Video: Yuav Ua Li Cas Thiaj Li Ua Ob Qhov LED Blinker Circuit ntawm PCB: 11 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 qhov Project Circuit of Double LED Blinker. Qhov Circuit no yog ua los ntawm Timer IC 555.
Cia peb pib,
Kauj Ruam 1: Siv Tag Nrho Txhua Yam Raws Li Qhia hauv qab no
Cheebtsam yuav tsum tau -
(1.) IC - 555 x1
(2.) IC Base - 8 Pin x1
(3.) Capacitor - 16V 100uf x1
(4.) Resistor - 10K x1
(5.) Resistor - 1K x1
(6.) Resistor - 220 ohm x1
(7.) LED - 3V x4
(8.) PCB
(9.) Roj teeb - 9V x1
(10.) Roj teeb clipper x1
Kauj Ruam 2: Daim duab Circuit Court
Txuas tag nrho cov khoom siv raws li daim duab qhia chaw.
Kauj Ruam 3: Solder IC Base ntawm Pcb
Solder 8-Pin IC puag ntawm PCB pawg thawj coj saib.
Kauj Ruam 4: Txuas 1K Resistor
Luv tus pin-4 thiab tus pin-8 ntawm IC siv jumper hlau thiab
Tom ntej no peb yuav tsum txuas 1K tus tiv thaiv rau tus pin-7 rau tus pin-8 ntawm IC raws li cov kab laug sab hauv daim duab.
Kauj Ruam 5: Cov laug LEDs hauv Series
Txuas ob LEDs hauv kab thiab txuas +ve ntawm LED rau Pin-8 ntawm IC raws li tau hais hauv daim duab qhia chaw.
Kauj Ruam 6: Txuas 220 Ohm Resistor
Tom ntej solder 220 ohm Resistor ntawm tus pin -3 rau -ve ntawm LED raws li daim duab qhia chaw.
Kauj Ruam 7: Solder Capacitor thiab Tseem Muaj 2-LEDs
Tam sim no cov laug Ntau ntxiv ob lub LEDs ntawm pcb raws li muab hauv daim duab qhia chaw thiab
kuj txuas 16V 100uf capacitor.
~ Solder -ve tus pin ntawm lub capacitor rau tus pin-1 thiab +ve tus pin ntawm lub capacitor rau tus pin-2 ntawm IC raws li daim duab qhia chaw.
~ Tsis tas li luv tus pin-2 thiab tus pin-6.
Kauj Ruam 8: Solder 10K Resistor
Tom ntej no peb yuav tsum tau solder 10K resistor ntawm tus pin-6 rau tus pin-7.
Kauj Ruam 9: Txuas Cov Roj Teeb Clipper Hlau
Tam sim no txuas Cov roj teeb clipper hlau rau hauv Circuit Court.
Solder +ve hlau ntawm lub roj teeb clipper rau tus pin-8 ntawm IC thiab
solder -ve tus pin ntawm lub roj teeb clipper rau tus pin -1 ntawm 555 IC.
Kauj Ruam 10: Circuit Tiav
Tam sim no peb cov Circuit tau ua tiav yog li txuas lub roj teeb rau lub roj teeb clipper thiab tam sim no koj tuaj yeem pom cov LEDs ntsais muag.
Kauj ruam 11: Qhov tshwm sim
Cov txiaj ntsig - Raws li koj tuaj yeem pom hauv daim duab LEDs tau pib ntsais muag.
LEDs ntsais nrog 1/2 lub sijhawm thib ob rau ib leeg.
Yog tias koj xav ua ntau txoj haujlwm hluav taws xob ces ua raws utsource123 tam sim no.
