Nyob zoo phooj ywg, Hnub no kuv tab tom yuav ua ib lub Circuit Court ntawm super teebmeem teeb nrog LED Sawb thiab LED.

Cia peb pib,

Kauj Ruam 1: Nqa Txhua Cheeb Tsam Raws Li Qhia Hauv Qab

Cheebtsam yuav tsum tau -

(1.) IC - LM555 x1

(2.) LED Sawb

(3.) LED - 3V x1

(4.) Resistor - 330 ohm x1

(5.) Resistor - 220 ohm x1

(6.) Capacitor - 25V 220uf x1

(7.) Fais fab mov - 12V DC

(8.) Roj teeb - 9V x1

(9.) Clipper roj teeb

Kauj Ruam 2: Luv Pin-2 rau Pin-6

Firstly peb yuav tsum tau luv tus pin ntawm ic.

Txuas tus pin-2 mus rau tus pin-6 ntawm IC li cov laug hauv daim duab.

Kauj Ruam 3: Rov Ntxiv Pin-4 rau Pin-8

Tom ntej no peb yuav tsum tau txuas tus pin-4 rau tus pin-8 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 4: Txuas 330 Ohm Resistor

Tom ntej txuas 330 ohm resistor ntawm tus pin-7 rau tus pin-8 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 5: Txuas 220 Ohm Resistor

Solder 220 ohm resistor ntawm tus pin-6 rau tus pin-7 ntawm IC.

Kauj Ruam 6: Txuas Capacitor

Tom ntej no peb yuav tsum txuas 220uf electrolytic capacitor rau hauv Circuit Court.

> Solder +ve tus pin ntawm lub capacitor rau tus pin-2 ntawm IC thiab

solder -ve tus pin ntawm lub capacitor rau tus pin -1 ntawm ic raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 7: Txuas LED mus rau Circuit

Tom ntej solder +ve ceg ntawm LED rau tus pin-4 ntawm IC thiab

solder -ve ceg ntawm LED rau tus pin -3 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 8: Txuas Roj Teeb Clipper

Solder +ve hlau ntawm lub roj teeb clipper rau tus pin-8 ntawm IC thiab

Solder -ve xaim ntawm Roj teeb clipper rau tus pin -1 ntawm IC li cov laug hauv daim duab.

Kauj Ruam 9: Txuas Roj Teeb

Tam sim no txuas lub roj teeb rau lub roj teeb clipper thiab qhov tshwm sim yuav tshwm sim LED yog ntsais muag.

NCO TSEG: Peb tuaj yeem txuas LED Sawb hloov ntawm LED tab sis LED Sawb yuav tsum yog 4-5V ces LED Sawb yuav ci nrog cov teebmeem zoo.

Kauj Ruam 10: Txuas LED Sawb Hloov LED

Tom ntej Txuas LED Sawb rau lub Circuit Court tsis siv LED. (Polarity ntawm LED Sawb yuav zoo ib yam li LED)

Kauj Ruam 11: Txuas 12V DC Fais Fab Khoom

Yog tias LED Sawb tsis ci nrog 9V Roj teeb ces txuas 12V DC lub zog hluav taws xob rau hauv Circuit Court thiab tam sim no LED Sawb yuav muab cov txiaj ntsig zoo tshaj, Tab sis nrog 12V lub zog xa hluav taws xob qhov kev siv hluav taws xob no tsis tuaj yeem nkag mus tau ntev tom qab qee lub sijhawm IC yuav tuag. Yog li siv qhov Circuit no nrog 9V DC.
