Hauv cov lus qhia no kuv tau sau tseg yuav ua li cas thiaj tsim lub cim LED nrog qhov tsaus ntuj / lub teeb pom kev zoo thiab PWM dimmer Circuit tsim hauv.
Kuv tau txais kev lom zem dhau Christmas thiab sib koom ua ke txoj haujlwm nrawm tau tshoov siab los ntawm youtube intro video intro's rau "GreatScott!". Kuv fancied tso kuv tus kheej lub npe nyob rau hauv teeb, tab sis kuv xav soldering 150+ LED's nyob rau hauv parallel tsis yog qhov nyuaj, yog li kuv xav tias kuv yuav ua rau nws me ntsis nthuav.
Kuv cov cim LED muaj qhov tsaus ntuj/pom lub teeb pom kev zoo kom hloov mus thaum hmo ntuj thiab tua thaum nruab hnub. Kuv kuj tom qab ntxiv PWM Circuit kom kho lub teeb ci ci LED (LED's Kuv muaj hauv kuv lub thoob khib nyiab tau dhau los ua qhov ci ntsa iab: -S). Feem ntau ntawm qhov kev tsim no yog los ntawm cov khoom uas kuv twb muaj ntau dua li nrhiav cov khoom tshiab kom txuag tau nyiaj, yog li ua ntej koj nug yog vim li cas kuv thiaj siv X tivthaiv tsis yog Y …… tam sim no koj paub:-)
Kauj Ruam 1: Lub Tswv Yim Tswv Yim
Muaj ntau txoj hauv kev sib txawv lub teeb/tsaus nti tuaj yeem tsim tau, feem ntau txoj hauv kev siv ib qho ntawm cov kab hauv qab no (Txhua qhov peb siv LDR lossis lub teeb nyob ntawm tus tiv thaiv ntawm nws cov tswv yim):
- 555 lub sijhawm nrog transistor ntawm tus pin 3
- LDR ua ib feem ntawm qhov faib hluav taws xob uas ua rau NPN transistor
- Ib qho kev sib piv voltage (op-amp / comparator IC)
Txij li thaum kuv tau muaj ntau yam sib txawv op-amp's thiab cov sib piv hauv kuv qhov chaw tso rau hauv kuv tau txiav txim siab siv LM311. Tus sib piv yooj yim sib piv cov khoom siv hluav taws xob ntawm nws cov tswv yim. Cov zis tawm siab thaum cov tswv yim zoo ib yam/ntau dua, thiab lossis qis dua thaum ib lub tswv yim qis dua lwm qhov. Hauv kuv qhov xwm txheej thaum LDR qhov hluav taws xob siab dua qhov ntsuas hluav taws xob teeb tsa los ntawm lub zog ntsuas hluav taws xob, cov zis raug rub siab, ua kom muaj kev sib txuas me me, uas ua rau kom pom kev ci ntsa iab LED. Ib lub tshuab hluav taws xob tau muab tso rau hauv Circuit Court txhawm rau tiv thaiv kev hloov pauv sai ntawm cov khoom xa tawm thaum qhov hluav taws xob nkag tau oscillating saum toj thiab qis dua qhov ntsuas hluav taws xob. MOSFET tuaj yeem siv tau ntawm no tab sis ntxiv kuv muaj cov khoom me me tso rau sab laug kom siv yog li kuv siv ib qho ntawm qhov ntawd.
Txog rau PWM Circuit kuv tau siv qhov qub 555 timer sib txawv qhov hluav taws xob mus rau LED's (saib daim duab txuas nrog).
Faj seeb: Hauv PWM schematic Rload yog LED Matrix koj xav tswj, hauv qhov ci ci teeb pom kev zoo Rload yog thev naus laus zis PWM Circuit hauv qhov no, tab sis koj tuaj yeem hloov pauv ncaj qha yog tias koj nyiam.
Kauj Ruam 2: Tsim Kev Tshawb Fawb Circuit Court
Los ntawm cov duab kuv tau tsim cov kev sib tw ntawm ob daim ntawv sib cais thiab sim pib siv ib qho LED. Sab tes xis yog qhov tsaus/lub teeb pom kev, thiab sab tes laug yog PWM Circuit. Lub ntsuas hluav taws xob ntsuas hluav taws xob hloov pauv tag nrho Circuit Court qhib/kaw thiab PWM hloov kho qhov hluav taws xob rau LED matrix.
