(5.) Resistor - 1K x1

(6) Preset - 10K x1

(7.) LED - 3V x10 {Txhua xim}

(8.) Zero PCB

Kauj Ruam 2: Daim duab Circuit Court

Daim duab Circuit Court
Daim duab Circuit Court

Nov yog daim duab qhia chaw ntawm VU Meter.

Txuas tag nrho cov khoom siv raws li daim duab qhia chaw no.

Kauj Ruam 3: Txuas LEDs

Txuas LEDs
Txuas LEDs

Ua ntej tshaj plaws peb yuav tsum tso tag nrho LEDs rau PCB raws li koj xav tau xim ntawm LEDs.

+cov ceg ntawm LEDs yuav tsum yog sab saud thiab -ve ob txhais ceg yuav tsum nyob rau sab qis.

Kauj Ruam 4: Muab IC Base

Muab IC Base
Muab IC Base

Tom ntej no peb yuav tsum tso IC Base rau PCB raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 5: Cov Kav Cuam Pins ntawm IC Base thiab LEDs

Solder Pins ntawm IC Base thiab LEDs
Solder Pins ntawm IC Base thiab LEDs

Cov laug tom ntej +cov ceg ntawm txhua lub LEDs rau ib leeg thiab

Solder Txhua Tus Pins ntawm IC Base thiab -ve ob txhais ceg zoo li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Txuas -ve Ob txhais ceg ntawm LEDs

Txuas -ve Legs ntawm LEDs
Txuas -ve Legs ntawm LEDs

Tom ntej Txuas -ve Ob txhais ceg ntawm LEDs rau IC puag raws li tau hais hauv daim duab qhia chaw.

Solder -ve ceg ntawm LED-1 rau Pin-1 ntawm IC, Solder -ve ceg ntawm LED-2 rau Pin-18 ntawm IC, Solder -ve ceg ntawm LED-3 rau Pin-17 ntawm IC, Solder -ve ceg ntawm LED-4 rau Pin-16 ntawm IC, Solder -ve ceg ntawm LED-5 rau Pin-15 ntawm IC, Solder -ve ceg ntawm LED-6 rau Pin-14 ntawm IC, Cov laug -vaj ceg ntawm LED-7 mus rau Pin-13 ntawm IC, Solder -ve ceg ntawm LED-8 rau Pin-12 ntawm IC, Solder -ve ceg ntawm LED-9 rau Pin-11 ntawm IC thiab

Solder -ve ceg ntawm LED-10 rau Pin-10 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 7: Luv Pin-6 thiab Pin-7 ntawm IC

Luv Pin-6 thiab Pin-7 ntawm IC
Luv Pin-6 thiab Pin-7 ntawm IC

Kauj Ruam 8: Txuas 1K Resistor

Txuas 1K Resistor
Txuas 1K Resistor

Tom ntej txuas 1K Resistor rau hauv Circuit Court.

Solder 1K Resistor Ntawm Tus Pin-7 rau Pin-8 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 9: Muab Preset rau PCB

Muab Preset rau PCB
Muab Preset rau PCB

Kauj ruam 10: Txheeb Pin-2 thiab Pin4

Sort Pin-2 thiab Pin4
Sort Pin-2 thiab Pin4

Solder Pin-2 rau Pin-4 thiab nrog 10K Preset raws li muab rau hauv daim duab qhia chaw.

Kauj Ruam 11: Luv Pin-3 thiab Pin-9

Luv Pin-3 thiab Pin-9
Luv Pin-3 thiab Pin-9

Tom ntej luv luv tus pin-3 thiab Pin-9 thiab txuas lub xaim los ntawm Pin-9 rau +ve ntawm LEDs li cov laug hauv daim duab.

Kauj Ruam 12: Txuas Roj Teeb Clipper Hlau

Txuas Roj Teeb Clipper Hlau
Txuas Roj Teeb Clipper Hlau

Tom ntej solder roj teeb clipper hlau rau PCB.

Solder +ve hlau ntawm lub roj teeb clipper rau +ve Pin ntawm LEDs/Pin-3, 9 ntawm IC thiab -ve xaim rau Pin-2 ntawm IC raws li tau hais hauv daim duab qhia chaw.

Kauj Ruam 13: Txuas Aux Cable Hluav Taws Xob

Txuas Aux Cable Hlau
Txuas Aux Cable Hlau

Tam sim no peb tuaj yeem muab lub suab tawm tswv yim siv lub tshuab ua suab nrov/aux cable … rau hauv Circuit no.

{Ntawm no kuv muab nrog lub xov tooj cua pabcuam}

Solder +ve hlau ntawm aux cable rau Pin-5 ntawm IC thiab -v xaim mus rau Pin-2, 4 ntawm IC raws li koj tuaj yeem pom hauv daim duab kos.

Kauj Ruam 14: Yuav Siv Li Cas VU Meter

Yuav Siv Li Cas VU Meter
Yuav Siv Li Cas VU Meter
Yuav Siv Li Cas VU Meter
Yuav Siv Li Cas VU Meter

Txuas Cov Roj Teeb rau hauv Circuit Court thiab Plug-in aux cable rau Xov tooj Txawb thiab ua nkauj.

Raws li lub suab yuav yog zaj nkauj zoo li LEDs yuav ci.
