Lub transistor yog cov cuab yeej siv hluav taws xob siv los txhawb lossis hloov pauv cov cim hluav taws xob thiab lub zog hluav taws xob. Nws yog tsim los ntawm cov khoom siv hluav taws xob feem ntau nrog tsawg kawg peb lub dav hlau rau kev txuas mus rau sab nrauv. Qhov hluav taws xob lossis qhov tam sim no siv rau ib khub ntawm transistor lub davhlau ya nyob twg tswj hwm qhov tam sim no los ntawm lwm khub ntawm lub davhlau ya nyob twg. Vim tias kev tswj hwm (tso zis) lub zog tuaj yeem siab dua li kev tswj hwm (tawm tswv yim) lub zog, lub transistor tuaj yeem ua lub teeb liab. Niaj hnub no, qee cov transistors tau ntim ib tus zuj zus, tab sis ntau yam ntxiv tau pom nyob hauv cov kab hluav taws xob sib txuas. Julius Edgar Lilienfeld patented transistor-effect transistor hauv 1926 tab sis nws tsis muaj peev xwm ua tau tiag tiag tsim cov cuab yeej ua haujlwm nyob rau lub sijhawm ntawd. Thawj qhov cuab yeej siv tau yog lub ntsiab lus hu rau transistor tau tsim hauv xyoo 1947 los ntawm Asmeskas tus kws tshawb fawb physicists John Bardeen, Walter Brattain, thiab William Shockley. Tus transistor tau hloov kho thaj chaw hluav taws xob, thiab nthuav txoj hauv kev rau cov xov tooj cua me me thiab pheej yig dua, cov laij lej, thiab khoos phis tawj, ntawm lwm yam. Lub transistor yog nyob rau ntawm cov npe ntawm IEEE cov ntsiab lus tseem ceeb hauv khoom siv hluav taws xob thiab Bardeen, Brattain, thiab Shockley tau sib koom 1956 Nobel Prize hauv Physics rau lawv qhov ua tiav. Feem ntau cov transistors yog ua los ntawm cov ntshiab silicon lossis germanium, tab sis qee qhov lwm yam khoom siv hluav taws xob kuj tseem tuaj yeem siv tau. Tus transistor yuav tsuas muaj ib hom kev them nqi thauj khoom, hauv thaj chaw cuam tshuam transistor, lossis tuaj yeem muaj ob hom kev them nqi hauv cov khoom siv bipolar hlws ris transistor. Piv nrog lub tshuab nqus tsev, cov transistors feem ntau me dua, thiab xav tau lub zog tsawg dua los ua haujlwm. Qee lub tshuab nqus tsev muaj qhov zoo dua transistors ntawm kev ua haujlwm siab heev lossis ua haujlwm siab. Ntau hom transistors tau ua rau tus qauv tshwj xeeb los ntawm ntau lub tuam txhab.

Tus naj npawb ntawm cov khoom sau hauv cov kab ntawv hais tias 1 rau txhua tus ntawm lawv, uas txhais tau tias koj xav tau 1 hauv Circuit Court. Nws tsis yog qhov koj yuav pom 1pc hauv Banggood.

Kauj Ruam 2: Kev Sib Txuas

Thawj qhov koj yuav tsum tau ua yog kawm paub siv lub khob cij kom raug. Koj yuav pom nws hauv YouTube. Thaum xub thawj, ntxig lub transistor mus rau lub khob cij. Nws muaj 3-pins, Emitter, Base, thiab Collector. Thaum lub tiaj tiaj ntawm 2N2222A NPN Transistor tau ntsib koj, tus pin sab laug yuav yog Emitter, nruab nrab ib puag puag, thiab sab xis yuav yog Tus Sau. Nco nws. Tom qab ntawd txuas lub LED Cathode (tus pin luv luv; tus pin tsis zoo) mus rau Tus Sau ntawm Transistor thiab muab nws tso rau hauv Anode (tus pin ntev dua; tus lej zoo) mus rau qhov chaw sib txuas ntawm lub khob cij. Tom qab ntawd txuas ib kawg ntawm tus tiv thaiv rau LED Anode thiab lwm qhov kawg rau qhov chaw sib txuas ntawm lub khob cij. Tom qab ntawd coj tus kov kov thiab koom nrog nws mus rau Tus Sau thiab mus rau qhov chaw sib txuas ntawm lub khob cij. Tom qab ntawd siv lwm qhov kov xov tooj thiab txuas nws mus rau Lub hauv paus thiab mus rau qhov chaw sib txuas ntawm lub khob cij. Tam sim no koom nrog lub roj teeb clip/txuas rau 9V roj teeb. Txuas nws VCC (cov hlau zoo; tej zaum yog liab) mus rau Resistor qhov txuas txuas thiab txuas hauv av (xaim tsis zoo; tej zaum yog Dub) rau Emitter ntawm Transistor. Koj tau ua tiav lawm. Nco ntsoov, tus lej tiv thaiv xim xim rau 1K OHM / 1000 OHM yog xim av, Dub, Liab, Kub. Siv 220 lossis 330 OHM resistors thaum txuas Buzzers. Saib resistor xim code daim duab/cov lus kom paub ntau ntxiv. Thiab nco ntsoov, xim xim rau 1K, 220, thiab 330 Ohm resistors sib txawv. Txheeb lawv hauv daim duab xim xim resistor.

Kauj Ruam 3: Tiav lawm - Cia Peb Xeem Nws

Kov ob lub xov hlau kov ua ke, thiab koj yuav pom LED yuav nyob twj ywm thaum kov, thiab tawm thaum koj tso koj tus ntiv tes. Nqa koj cov phooj ywg lossis ib tus neeg hauv tsev neeg. Kov ib lub xov hlau thiab qhia koj tus neeg sib tw kov lwm tus xaim thiab lawv kov tus neeg sib tw, thiab koj yuav pom qhov txuj ci. Qhov Circuit no ua tiav nrog LED, tab sis koj tuaj yeem siv lub suab nrov yog tias koj xav tau, lossis koj tuaj yeem txuas ob qho ntawm lawv ua ke. Hmoov zoo rau koj qhov kev sim.