Kuv lub hom phiaj yog kom tshem tawm 5V, 1A lub xov tooj ntawm tes them los ntawm lub micro usb breakout txuas. Lub Circuit Court tau hloov pauv sai heev ze rau nws qhov hloov pauv (tshwj xeeb thaum tsaus ntuj thaum lub teeb pom kev yog qhov nruab nrab nruab nrab) yog li kuv tau tso qhov tsis tsim nyog loj 2200uF capacitor hla lub transistor los tuav qhov hloov pauv thaum lub zog poob. Nyob ntawm seb tus nqi tam sim no koj lub dab dej puas yuav txiav txim siab nws muaj peev xwm tiv taus thiab yog li ua ib feem ntawm RC network nrog lub capacitor. Lub sijhawm tus capacitor tuav tus nqi hluav taws xob tuaj yeem pom siv lub sijhawm tas li cov qauv t = R x C. Koj yuav tsum muaj peev xwm suav tus nqi tsim nyog siv tus qauv no. Hauv qhov tseeb koj yuav tsum khaws cov khoom ntim khoom siv hluav taws xob zoo li cov khoom siv hluav taws xob tsawg li sai tau kom txo qis kev siv hluav taws xob tsis tsim nyog.
Kuv siv Loch-Master rau qhov chaw tawm lub npe Kuv xav kom muab kuv lub 5mm LED los rau. Kuv nyiam siv 2.54mm pitch longitudinal strip-board (aka veroboard). Txhua lub LED tau muag ua ke (qhov no tsis yog kev coj ua zoo, qhov uas ua tau koj yuav tsum txwv qhov tam sim no rau txhua tus neeg LED nrog cais tus neeg tawm tsam).
Kauj ruam 3: Sib dhos
Cov kauj ruam hauv qab no suav nrog qhov tsis tsim nyog ntawm cov kua nplaum kub. Nws yog qhov zoo tshaj rau cov neeg tub nkeeg li kuv uas tsuas yog xav koom nrog yam sai.
Thaum kuv tau npaj lub npe tawm siv Loch-master kuv tau siv tag nrho cov LEDs ua ke. Ob qho PWM thiab lub teeb ci ci tau muab muag rau ntawm ib daim ntawv ntawm kab txaij. LDR tau sib cais los ntawm cov kab hluav taws xob tseem ceeb ntawm kev ya mus kom lub sensor nws tus kheej tuaj yeem ua rau lub qhov nyob ntawm lub hauv ntej ntawm lub bezel. Cov no tau teeb tsa mus rau ib qho ntawm insulating PVC, uas yog tom qab ntawd nws tus kheej tau glued mus rau tom qab ntawm LED matrix.
Paub txog qhov ntev ntawm LED matrix los ntawm Loch-Master Kuv tau ua lub PVC dub bezel kom nyob ib puag ncig LED matrix thiab ua kom nws zoo nkauj. Kuv tau ua tus qauv kom haum rau nplooj ntawv A4 yog li qhov no tuaj yeem luam tawm ntawm daim ntawv thiab muab tso rau ntau dua 5mm dub foamboard. Tom qab ntawd kuv tau kaw cov qauv siv daim npog ntsej muag thiab ua tib zoo txiav tawm nruab nrab thiab cov ntug nrog rab riam. Kuv kuj tau ua qhov sib piv yam tsis muaj kev txiav tawm hauv nruab nrab rau nraub qaum. Ib puag ncig tau muab rau LED matrix thiab yooj yim glued rau. Ob lub voj voog tom qab ntawd tau lo rau sab nraum qab ntawm daim kab xev LED (ceeb toom tias cov no tau sib cais siv qee qhov PVC).
Thaum kawg lub vaj huam sib luag tom qab tau ntxiv los ntawm kev siv M3 cov ntsia hlau tso los ntawm lub hauv ntej thiab cov spacers dub (sawv ntsug tawm) tsau rau hauv lawv. Qhov no tau tso cai rau lub vaj huam sib luag rov qab rau xov rau saum thiab tuav hauv qhov chaw los ntawm rau M3 txiv ntseej thiab tshuab ntxhua khaub ncaws.
Kauj ruam 4: Txaus siab rau
Kuv vam tias koj txaus siab rau txoj haujlwm lis xaus lis xaus no. Muaj ntau chav rau kev txhim kho ntawm qhov no vim nws tsuas yog kev lom zem me ntsis, tab sis kuv vam tias kuv tau tshoov koj siab los ua koj tus kheej. Koj tuaj yeem siv tsuas yog PWM Circuit Court ntawm nws tus kheej thiab sib txawv qhov ci ntawm LED's nyob ntawm seb lub teeb nyob ntawm seb lub sijhawm nruab hnub.
Cov txheej txheem hauv Circuit tuaj yeem siv rau lwm yam txias xws li ntsuas cua sov (sib pauv LDR nrog lub ntsuas cua) lossis lub cev muaj zog sib txawv tswj nrog PWM Circuit.
