2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Hauv cov lus qhia no peb yuav tshawb nrhiav yuav tsim cov ntawv qhia zaub mov li cas, nyeem qhov ntsuas kub los ntawm TC74A0 sensor thiab tso tawm "qhov tseem ceeb" (qhov no yog xov tooj ntawm tes) hauv qhov uas tsis muaj qhov kawg, tab sis txwv rau arduino's on board memory.

Peb yuav siv

-Array

-Liquid siv lead ua zaub

-Cov keyboard

Cov neeg siv phau ntawv qhia suav nrog hauv cov kauj ruam kawg.

Kauj Ruam 4: TUS NEEG UA HAUJ LWM

1. Thaum hloov pauv ntawm qhov haujlwm, qhov chaw thau khoom lossis tos txais yuav tshwm sim.

2. Lub vijtsam “Enter Password” yuav tshwm sim, lub vijtsam no tso cai rau koj nkag mus 4 tus cim, ntawv lossis lej, tus lej raug yog: 5466, qhov no yuav tso cai rau koj nkag mus rau cov ntawv qhia zaub mov tseem ceeb.

3. Thaum nkag mus rau tus lej nkag mus raug, cov ntawv qhia zaub mov tseem ceeb yuav tshwm sim nrog 4 txoj hauv kev xaiv mus rau qhov ua haujlwm sib txawv.

· A - Sau tus neeg siv tus lej xov tooj.

o Sau 10 tus lej txhawm rau txuag tus neeg siv rau hauv kab ke

o Tom qab 10 tus lej tau nkag mus nias " *" txhawm rau ntxiv cov neeg siv, lossis nias "#" kom rov qab mus rau lub tshuab raj tseem ceeb

· B - Zaub txuag cov neeg siv

o Cov neeg siv yuav hla dhau lub vijtsam, lawv tau tshwm rau 3 vib nas this txhua, sai li sai tau txhua tus neeg siv tau tso tawm nplooj ntawv yuav kaw thiab rov qab mus rau cov ntawv qhia zaub mov tseem ceeb.

o Yog tias tsis muaj cov neeg siv tau ntxiv rau hauv cov ntawv xaiv A, nws yuav tso tawm "TSIS SAVED USERS".

· C - Qhia qhov ntsuas kub nyob

o Nias " *" kom rov qab mus rau lub tshuab raj tseem ceeb

· D - Zaub cov ntawv luv

o Qhia tus tsim lub npe thiab cov ncauj lus nws tau suav ua ke nrog rau hnub tim.
