Tsuas muaj ob tus tiv thaiv siv rau hauv Circuit no. Ib qho yog 100KΩ thiab lwm qhov yog 1MΩ. Duab 1 tab tom qhia 1M resistor tso rau hauv txoj haujlwm R1 thiab daim duab 2 tab tom qhia txog 100K resistor tso rau hauv txoj haujlwm R2. Peb yuav paub tus nqi ntawm txhua tus tiv thaiv li cas?

Muaj ob txoj hauv kev los txheeb xyuas nws. Ib qho yog siv lub ntsuas ntsuas ntsuas nws tawm thiab lwm qhov yog nyeem qhov tsis kam tiv thaiv los ntawm cov xim xim luam tawm ntawm nws lub cev. Piv txwv li, hauv daim duab 5, tus nqi tiv thaiv ntawm resistor A yog 1MΩ thaum tus tiv thaiv B yog 100kΩ. Rau tus tiv thaiv A, thawj xim band yog xim av uas sawv cev rau tus lej 1 thiab pawg xim thib ob thiab xim thib peb yog xim dub uas sawv cev rau tus lej 0; plaub xim xim sawv cev rau qhov sib ntxiv, nws yog xim daj, tus lej sib xws yog 10k. Qhov xim thib tsib sawv cev rau kev ua siab ntev thiab xim yog xim av, tus lej sib xws yog ± 1%. Cia peb muab lawv tso ua ke peb tau txais 100 x 10k = 100 x 10000k = 1MΩ, kev zam yog ± 1%. Ib yam nkaus, cov xim xim txij li thawj txog qib tsib ntawm tus tiv thaiv B yog xim av, dub, dub, txiv kab ntxwv thiab xim av, peb tuaj yeem tau txais nws qhov kev tiv thaiv los ntawm 100 x 1k = 100kΩ, thiab nws qhov ua siab ntev yog%1%. Yog xav paub ntau ntxiv txog kev nyeem tsis txaus tus nqi los ntawm cov xim band thov mus rau mondaykids.com los ntawm txoj nyem rau koj tus nas kom qhib lub tab tshiab ntawm koj tus browser.

Cov electrolytic capacitors muaj polarity, ceg ntev yog anode thaum lwm tus yog cathode. Ua raws daim duab 6 mus rau daim duab 10 txhawm rau muab lub tshuab electrolytic tso rau hauv PCB. Koj tuaj yeem nyeem lub peev xwm ntawm lub tshuab hluav taws xob hluav taws xob los ntawm nws lub cev thiab ntxig nws mus rau txoj haujlwm sib xws uas muaj tus nqi tib yam luam tawm ntawm PCB. Cov ceg ntev yuav tsum tau muab tso rau hauv lub qhov ze ntawm '+' cim.

Kauj Ruam 3: Siv lub NPN thiab PNP Transistors rau PCB

Thov nco ntsoov tias lub tiaj tiaj ntawm transistor yuav tsum yog nyob rau tib sab ib nrab ntawm ib nrab luam tawm ntawm PCB. Rau 9013 NPN transistor muaj tus lej qauv, S9013, muab txiav rau ntawm lub tiaj tiaj ntawm lub transistor, thiab 9012 PNP transistor ua zoo ib yam. 9013 NPN thiab 9012 PNP transistors yuav tsum tau muab tso rau hauv thaj chaw uas muaj 9013 thiab 9012 feem ntau luam tawm ntawm PCB.

Kauj Ruam 4: Muab cov LED tso rau PCB

Lub teeb LED muaj qhov sib txawv, cov ceg ntev yuav tsum tau muab tso rau hauv lub qhov nyob ze lub cim '+' ntawm PCB. Thov ua raws daim duab 14 mus rau duab 17 kom ua tiav cov kauj ruam no.

Kauj Ruam 5: Muab tus Pin Header rau PCB

Qhov tseeb qhov no yog qhov hloov pauv qis zaus uas qhov zaus yog kwv yees li 1Hz. Qhov ntawd txhais tau tias nws oscillates ib zaug ib pliag. Thaum nias lub khawm hloov, lub tshuab hluav taws xob hluav taws xob, C1 tau them, thiab V1 tau ua thiab tom qab ntawd V2 tau ua thiab tom qab ntawd V3 tau ua, thiab tom qab ntawd V4 tau ua thaum kawg. Txawm li cas los xij, kev ua tiav ntawm V4 yuav tsis kav ntev, qhov tseeb nws yog sai. Vim tias thaum V4 tau ua, qhov hluav taws xob ntawm sab anode ntawm C2 tau poob qis txog li 0V nrawm uas ua rau qhov hluav taws xob ntawm lwm sab ntawm C2 ntog mus txog 0V nrawm, NPN transistor, V3 raug txiav tawm. Tab sis nyob rau lub sijhawm no, sab C2 txuas nrog lub hauv paus ntawm V3 pib them thiab txog li 1 thib ob qhov hluav taws xob tau nce mus txog qhov tsis ncaj ncees ntawm qhov hloov pauv, V3 rov ua dua. Cov txheej txheem no rov ua dua thiab rov ua dua uas ua kom muaj 1Hz teeb liab los tsav tus hais lus los ua Ticking Clock Sound Effect Circuit.
