Nyob zoo phooj ywg, Hnub no kuv yuav ua Kov ON thiab OFF Circuit siv LM555 IC. Thaum peb yuav kov ntawm xov ntawm ib sab ces LED yuav ci thiab thaum peb yuav kov ntawm cov xov hlau ntawm lwm sab ces LED yuav tig OFF thiab rov ua dua.

Cia peb pib,

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

Cheebtsam yuav tsum tau -

(1.) LED - 3V x1

(2.) Resistor - 220 ohm

(3.) IC - LM555

(4.) Txuas xov hlau

(5.) Roj teeb - 6V

Kauj Ruam 2: Txuas Pins ntawm IC

Solder Pin-4 thiab Pin-8 ntawm IC no.

Kauj Ruam 3: Txuas LED

Tom ntej no peb yuav tsum tau sib dhos +tus pin ntawm LED mus rau Pin-3 ntawm IC.

Kauj Ruam 4: Solder 220 Ohm Resistor

Solder 220 ohm resistor ntawm -ve tus pin ntawm LED rau Pin -1 ntawm IC.

Kauj Ruam 5: Solder Ob Lub Xov Tooj rau ON

Cov xov hlau txuas tom ntej hauv Pin-1 thiab Pin-2 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Solder Ob Qhov Txuas Ntxiv rau OFF

Tom ntej no peb yuav tsum txuas ob lub xov hlau txuas ntxiv hauv tus pin-6 thiab Pin-8 ntawm IC li cov laug hauv daim duab.

Kauj Ruam 7: Txuas 6V Cov Khoom Siv Hluav Taws Xob

Solder +ve hlau ntawm Lub Hwj Chim muab rau Pin-8 thiab

-ve xaim roj teeb rau Pin-1 ntawm IC raws li qhia hauv daim duab.

NCO TSEG: Muab 6V Cov Khoom Siv Hluav Taws Xob.

Kauj Ruam 8: Tiav Circuit Tiav

Tam sim no peb Circuit tau ua tiav.

Yuav ua li cas Circuit Court ua haujlwm -

Thaum peb yuav kov xov tooj ntawm Pin-1 thiab tus pin-2 ces LED ci ntsa iab thiab Rau Tua Tawm ntawm LED peb yuav tsum kov xov tooj ntawm Pin-8 thiab Pin-6 ntawm IC. As koj tuaj yeem pom hauv daim duab.

Yog tias koj xav ua ntau txoj haujlwm hluav taws xob ces ua raws utsource123 tam sim no.
