Nyob zoo tav su, cov saib thiab nyeem. Hnub no kuv yuav qhia koj txog LED ntsuas ntsuas lub ntsuas, ua los ntawm kev sib koom ua ke LM3915.

Kauj Ruam 1: Txuas rau Cov Xov Tooj Cua

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.

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

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.
