Txheej txheem cej luam
Qhov kev ruaj ntseg thaiv kev sib cais nrog kev tiv thaiv kev tiv thaiv kev ua haujlwm ntawm kev hloov pauv input transistor tso zis, uas cais tawm thiab xa cov tswv yim tawm tswv yim los ntawm kev hloov kev sib cuag lossis cov kev sib txuas sib txuas hauv cov chaw muaj kev puas tsuaj mus rau thaj chaw nyab xeeb nrog cov zis transistor los ntawm kev tiv thaiv kev nyab xeeb. Kev kuaj xyuas kab yog ua tiav los ntawm LED nyob rau sab saum toj ntawm lub module. Lub dial hloov ntawm lub module yog siv los teem lub tswv yim thiab tso zis nyob rau hauv-theem los yog thim rov qab tswj, raws li zoo raws li pab kom los yog lov tes taw cov kab txhaum lub tswb ceeb toom muaj nuj nqi.
Cov khoom no yuav tsum muaj kev ywj pheej fais fab, nrog cov khoom siv hluav taws xob sib cais, cov tswv yim, thiab cov khoom siv tawm.
