Kauj Ruam 28: Yuav Siv Nws Li Cas
Lub hom phiaj ntawm qhov kev tsim no yog ua kom teeb tsa thiab khiav lub sijhawm ua kom yooj yim li sai tau.
Lub sijhawm siv sijhawm muaj peb hom: hom kev pabcuam, hom sijhawm, thiab hom kev ncua. Hom yog txiav txim siab los ntawm kev taw qhia ntawm lub sijhawm: hom kev ua haujlwm thaum lub khawm kov lub ntsej muag nyob rau sab saum toj, hom timer thaum nws nyob hauv qab, thiab ncua sijhawm thaum lub sijhawm nyob ntawm nws sab.
QHOV KEV PAB
Thaum koj xub qhib nws koj yuav pom lub qhov muag daj "tus cursor" nyob hauv qab ntawm LED kab txaij. Kov lub khawm khawm kom ntxiv sijhawm hauv 15 vib nas this nce ntxiv. Txhua 15 vib nas this tau pom tias yog lub teeb liab. Thaum koj mus txog 60 vib nas this, cov xim liab tau hloov pauv los ntawm cov xim xiav, uas sawv cev rau ib feeb. Tuav lub pob kom ntxiv feeb ntxiv mus kom txog thaum lub pob raug tso tawm. Txhua feeb thib tsib teev yog xim dawb kom yooj yim pom tag nrho.
TIMING MODE
Tig lub timer dua pib suav rov qab. Txhua qhov ntawm qhov pib pib teeb, tsis hais txog lub sijhawm tag nrho - qhov no yog kev xaiv tsim ntawm kuv ib feem. Koj kuj tseem tuaj yeem ua haujlwm nws kom txhua qhov teev ib txwm txhais tau tias yog lub sijhawm zoo ib yam.
Dots poob ib ntawm ib qho kom txog thaum lub sijhawm dhau mus. Tom qab ntawd lub sijhawm teev qhia pom cov xim "qhov kawg" txog li 15 vib nas this. Txhawm rau rov qab mus rau hom program, tig lub timer rov qab. Tus cursor daj yuav qhia dua. Yog tias koj pib lub sijhawm ncua tam sim ntawd yam tsis muaj lub program nws, nws yuav siv sijhawm dhau los.
Qhov zoo ntxiv rau lub sijhawm no yuav yog tus hais lus me me los ua suab, tshwj xeeb yog lub tswb nrov thaum kawg.
PAUSE MODE
Thaum lub sijhawm ua haujlwm sijhawm koj tuaj yeem ncua lub sijhawm ntsuas los ntawm tig nws 90 degrees thiab so nws ntawm ib sab. Lub sijhawm teev teev khov nyob hauv qhov chaw, thiab mem tes maj mam qhia tias lub sijhawm tau tos kom rov pib dua. Tig nws rov qab los txuas ntxiv lub sijhawm, lossis lwm txoj hauv kev rov qab mus rau hom haujlwm.
