Kuv tau yaum kom ntxiv qee qhov bling rau Christmas Ornament. Yog li qhov yooj yim tshaj plaws hauv Circuit los ua qhov no yuav yog siv cov multivibrator (Flip Flip) Circuit. Tab sis tom qab ravaging los ntawm kuv cov npe ntawm cov khoom kuv tsis tuaj yeem nrhiav ib qho tsim nyog transistors thiab capacitor. Kuv paub tias kuv tuaj yeem xaj qhov no yooj yim tab sis nws yuav siv sijhawm, thiab kuv muaj lub siab xav tsim lub Circuit tam sim no. Yog li kuv siv NE555 lub sijhawm ntsuas hluav taws xob hloov pauv.

Kauj Ruam 1: Tsim Hnub So Kho Kom Zoo Nkauj

Tsim Cov Nyiaj So Hnub So raws li cov lus qhia qhia. Kuv siv BW cov lus qhia thiab cia kuv Tus Tub thiab Tus Ntxhais muaj kev lom zem rau xim nws. Tsis txhob txhuam nws kom txog thaum ua tiav, thaum koj mus txog qib 6, muab cov hlua dai rau saum. Tom qab ntawd koj tuaj yeem lo rau nruab nrab ib feem rau hauv qab, tab sis tsis txhob lo rau sab saum toj, zoo li peb yuav tso peb lub teeb ntsais ntsais.

Kauj Ruam 2: Astable Multivibrator Circuit

Thawj daim duab yog Astable Multivibrator Circuit siv NE555 timer Circuit. Yog tias koj tsis txaus siab rau cov txheej txheem txuj ci koj tuaj yeem hla cov kauj ruam no. Lub NE555 lub sijhawm tau muaj ntau yam kev siv, ib qho ntawm lawv yog cov khoom siv sib kis tau zoo. Raws li lub npe hais qhia, nws tau tig lub teeb rau thiab tawm. Qhov no ua tiav los ntawm kev them tus nqi hluav taws xob los ntawm lub ntsuas thiab tus lej pib. Thaum lub capacitor puv, nws yuav tso tawm los ntawm tus pin 7 (Tshem tawm) ntawm 470k ohm resistor uas tom qab ntawd txuas los ntawm cov zis thiab yog li teeb pom kev zoo rau LED, peb siv 1K ohm resistor txwv qhov tam sim no uas dhau los ntawm LED. Thaum tso tawm, lub capacitor yuav pib them dua, tag nrho lub voj voog rov ua nws tus kheej.

Peb yuav tsum txuas tus pin rov pib dua rau Vcc, yog li peb txuas qhov no ua ke nrog tus pin 8.

Kuv tsis muaj NE555, tab sis kuv muaj NE556, uas suav nrog ob NE555 hauv ib pob. Yog li daim duab thib ob yog qhov kuv siv rau kuv qhov Circuit. Kuv kuj tsis tuaj yeem nrhiav 1 micro farad capacitor yog li kuv hloov qhov no nrog 2 x 100nF capacitor ua ke yog li kev sib xyaw ua ke yog 200nF uas yog 1/5 ntawm 1micro Farad. Qhov no ua rau LED ntsais sai dua, vim nws yuav tsub nqi thiab tso tawm sai dua.

Kauj Ruam 3: Txuas Lub Circuit Court

Kuv siv txoj hauv kev qhwv cov xov hlau los txuas rau hauv Circuit Court. Ua ntej kuv txuas 1K rau tus pin 1 thiab tus pin 14. Tom qab ntawd kuv txuas 180K ohm resistor ntawm tus pin 1 thiab tus pin 2, raws li qhia hauv daim duab thib ob. Tus pin txuas 2 (Threshold) nrog tus pin 6 (Trigger) raws li qhia hauv daim duab thib peb.

Kauj Ruam 4: Foob Siv Shrink Wrap

Tom qab ntawd kuv kaw tus pin 1 nrog qhwv qhwv kom tiv thaiv nws los ntawm kev sib tw luv. Qhov no tau pom hauv thawj daim duab.

Daim duab thib ob tau qhia kuv qhov kev npaj los txuas 2 x 100nF capacitor ua ke, tom qab ntawd daim duab thib peb qhia txog kev txuas ntawm lub capacitors rau tus pin 2 (Threshold) thiab tus pin 7 (GND) qhia hauv daim duab kawg.

Kauj Ruam 5: Pib dua Pin thiab Tso Tawm

Cov kauj ruam tom ntej yog txuas tus pin 4 (Pib dua) rau tus pin 14 (Vcc) qhov no tau qhia hauv thawj daim duab. Qhov peb txuas Cov Khoom Siv (tus pin 5) rau 1K ohm resistor raws li qhia hauv daim duab thib ob. Kuv tso qhov qhwv qhwv raws li qhia hauv daim duab thib peb ua ntej txuas rau LED.

Kauj Ruam 6: Txuas LEDs

Txuas Anode (Ntev dua ceg) mus rau lwm qhov kawg ntawm 1K ohm resistor, thiab Cathode (luv dua) txhais ceg rau GND. Tom qab ntawd Txuas lwm 2 LED ua ke thaum ntsuas qhov nrug los ntawm sab hauv ntawm Ornament. Thaum kawg txuas lub xov tooj hluav taws xob tus pin 14 (Vcc rau liab) thiab tus pin 7 (GND rau dub) raws li qhia hauv daim duab thib ob. Tsis txhob hnov qab muab cov ntawv qhwv ua ntej txuas.

Kauj Ruam 7: Kuaj Circuit Court

Txuas lub roj teeb 9V rau hauv Circuit Court. Yog tias txhua yam mus tau zoo, LEDs yuav tsum pib ntsais muag. Nrog koj zoo siab koj tau ua nws. Qhov no yog qee yam kom txaus siab rau, koj tau tsim qhov zoo tshaj plaws multivibrator siv NE556.

Kauj Ruam 8: Ua kom tiav Daim Ntawv Qhia Hnub So

Tam sim no koj tuaj yeem tso lub Circuit Court rau hauv Ornament thiab lo rau sab saum toj, tsis txhob hnov qab sim nws dua ib zaug koj tau glued nws kom paub tseeb tias txhua yam tseem ua haujlwm.

Kauj Ruam 9: Dai nws rau tsob ntoo Christmas

Tam sim no koj tuaj yeem txaus siab dai nws rau koj tsob ntoo Christmas thiab txaus siab rau lub caij lom zem nrog koj qhov kev tsim txiaj.

Kev xav zaum kawg: NE556 suav nrog 2 NE555, hauv Circuit no peb tsuas yog siv ib qho NE555, nws zoo li yog pov tseg, yog li qhov nyuaj rau koj yog los tsim qhov thib ob Circuit Court siv tib IC.

Ua tsaug rau koj nyeem qhov no mus txog thaum kawg. Yog tias koj nyiam qhov Circuit no thov pov npav rau kuv, thiab mus saib kuv lub vev xaib thiab sau npe yuav nkag mus rau lwm yam kev sib tw yooj yim.
