Taw qhia:

Nyob zoo cov phooj ywg, hnub no thaum lub sijhawm tsab xov xwm no peb tab tom tham txog txoj hauv kev los ua tus coj Flasher Circuit nrog LDR. Yog li, yeej, koj yuav hloov qhov ntsais nrawm nrog LDR lub tswm ciab.

Yog li qhov no feem ntau yog kev sib tw zoo tshaj plaws rau tus nyiam ua haujlwm. Yooj yim rau daim ntawv. koj yuav tsis xav tau PCBs rau kev tsim Circuit Court. koj tsuas yog yuav luag tag nrho cov khoom siv tau yooj yim thiab ua rau hauv Circuit Court.

Hom kev siv oscillation Circuit no feem ntau hu ua Stable multivariate. Cov kab hluav taws xob no tsis xav tau lwm qhov sab nraud lossis lwm qhov kev sib hloov rau kev khiav. Qhov oscillation tau ua los ntawm Transistor's thiab yog li ntawd cov capacitors thiab cov txheej txheem tsuas yog siv cov yoj, vim li ntawd, cov txiaj ntsig yuav mus zoo heev.

Lub voj voog no tsis xav tau kev txav sab nraud. Ntawm no Transistor tau hla ua ke. thiab yog li cov capacitors muaj ob lub xeev sib txawv. Yog tias ib lub capacitor nyob ntawm lwm lub capacitor yuav tawm. Lub Circuit Court ua haujlwm nrog lub network tawm tswv yim. yog vim li cas nws tseem hu ua Free Running Multivariator.

Qhov Circuit Court ua haujlwm li cas? nws yooj yim heev LDR tsim lub peev xwm faib tawm. Thaum LDR thiab yog li cov resistors tsim muaj peev xwm faib.

Tom qab ntawd qhov hnyav ntawm lub hnub ci tau siab dua ces LDR tus tiv thaiv tus nqi yuav qis dua. Thiab thaum qhov kev siv qis dua tus txheej txheem ces LDR ua raws li qhov tsis muaj zog tiv taus. Ntawm no rau lub tshuab hluav taws xob tau txuas nrog lawv ua haujlwm tau.

Yog tias tus capacitor 1 raug them ib zaug xwb ces Capacitor 2 yuav raug tso tawm. Qhov no ua haujlwm zoo ib yam ntawm flip flop teeb tsa. Lub capacitor 1 tawm los ntawm transistor 2 thiab yog li lub capacitor 2 tawm los ntawm transistor 1.

Thaum ib lub capacitor tsub lwm lub capacitor tawm. qhov no feem ntau yog ib qho xwm txheej ua ntu zus.

Khoom siv

Cov Cheeb Tsam Xav Tau:

BC547:

5MM LED:

10k Resistor:

18k Potentiometer:

Cov Cuab Yeej Xav Tau:

Soldering Iron:

Iron Stand:

Pliers Qhov ntswg:

Flux:

Kauj ruam 1:

Ua ntej, siv BC547 Transistor. Tom qab ntawd txuas 220R tus tiv thaiv nrog tus sau ntawm BC547 Transistor. Tom qab ntawd txuas 5 mm coj -ve nrog 220R resistor.

Kauj ruam 2:

Ua kom muaj qhov sib npaug sib npaug rau lwm lub sijhawm. Tom qab ntawd nqa LDR tom qab txuas ob Transistor puag nrog LDR. Tam sim no siv me ntsis ntawm cov xaim thiab txuas 2 tus emitter pins.

Kauj ruam 3:

Tam sim no coj 10k resistor ces hu rau ib qho kawg ntawm LED +Ve. Tam sim no siv lwm cov hlau ntawm Resistor thiab txuas nws nrog T1 Transistor lub hauv paus.

Ib yam nkaus, tam sim no txuas tus 18k resistor. Txuas ib kawg nrog LED +ve thiab lwm qhov kawg nrog T2 Transistor lub hauv paus.

Kauj ruam 4:

Tam sim no txuas cov capacitors thaum lub sijhawm no raws li qhia hauv daim duab. paub meej tias koj tsis luv Ib yam dab tsi hauv Circuit Court. Txwv tsis pub, LED Flasher Circuit nrog LDR yuav tsis ua haujlwm.

Txuas lub 9v roj teeb +ve hlau nrog LED +ve thiab txuas -v hlau nrog Transistor's Emitter tus pin.

Kauj ruam 5:

Tam sim no txuas lub Circuit nrog 9v roj teeb ces koj yuav pom lub Circuit yuav ua haujlwm zoo. Tom ntej no nqa lub teeb qhov hnyav los ze rau hauv Circuit Court tom qab ntawd koj yuav pom tias lub teeb ntsais coj mus yuav nrawm dua thiab yog tias koj tab tom noj tshav ntuj nyob deb ntawm LDR ces koj yuav pom tias LED ntsais muag yuav qeeb.

Kauj Ruam 6: Daim duab Circuit Court

Nco tseg:

Koj yuav tsum tsis txhob luv-Circuit Court ib qho ntawm Transistors. Txuas tus Transistor tus pin raws li qhia hauv daim duab. Yog tias koj tsim ib qho yuam kev ces yuav muaj qhov ua tau zoo ntawm Magic Smoke. Tsis muaj leej twg nyiam haus luam yeeb los ntawm Circuit Court. Yog li xyuam xim thaum ua qhov Circuit Court.

Xaus:

Txhua qhov, LED Flasher Circuit nrog LDR yuav yog qhov haujlwm zoo rau cov pib tshiab. thiab yog li ntawd lub Circuit Court yog qhov ncaj los tsim. Thiab nrog txhua qhov yooj yim txhua qhov khoom siv uas txhua tus tuaj yeem ua hluav taws xob hauv tsev. Yog li ntawd yog vim li cas cov phiaj xwm tseem ceeb heev rau Hobbyists. Koj kuj tseem tuaj yeem nyeem lwm tsab xov xwm hais txog Kev Siv Hluav Taws Xob Yooj Yim Qhov no feem ntau kuj yog qhov yooj yim los tsim.
