Qhov Taw Qhia Qib Suab yog lub cuab yeej uas qhia qib suab los ntawm qhov ci ci ntawm lub teeb ci nrog kev hwm lub suab nrov.
Hauv Cov Lus Qhia no, Kuv yuav Qhia ua koj tus kheej lub suab ntsuas ntsuas nrog LM3915 IC thiab qee qhov LEDs. Peb tuaj yeem siv cov xim LEDs los qhia qhov sib zog.
LM3915 cov ntaub ntawv qhia meej tias IC yog ib qho kev sib txuas ua ke uas nkag siab txog qib sib piv thiab tsav kaum LEDs, LCDs lossis lub tshuab nqus tsev nqus cov lus qhia, muab logarithmic 3 dB/kauj ruam analog qhia. Ib tus pin hloov cov zaub los ntawm kab duab kab mus rau qhov pom teev txav. LED tsav tam sim no tau tswj hwm thiab ua haujlwm tau zoo, tshem tawm qhov xav tau rau kev txwv tam sim no. Tag nrho cov kab ke tso tawm tuaj yeem ua haujlwm los ntawm cov khoom siv qis li 3V lossis siab txog 25V.

Kauj Ruam 3: Kev sib hloov
Ntawm no koj tuaj yeem pom qhov Circuit Court ntawm daim ntawv qhia zaub mov.
Koj tuaj yeem pom kuv cov ntawv me me thiab nws yooj yim to taub thaum ua.
Muab tag nrho cov khoom siv rau ntawm daim ntawv qhia zaub mov raws li schematic.
Circuit txuas nrog, koj tuaj yeem rub tawm.
Kauj ruam 4: Koj Ua Tau
Qhov ntawd yog txhua tus txiv neej koj tau ua nws.
Xav tias dawb los tawm tswv yim.
