj xav tau pes tsawg. Koj kuj tuaj yeem hloov tus password.
Kauj Ruam 4: Muaj Kev Lom Zem
Txoj cai yuav qhib lub transistor ob peb zaug. Qhov no tuaj yeem hloov lub laub khawm hauv cov chaw taws teeb. Ua li no, koj tuaj yeem tso lub transistor no rau hauv lub portal tej thaj chaw deb thiab yooj yim xa sms rau koj lub portal. Txog kuv qhov xwm txheej, kuv xub teeb tsa LED kom pom tias txhua yam ua haujlwm, tom qab ntawd kuv yuav qhib kuv lub nkas -las nrog qhov no.
Kuv vam tias txhua yam ua haujlwm. Yog tias tsis tiv tauj kuv ntawm [email protected]

Tus pej thuam tshiab tsis txhawb 2G cov cuab yeej ntxiv lawm. Yog li, kuv tsis tuaj yeem muab kev txhawb nqa rau txoj haujlwm no ntxiv lawm
