Kauj Ruam 1: Muab cov tshuaj tiv thaiv tso rau hauv PCB

Resistors tsis muaj polarity, tsuas yog ua raws daim duab 1 txog 3 txhawm rau txhawm rau ua rau cov Resistors rau hauv PCB. Txoj haujlwm sib xws ntawm txhua tus tiv thaiv ntawm PCB muaj tus nqi tiv thaiv luam tawm hauv cheeb tsam cov duab plaub dawb. Ua ntej tso cov resistors rau hauv PCB koj yuav tsum ua kom ntseeg tau tias txhua tus tiv thaiv nyob hauv qhov chaw raug lossis lub Circuit Court yuav tsis ua haujlwm zoo. Yuav ua li cas txhawm rau txheeb xyuas tus nqi tiv thaiv ntawm tus tiv thaiv? Muaj ob txoj hauv kev los ua li ntawd, ib qho yog nyeem qhov muaj txiaj ntsig los ntawm cov xim xim luam tawm ntawm nws lub cev thiab lwm qhov yog siv lub ntsuas cua los ntsuas nws. Tab sis hauv txoj haujlwm no, kuv pom zoo kom koj siv lub multimeter los ntsuas nws uas tuaj yeem txuag koj ntau lub sijhawm. Yog tias koj xav paub yuav ua li cas nyeem tus nqi tiv thaiv los ntawm cov kab xim thov mus rau Yuav Ua Li Cas Nyeem Cov Xim Xim los ntawm Resistors.

Kauj Ruam 2: Muab cov Capacitors tso rau hauv PCB

Ua raws daim duab 4 txog 6 txhawm rau txhawm rau txhawm rau 104 Capacitors thiab Electrolytic Capacitors rau hauv PCB. Thov nco ntsoov tias cov khoom siv hluav taws xob muaj qhov sib txawv, cov ceg ntev yuav tsum tau muab tso rau hauv lub qhov ze ntawm '+' lub cim ntawm PCB thaum cov ceg luv nyob ze ntawm pab pawg dawb yuav tsum tau muab tso rau hauv lub qhov nyob hauv thaj chaw duab ntxoov ntxoo ntawm PCB. Lub 103 thiab 104 Capacitors tsis muaj qhov sib txawv uas tsis xav tau kev saib xyuas txog kev coj.

Kauj Ruam 3: Siv lub 9013 Transistors rau hauv PCB

Qhov tiaj tus ntawm 9013 NPN Transistors yuav tsum yog nyob rau tib sab ntawm txoj kab uas hla ntawm ib nrab ib ncig luam tawm ntawm PCB. Txhawm rau txheeb xyuas tus lej tus qauv ntawm tus transistor tsuas yog xav tau nyeem tus lej carved ntawm lub tiaj tiaj ntawm transistor, raws li qhia hauv duab 8.

Kauj Ruam 4: Muab cov diode tso rau hauv PCB

Diodes muaj polarity, qhov kawg dub cim nrog lub voj voog liab hauv daim duab 10 txuas nrog rau qhov tsis zoo kawg (Qhov Muaj Peev Xwm Tsawg).

Kauj Ruam 5: Muab lub taub hau taub hau thiab lub Microphone thiab LED rau hauv PCB

Muab qhov luv luv ntawm lub taub hau pins tso rau hauv PCB thiab tawm qhov kawg rau kev txuas sab nraud. Lub voj voos dawb ntawm PCB yuav tsum yuav luag tag nrho nrog lub microphone raws li qhia hauv duab 12. Lub teeb pom kev zoo LED tau hais tias cov ceg ntev yuav tsum tau muab tso rau hauv lub qhov ze ntawm '+' lub cim ntawm PCB. Raws li tam sim no txoj haujlwm tau ua tiav.

Kauj Ruam 6: Txheeb Xyuas

Lub voj voog no yog tsim los ntawm ob lub ntsiab lus tseem ceeb hauv qab, sab laug yog ob-theem ib txwm siv cov tshuab hluav taws xob ua hluav taws xob, sab xis yog bistable Circuit Court multivibrator. R1 thiab C1 los tsim RC network txhawm rau thaiv lub suab tsis nyob hauv thaj tsam li 1kHz. Thaum muaj lub teeb liab siv rau lub microphone, lub teeb liab tuaj yeem ua kom nrov nrov los ntawm Q1 thiab Q2, raws li peb paub, cov pa hluav taws xob tso tawm ntau zaus ua rau kwv yees li 180 ° theem hloov pauv rau lub teeb liab, yog li cov teeb liab tsis zoo yuav tsim tawm los ntawm tus neeg khaws khoom ntawm Q2 thiab xa mus rau C5 thiab C6 uas ua rau lub xeev rov qab rau ob qho tib si ntawm Q3 thiab Q4. Piv txwv li, yog tias Q3 Qhib thiab Q4 Tawm, thaum lub teeb liab tau muab xa mus rau C5 thiab C6, tom qab ntawd Q3 hloov mus rau hauv Lub Xeev, Q4 Hloov mus rau Hauv Lub Xeev, LED nyob. Thaum siv lub teeb liab rau lub microphone dua, Q3 yuav raug hloov mus rau Hauv Lub Xeev, Q4 yuav Yog Lub Xeev, LED Tawm. Yog tias tsis muaj lub teeb liab ntxiv rau lub microphone, Logic State ntawm bistable multivibrator Circuit yuav ib txwm khaws lub xeev tam sim no.
