Yuav Ua Li Cas Tsis Siv Neeg Txoj Kev Teeb: 7 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Nyob zoo phooj ywg, Hnub no kuv yuav ua ib qho kev siv hluav taws xob ntawm txoj kev teeb pom kev tsis zoo. Qhov Circuit no yuav ua haujlwm tau zoo. Thaum sawv ntxov lub teeb yuav raug kaw.

Cia peb pib,

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

Cheebtsam yuav tsum tau -

(1.) LED - 3V x1

(2.) Roj teeb clipper x1

(3.) Roj teeb - 9V x1

(4.) LDR sensor x1

(5.) Transistor - BC547 x1

(6.) Resistor - 20K/33K ohm x1 {Hauv daim duab ob 10K resistors tau txuas nrog ua ke kom ua 20K resistor}

Kauj Ruam 2: Pins ntawm BC547 Transistor

Daim duab no qhia txog pinouts ntawm BC547 Transistor.

Raws li tus pin-1 yog Tus Sau ntawm cov transistor no, Pin-2 yog Base thiab Pin-3 yog Emmiter ntawm tus transistor no.

Kauj Ruam 3: Txuas LED

Txuas LED mus rau transistor.

Txuas -ve tus pin ntawm LED mus rau tus lej pin ntawm transistor raws li qhia hauv daim duab.

Kauj Ruam 4: Solder LDR

Tom ntej no peb yuav tsum tau muab LDR tso pov tseg.

Solder LDR rau Pin tus pin thiab tus pin emmiter ntawm transistor raws li qhia hauv daim duab.

Kauj Ruam 5: Txuas 20K Resistor

Tom ntej solder 20K resistor rau lub hauv paus pin ntawm transistor thiab hauv +ve pin ntawm LED raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Solder Battery Clipper Wire

Tam sim no peb yuav tsum tau txuas lub roj teeb clipper hlau rau hauv Circuit Court.

Solder +ve hlau ntawm roj teeb clipper rau +ve pin ntawm LED thiab

-ve xaim ntawm lub roj teeb clipper rau emmiter pin tus transistor raws li qhia hauv daim duab.

Kauj Ruam 7: Yuav Siv Li Cas Lub Teeb Tsis Siv Neeg Li Cas

Txuas lub roj teeb rau lub roj teeb clipper thiab soj ntsuam tias thaum lub teeb nyob ntawm LDR sensor ces LED tsis ci thiab thaum lub teeb tsis nyob ntawm LDR ces LED ci.

Kev Siv: Peb tuaj yeem siv qhov hluav taws xob no ua lub teeb pom kev vim tias nws yuav qhib thiab kaw thaum sawv ntxov thaum lub teeb yuav los ntawm LDR ces LED yuav tsis ci thiab thaum tsaus ntuj lub teeb yuav tsis poob ntawm LDR ces LED yuav ci hauv hmo ntuj thiab vice versa.
