Nyob zoo phooj ywg, Hnub no kuv tab tom yuav ua LED Chaser Circuit siv NE555 IC thiab BC547 Transistor. Qhov LED Chaser no txawv ntawm lwm qhov LED Chasers Circuit.

Cia peb pib,

Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau -

(1.) LED - 3V x5 {Txhua xim}

(2.) Diode - 1N4007 x1

(3.) Transistor - BC547 x5

(4.) IC - NE555 x1

(5.) Capacitor - 25V 100uf x1

(6.) Capacitor - 25V 470uf x1

(7.) Resistor - 330 Ohm x5

(8.) Resistor - 1K x1

(9.) Resistor - 2.2K x1

(10.) Resistor - 10K x6

(11.) Lub hwj chim tawm tswv yim - 12V DC

Kauj Ruam 2: Transistor - BC547

Nov yog Pinout ntawm BC547 Transistor.

C - Tus neeg sau khoom, B - Base thiab

E - Emmiter

Kauj Ruam 3: Txuas Txhua Transistors

Txuas tus pin emmiter ntawm ib tus transistor rau tus pin tus pin ntawm lwm lub transistor thiab zoo li qhov no peb yuav tsum txuas txhua lub transistors raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 4: Txuas 10K Resistors

Solder 10K resistor rau tus pin tus pin ntawm txhua tus transistors thiab lwm sab ntawm 10K Resistor txuas ib leeg raws li txuas hauv daim duab.

Kauj Ruam 5: Txuas 330 Ohm Resistor

Tom ntej solder 330 ohm resistors rau +ve Ob txhais ceg ntawm txhua LEDs raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Txuas LEDs rau Transistors

Cov laug txuas tom ntej -ve ob txhais ceg ntawm txhua lub LEDs rau Cov pins ntawm txhua tus transistors li cov laug hauv daim duab.

Kauj Ruam 7: Txuas Diode thiab +ob txhais ceg ntawm Txhua LED

Tom ntej txuas +ve Ob txhais ceg ntawm txhua lub LEDs rau ib leeg raws li cov kab laug sab hauv daim duab.

Txuas Anode ntawm 1N4007 Diode rau 10K Resistors thiab Cathode rau +ve ob txhais ceg ntawm txhua LEDs raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 8: Txuas 2.2K Resistor

Solder 2.2K Resistor ntawm Anode thiab Cathode ntawm 1N4007 Diode raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 9: Txuas 470uf Capacitor

Tom ntej Solder +ve pin ntawm 25V 470uf capacitor rau 10K Resistor/Anode ntawm Diode thiab -ve tus pin rau Emmiter tus pin ntawm 5th transistor raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 10: Txuas Pin-2 thiab Pin-6 ntawm NE555 Ic

Solder tus pin-2 thiab tus pin-6 ntawm NE555 ic.

Kauj Ruam 11: Txuas Pin-4 thiab Pin-8

Next Solder tus pin-4 thiab tus pin-8 ntawm NE555 ic.

Kauj Ruam 12: Txuas 1K Resistor

Solder 1K Resistor ntawm Pin-7 thiab Pin-8 ntawm 555 IC.

Kauj Ruam 13: Txuas 10K Resistor

Solder 10K Resistor ntawm Pin-6 thiab Pin-7 ntawm 555 IC.

Kauj Ruam 14: Txuas 25V 100uf Capacitor

Tom ntej solder 100uf capacitor rau IC.

Solder +ve tus pin ntawm tus capacitor rau tus pin-2 thiab -ve tus pin rau tus pin-1 ntawm IC li cov laug hauv daim duab.

Kauj Ruam 15: Txuas Tus Hlau

Siv cov xaim xaim los ntawm +cov ceg ntawm txhua lub LEDs rau Pin-4 ntawm IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 16: Txuas Ob Tus Hlau

Cov kab txuas tom ntej los ntawm -ve tus pin ntawm 470uf capacitor rau tus pin -3 ntawm 555 IC raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 17: Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no txuas cov khoom siv hluav taws xob rau hauv Circuit Court.

Txuas +ve input fais fab mov rau Pin-8 thiab -ve input fais fab mov rau tus pin-1 ntawm 555 IC raws li koj tuaj yeem pom hauv daim duab.
