Kev kho lub teeb xiav tuaj yeem siv los txhim kho kev xav, txhim kho kev pw tsaug zog, kho lub dav hlau lag luam, kho lub sijhawm pw, thiab txhawb zog. Kev kho teeb pom kev zoo pab cov tub ntxhais kawm ntawv uas pib kawm ntawv ntxov thaum nws tseem tsaus ntuj. Qhov no tuaj yeem haum hauv koj lub hnab ev ntawv, dimmable, muaj lub sijhawm hloov kho tau, thiab nws tsis raug nqi ntau dhau los tsim. Siv nws thaum sawv ntxov tuaj yeem hloov koj mus rau hauv cov noog thaum ntxov thiab siv nws thaum yav tsaus ntuj tuaj yeem tig koj mus rau hauv cov noog hmo ntuj. Koj tuaj yeem siv nws thaum caij tsheb npav.

Kauj ruam 2: Circuit Court

Hauv kab lus no, kuv tau teeb tsa ATTiny85 ua lub sijhawm thiab PWM lub teeb dimmer. Q1 yog qhov hloov pauv rau lub zog nws. Lub zog loj IRFZ44N ua haujlwm rau lub hloov pauv inrush tam sim no. D1 tiv thaiv Q1 qis zog los ntawm kev tiv thaiv nws lub qhov rooj hluav taws xob los ntawm ntau dua 20V. R5 tiv thaiv Q2 los ntawm cov kab hluav taws xob poob qis los ntawm kev tso cai me me ntws los ntawm lawv, khaws Vds ntawm Q2 los ntawm ntau dua 30V. Koj yuav pom tias txawm tias thaum lub sijhawm timer tawm, lawv yuav dimly lit. LM2577 step-up converter khaws cov LED teeb ntawm 30-35V thiab tso cai rau peb siv ntau yam khoom siv hluav taws xob. Nws tuaj yeem hloov kho kom qis dua qhov hluav taws xob yog tias tam sim no siab dhau lossis koj xav tau lub teeb tsawg dua. Kuv tau tso tawm qhov hluav taws xob teeb tsa rau 32.3V, thiab cov tiv thaiv tau ntawm 1.5V, muab 15mA. Lub DC jack tau xaim tso cai siv lub zog thib ob los ntawm kev txuas nws tus pin nruab nrab mus rau lub roj teeb hauv av, tus pin sab nraud rau lub hwj chim hauv av.

Kauj Ruam 3: Kos rau ATtiny85

Cov txheej txheem kos duab no ATtiny85 rau hauv ob qho tib si PWM dimmer thiab teeb lub teeb. VR1 teeb tsa qib ci ci ntawm LED teeb hauv 255 cov kauj ruam, thiab VR2 teeb tsa lub sijhawm kho ntawm 0 txog 60 feeb, rov ua dua txhua teev, uas yuav zoo dua yog tias koj ua haujlwm hmo ntuj. Koj yuav tsum tau kho qhov teeb tsa ua ntej koj qhib nws txij li ATtiny85 nyeem nws tsuas yog thaum pib. Yog tias koj xav tau qhov sib txawv ntawm/tawm lub sijhawm, hloov tus nqi ntawm periodMin. Koj tuaj yeem kawm paub yuav ua haujlwm li cas rau ATtiny85 ntawm no: https://www.instructables.com/id/Program-an-ATtiny-with-Arduino/ int LEDPin = 0; // PWM cov tswv yim txuas nrog tus lej digital 0 int brightPin = 2; // ci ntsa iab potentiometer txuas nrog analog pin 2 int timerPin = 3; // timer potentiometer txuas nrog analog pin 3 ntev periodMin = 60; // teeb tsa lub sijhawm nyob hauv feeb ntev periodSec = periodMin*60; // suav lub sijhawm nyob hauv vib nas this ntev = 1000*periodSec; // suav lub sijhawm nyob hauv milliseconds tsis muaj teeb meem teeb tsa () {pinMode (LEDPin, OUTPUT); // teeb tus pin raws li kev tso tawm} void loop () {int val1 = analogRead (brightPin); // nyeem qhov teeb tsa qhov teeb tsa potentiometer analogWrite (LEDPin, val1 / 4); // teeb tsa qib ci ci ntawm LED teeb ntawm 0 txog 255 int val2 = analogRead (timerPin); // nyeem lub timer teeb tsa lub hwj chim ntev ntawm = (lub sijhawm*val2/1023); // ntawm lub sijhawm hauv milliseconds ntev tawm = (lub sijhawm-rau); // tawm sijhawm hauv milliseconds ncua (ntawm); analogWrite (LEDPin, 0); // teeb ci ci ntawm LED teeb rau 0 ncua (tawm); }

Kauj Ruam 4: Cov Ntaub Ntawv ExpressPCB

Kuv tsim cov phiaj xwm hluav taws xob siv ExpressPCB thiab suav nrog cov ntaub ntawv luam tawm tag nrho nplooj ntawv. Thov koj xav hloov kho tus qauv yog tias koj muaj pob khoom sib txawv. Koj tuaj yeem rub tawm ExpressPCB los ntawm lub vev xaib no: https://www.expresspcb.com/ExpressPCBHtm/Download.htm Rau Linux, koj tuaj yeem nruab WINE los siv qhov program.
