Nyob zoo phooj ywg, Hnub no kuv yuav ua VU Meter Meter Circuit uas yuav qhia qib suab hauv LED Hauv qhov VU Meter no kuv yuav siv 10 LED.
Cia peb pib,
Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau
(1.) IC - 3915 x1
(2.) IC puag - 18 Pin x1
(3.) Roj teeb - 9V x1
(4.) Clipper roj teeb x1
(5.) Resistor - 1K x1
(6) Preset - 10K x1
(7.) LED - 3V x10 {Txhua xim}
(8.) Zero PCB
Kauj Ruam 2: 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
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
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
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
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
Kauj Ruam 8: 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
Kauj ruam 10: Txheeb 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
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
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
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
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.
