2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30

Nov yog ncua sijhawm siv lub sijhawm 555 yooj yim. uas yuav ua kom muaj eg. kiv cua, lub teeb, lub cev muaj zog ua haujlwm rau lub sijhawm tau teev tseg tom qab qhov ua kom raug xaiv tau qhib. (piv txwv li khaws koj lub khoos phis tawj CPU khiav rau lwm 5 feeb kom txias tom qab lub pc tawm)

Mus yooj yim ntawm kuv qhov no yog kuv thawj tute: P Disclaimer: Kuv tsis muaj lub luag haujlwm rau ib qho teeb meem uas koj yuav ntsib nrog siv cov khoom no. yuav tsis muaj ib yam tab sis tsuas yog npog kuv lub nroog Yeiuxalees xwb: P

Kauj Ruam 1: Cheebtsam thiab Pcb

2 tus pin davhlau ya nyob twg thaiv *3 Capacitor (nyiam dua ceramic) = 10nf Electrolytic capacitor 220uf = 16v 1N4001 diode 555 Timer IC socket (8pin) DPDT relay (YUAV TSUM MUAJ QHOV TSEEM CEEB HEEV) = 12V N-channel MOSFET (nws txawv raws li txoj haujlwm) Resistor = 33k Resistor = 10k Resistor = 100k Resistor = 1k Resistor = 51R Potentiometer (PCB mount) = 1M PCB ntawm chav kawm lossis ntawv ci yog tias koj xav ntsuas ua ntej paub yog tias koj xav kom cov zis txuas nrog lub tshuab koj yuav xav tau sib txawv rau ib qho tau teev tseg thiab tseem yuav xav tau lwm lub diode los tiv thaiv nws, DC cov kiv cua hauv computer tsis muaj teeb meem tam sim no. xav nug kuv cov lus nug thiab mob ua qhov zoo tshaj los teb lawv rau koj. Nws nyob ntawm koj ntawm txoj kev twg uas koj xaiv kom tau txais koj lub Circuit Court, kuv tau siv txheej txheem kev nthuav tawm duab thiab veroboard, ob leeg ua haujlwm tau zoo, veroboard tau ntau dua compact tab sis nws tau ntxhov thiab qias neeg.

Kauj ruam 2: Circuit Court

ZOO TSHAJ PLAWS CIRCUIT DIAGRAM hauv qab R5 tsis yog 100K ITS 300K Tsuas yog Qub VERSION.

Kuv tsim thiab tsim cov kab hluav taws xob no kuv tus kheej nws tau teeb tsa rau tua lub kiv cua tom qab 6 feeb thaum lub khoos phis tawj kaw tab sis qhov no tuaj yeem hloov pauv yog tias koj hloov kho NC thiab TSIS Pins ntawm qhov txuas. Nws yuav tsum khiav los ntawm kwv yees li 1:20 feeb - 6 feeb. Kuv paub tom qab ntawd muaj 2 qhov tsis raug, 1 vim yog qhov txuas, kuv tau pom tias qhov kev xa tawm yog qhov kub heev, thaum lub zog xa hluav taws xob tau hloov pauv ntawm lub capacitor sab ntawm qhov txuas (ib txwm) yuav tsum ntaus NC (feem ntau kaw) ua ntej lwm sab kaw txwv tsis pub nws yuav tsis pib rau lub sijhawm thiab yuav hloov pauv yooj yim, kuv daws qhov teeb meem no ntawm kuv tus kheej los ntawm kev tshem lub npog ntawm qhov txuas thiab khoov tus pin NC yog li nws tau nyob ze rau ib qho. Lwm qhov teeb meem yog tias yog qhov ua rau raug rov qab los ntawm kev suav rov suav lub sijhawm yuav tsuas yog ncua thiab rov pib dua sai li sai tau txhais lub ntsiab lus nyob ntawm seb nws tau ua haujlwm ntev npaum li cas nws yuav txawv lub sijhawm ntxiv. Nco tseg: lub cav tuaj yeem hloov pauv los ntawm kev xa tawm (nrog lub diode) yog li qhov no tuaj yeem tswj hwm txhua yam koj xav tau, xws li ncua rau koj lub teeb taub hau lub tsheb lossis kiv cua hauv chav dej kom tshem cov pa tawm tom qab koj tawm mus, nws yog ib qho tseem ceeb heev Circuit Court thiab tuaj yeem siv rau ntau yam. "Cov duab PCB hauv qab no yog tsom rau kev nthuav tawm ncaj qha rau PCB"

Kauj Ruam 3: Xeem

kuv origionaly tau sim qhov no ntawm lub khob cij ua ntej yuav txav mus rau PCB tab sis yog tias koj ntseeg siab mus tom ntej. qhov kev ntsuas hauv qab no yog kuv li keeb kwm yav dhau los siv lub veroboard, lub ntsuas cua tau nyeem hauv Amps (0.67A) ntawm qhov ntau npaum li cas cov khoom siv dej txias tau kos, tab sis qhov txuas txuas tsis thign yog li koj yuav tsum muaj peev xwm khiav nws tawm yuav luag txhua yam (koj tuaj yeem hloov ua rau DPDT txuas nrog qhov qis dua ib qho lossis txawm tias siv IC qhov sib txuas raws li cov kab hluav taws xob kos me me tam sim no.

Cov vis dis aus yog tus qauv ntawm kuv cov cathodes txias. Kuv tau nyem ntau zaus los qhia tias qhov txuas txuas tau nyem thiab nws tsis cuam tshuam rau hauv Circuit Court.

Kauj Ruam 4: Cov Khoom Kawg

qhov khoom kawg yog PCB qis dua, nws ua haujlwm tau zoo thiab raws li tau npaj tseg, kuv tau nqes nws kom txuag chaw yog li kuv tuaj yeem tso rau hauv vaj tsev. Kuv tau ua qhov no raws li tsev kawm ntawv cov phiaj xwm phiaj xwm nws tseem tsis tau tiav tab sis kuv yuav hloov kho thaum tsim nyog.

txhua lo lus nug thiab mob sim kuv qhov zoo tshaj plaws los pab, yog kuv thawj tute yog li yuav tsis khoom yam tseeb. email rau kuv ntawm [email protected] lossis los ntawm kuv li kev qhia xa ntawv. thiab ua cov ntsiab lus zoo li TURBO TIMER HELP lossis qee yam kev cia siab zoo ib yam ua haujlwm rau koj ib yam li tau ua rau kuv.
