Lub Teeb Pom Kev Zoo Ob Chav LED Blinker: 13 Cov Kauj Ruam

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

Nyob zoo phooj ywg, Hnub no kuv tab tom yuav ua ib qho Circuit of Light Sensitive Double LED Blinker. Nws txhais tau hais tias LEDs yuav ntsais muag hloov thaum tsis muaj lub teeb yuav poob ntawm LDR thiab LEDs yuav ci tas li thaum lub teeb yuav nyob ntawm LDR.

Cia peb pib,

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

Cheebtsam yuav tsum tau -

(1.) Transistor - BC547 x2

(2.) LDR x2

(3.) LED - 3V x2 {Txhua xim}

(4.) Capacitor - 16V 220uf x2

(5.) Resistor - 220 ohm x1

(6.) Txuas xov hlau.

(7.) Roj teeb - 9V

(8.) Clipper roj teeb

Kauj Ruam 2: Transistor - BC547

Pin-1 ntawm tus transistor no yog tus sau, Pin-2 yog Base thiab

Pin-3 yog Emmiter ntawm tus transistor no.

Kauj Ruam 3: Txuas LED mus rau Transistor

Solder -ve ceg ntawm LED rau Collector tus pin ntawm transistor.

Kauj Ruam 4: Txuas LDR rau Base ntawm Transistor

Tom ntej solder ib ceg ntawm LDR rau Base tus pin ntawm Transistor li cov laug hauv daim duab.

Kauj ruam 5: Txuas +ve Leg ntawm LED

Txuas Txuas Ntxiv +txuas ntawm LED mus rau sab ceg ntawm LDR raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Ua Zoo Li No Ntawm Lwm Tus Transistor

Tom ntej no peb yuav tsum txuas ib qho ntxiv LED thiab LDR mus rau lwm qhov transistor ntxiv raws li qhia hauv daim duab.

Kauj Ruam 7: Txuas Emmiter Pins ntawm Ob Lub Transistors

Tom ntej solder emmiter pins ntawm ob lub transistors li solder hauv daim duab.

Kauj Ruam 8: Txuas Capacitor

Solder +ve pin ntawm Electrolytic capacitor rau Collector pin ntawm 2nd transistor thiab

Solder -ve tus pin ntawm lub capacitor rau tus lej pin ntawm 1st transistor raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 9: Txuas Ntxiv 220uf Capacitor

Solder +ve tus pin ntawm tus capacitor no rau Collector tus pin ntawm 1st transistor thiab

-ve tus pin ntawm lub capacitor rau Base tus pin ntawm 2nd transistor li solder hauv daim duab.

Kauj ruam 10: Txuas +ve Leg ntawm Ob LEDs

Kauj Ruam 11: Txuas 220 Ohm Resistor

Solder 220 ohm resistor to +ve leg of LED as solder in the picture.

Kauj Ruam 12: Txuas Roj Teeb Clipper Hlau

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

Solder +ve hlau ntawm lub roj teeb clipper rau 220 ohm resistor thiab

-ve xaim rau emmiter tus pin ntawm transistors zoo li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 13: Txuas Roj Teeb

Tam sim no txuas lub roj teeb rau lub roj teeb clipper thiab saib qhov ntawd -

1] Thaum lub teeb yuav nyob ntawm LDR ces ob qho tib si LEDs yuav ntsais ntsais li koj pom hauv daim duab-1 thiab daim duab-2.

2.] Thaum lub teeb yuav tsis nyob ntawm LDR ces LEDs yuav txuas sib txuas raws li koj pom hauv daim duab-3 thiab daim duab-4.
