Kauj Ruam 2: LM3915 Thaiv Daim Duab
Daim duab LM3915 thaiv muaj kaum tus neeg sib piv, ntawm qhov rov qab tawm tswv yim uas siv lub teeb liab nkag los ntawm qhov tsis ua haujlwm tsis zoo, thiab cov tswv yim ncaj qha txuas nrog rau cov kais ntawm qhov hluav taws xob tiv thaiv qhov sib faib.
Cov txiaj ntsig ntawm cov sib piv yog dab dej tam sim no cov tshuab hluav taws xob, uas tso cai rau koj txuas LEDs yam tsis siv kev txwv kev tiv thaiv. Qhov taw qhia tuaj yeem ua tau los ntawm ib qho LED (hom hom), lossis los ntawm kab ntawm cov luminous LEDs, qhov siab uas yog sib piv rau qib ntawm cov teeb liab nkag (hom kab).
Kauj Ruam 3: Microphone Amplifier Circuit
Lub teeb liab tawm tswv yim yuav los ntawm lub tshuab tso suab microphone, sib sau ua suab nrov ua haujlwm qis NE5532, ntawm cov tswv yim ntawm LM3915 microcircuit nti.
Lub Circuit Court muaj ob theem nrog kev tswj tau nce. Qhov nce ntawm thawj theem yog kho tsis tu ncua los ntawm lub zog ntsuas hauv thaj tsam ntawm 1… 10 zaug. Qhov nce ntawm theem ob tuaj yeem hloov pauv hauv cov kauj ruam uas siv lub jumper. Yog tias cov jumper ua tsis tau luv ua ke, qhov nce yuav yog qhov loj tshaj, uas tau txiav txim siab los ntawm qhov sib piv ntawm R8 thiab R5 resistors. Thaum lub jumper txuas nrog R6 lossis R7 ua ke nrog R8, qhov nce yuav tsawg dua.
Kauj Ruam 4: Tsim Circuit Court thiab PCB Layout
Ntawm EasyEDA lub vev xaib, ib qho kev sib txuas tau tsim los ntawm ob daim duab qhia chaw thiab hloov pauv mus rau hauv ob-sided luam tawm Circuit Board.
Daim duab hluav taws xob sib cais thiab lub rooj tsav xwm luam tawm tau tsim rau LEDs.
Muaj ob lub LEDs txuas nrog hauv kab ntawm txhua qib qhia.
Kauj ruam 5: 3D Visualization
Hauv KOMPAS 3D Kuv tau tsim tus qauv nyob rau hauv daim ntawv ntawm tus pej thuam ntawm qhov sib npaug sib npaug. Kuv yuav siv 5 hli tuab cov iav organic ua cov duab plaub los txhim kho lub teeb tawg ntawm LED ntsuas.
Kauj Ruam 6: Txhim Kho Cov Xov Tooj Cua ntawm Cov Tswj PCB
Cia peb npaj mus rau teeb tsa cov khoom siv xov tooj cua ntawm lub rooj tsav xwm tswj hwm.
Kauj Ruam 7: Kev teeb tsa LEDs ntawm PCB
Tom ntej no, peb mus rau qhov teeb tsa ntawm lub rooj tsav xwm luam tawm thiab LED tawm.
Kauj Ruam 8: Txuas Cov Tswj Circuit Board thiab LED Circuit Board
Nrog kev pab cuam txuas, txuas lub rooj tsav xwm tswj hwm thiab lub rooj tsav xwm LED ua ke.
Kev sib txuas ntawm cov pob qij txha tau ua tiav ob qho tib si sab nraud thiab sab hauv.
Kauj Ruam 9: Sib dhos ntawm Ntauwd Los Ntawm Cov Duab Duab
Tom ntej no, peb npaj mus rau lub rooj sib txoos ntawm tus pej thuam los ntawm cov duab plaub thiab cov iav pob tshab organic.
Rau kev teeb tsa thiab ntxiv qhov nruj ntawm cov duab plaub ntawm lub pej thuam kuv yuav siv ob lub m4 studs.
Cov yas yas ntawm qhov siab 5 hli tau teeb tsa rau qhov nrug nruab nrab ntawm cov ntu.
Kauj Ruam 10: Sib Sau Ua Ke
Kauj Ruam 11: Xaus Kev Qhia
Ua tsaug rau txhua tus saib cov vis dis aus thiab nyeem kab lus. Tsis txhob hnov qab nyiam nws thiab sau npe mus rau "Hobby Home Electronics" channel. Qhia rau phooj ywg. Ntxiv mus yuav muaj cov kab lus thiab cov vis dis aus txaus nyiam dua.

Yooj Yim 20 LED Vu Meter Siv LM3915: Lub tswv yim los ua VU meter tau nyob ntawm kuv cov npe teev npe ntev. Thiab thaum kawg kuv tuaj yeem ua tam sim no.VU lub ntsuas cua yog lub ntsuas hluav taws xob rau qhov ntsuas ntawm lub teeb liab lub zog. VU meter Circuit feem ntau yog siv rau lub tshuab hluav taws xob

Tsis Muaj Tus Menyuam Tam Sim No, Tus Cwj Pwm Coj Tus Cwj Pwm Cuam Tshuam Tus Menyuam Mus Pee Nyob Hauv Koj Lub Tsev: Kuv tau ntxhov siab los ntawm kuv tus miv tias nws nyiam ua pee ntawm kuv lub txaj, Kuv tshuaj xyuas txhua yam nws xav tau thiab kuv kuj coj nws mus rau tus kws kho tsiaj. Tom qab kuv daws txhua yam kuv tuaj yeem xav thiab mloog tus kws kho mob cov lus, Kuv paub tias nws tsuas muaj qee tus cwj pwm tsis zoo. Yog li ntawd
