by dariocose
Ngiyawathanda ama-LED, ikakhulukazi amaphrojekthi omuntu siqu, njengokwenza amathoshi nezibani zebhayisikili lami.
Kulesi sifundo ngizochaza ukusebenza kwe-drive led elula ehlangabezana nezidingo zami:
- Vin < 5V ukuze usebenzise ibhethri ye-lithium eyodwa noma i-USB
- kungenzeka ukushintsha amandla amanje nge-potentiometer noma nge-microcontroller
- isifunda esilula, izingxenye ezimbalwa kanye nezinyathelo ezincane
Ngithemba ukuthi lo mhlahlandlela omncane uzoba usizo kwabanye abasebenzisi!
Izinsiza:

Isinyathelo 1: I-Datasheet
Ezinyangeni ezimbalwa ezedlule ngathola ku-Aliexpress imojula yomshayeli eholayo eyakhiwe i-CN5711 IC, i-resistor kanye ne-variable resistor.
Idatha ye-CN5711
Incazelo evamile:
Incazelo Evamile: I-CN5711 iyisekhethi ehlanganisiwe yomthethonqubo wamanje esebenza kusuka ku-voltage yokufakatage ka-2.8V ukuya ku-6V, okukhiphayo okungaguquki kwamanje kungasethwa kufike ku-1.5A nge-resistor yangaphandle. I-CN5711 ilungele ukushayela ama-LED. […] I-CN5711 yamukela ukulawulwa kwezinga lokushisa esikhundleni somsebenzi wokuvikela izinga lokushisa, ukulawulwa kwezinga lokushisa kungenza i-LED ivulwe ngokuqhubekayo uma izinga lokushisa le-ambient liphezulu noma ivolthi ephezulu.tage drop. […]
Izicelo: I-Flashlight, umshayeli okhanyayo we-LED, izibani zangaphambili ze-LED, izibani eziphuthumayo kanye nokukhanyisa [...]
Izici: I-Operating Voltage Ububanzi: 2.8V kuya ku-6V, On-chip Amandla MOSFET, Ivolumu Ephansi Yokuyekatage: 0.37V @ 1.5A, I-LED Yamanje ifika ku-1.5A, Ukunemba Kwamanje Kokukhiphayo: ± 5%, I-Chip Temperature Regulation, Over LED Current Protection [...] Kunezindlela ezi-3 zokusebenza zale IC:
- Ngesiginali ye-PWM esetshenziswe ngokuqondile kuphini ye-CE, imvamisa yesiginali ye-PWM kufanele ibe ngaphansi kuka-2KHz.
- Ngesiginali enengqondo esetshenziswa esangweni le-NMOS (Umfanekiso 4)
- Nge-potentiometer (Umfanekiso 5)
Ukusebenzisa isignali ye-PWM kulula kakhulu ukushayela i-IC ngesilawuli esincane esifana ne-Arduino, Esp32 ne-AtTiny85.
Incazelo evamile
I-CN571 I iyisekhethi yamanje ehlanganisiwe yomthethonqubo esebenza kusuka ku-voltage yokufakatage ka-2.8V ukuya ku-6V, okukhiphayo okungaguquki kungasethwa ku-I.5A ngesixhasi sangaphandle.

Umsebenzi Wezinsimbi 
Umfanekiso 3. I-CN5711 ishayela ama-LED ku-Parallel 
Umfanekiso 4 Isignali enengqondo eya ku-Dim LED
Indlela 3: I-potentiometer isetshenziselwa ukufiphalisa i-LED njengoba kuboniswe kuMfanekiso 5.
Umfanekiso 5 I-Potentiometer yokufiphalisa i-LED
Isinyathelo sesi-2: Shayela i-Led Nge-Potentiometer eyakhelwe ngaphakathi
Ngethemba ukuthi izintambo zicacile ezithombeni nakuvidiyo.
V1 >> blue >> ukunikezwa kwamandla +
CE >>blue >> ukunikezwa kwamandla +
G >> grey >> umhlabathi
I-LED >> ensundu >> eholele +
Ukuze nginike amandla isekethe ngasebenzisa ugesi oshibhile (owenziwe nge-atx yamandla endala kanye ne-ZK-4KX buck boost converter) . Setha ivolumutage kuya ku-4.2v ukulingisa ibhethri ye-lithium yeseli eyodwa.
Njengoba sibona kuvidiyo, amandla wesekethe ukusuka ku-30mA kuye kwangaphezulu kuka-200mA

Isimanje esilungisekayo nge-resistor elungisekayo.
Sicela usebenzise isikrudrayiva esifanelekile ukuze uphendukise ngobumnene nangokunensa
Isinyathelo sesi-3: Shayela i-Led Nge-Microcontroller
Ukuze ulawule isekethe nge-microcontroller vele uxhume iphinikhodi ye-CE kuphinikhodi ye-PWM ye-microcontroller.
V1 >>blue >> ukunikezwa kwamandla +
CE >> onsomi >> pwm pin
G >>grey >> umhlabathi
I-LED >> ensundu >> eholele +
Ukusetha umjikelezo womsebenzi ku-0 (0%) i-LED izocisha. Ukusetha umjikelezo wokusebenza ube ngu-255 (100%) i-LED izokhanya ngamandla amakhulu. Ngemigqa embalwa yekhodi singakwazi ukulungisa ukukhanya kwe-LED.
Kulesi sigaba ungalanda ikhodi yokuhlola ye-Arduino, Esp32 ne-AtTiny85.
Ikhodi yokuhlola ye-Arduino:
#define pinLed 3
#define led Off 0
#define led Ku-250 //255 inani eliphakeme le-pwm
inani le-int = 0; //pwm inani
ukusetha okungenalutho() {
i-pinMode(Iphinikhodi, I-OUTPUT); //setto il pin pwm woza uscita
}
iluphu engenalutho () {
//cwayiza
I-analog Bhala(i-pinLed, led Off); // Vala i-led
ukubambezeleka (1000);
// Linda umzuzwana
i-analog Bhala(i-pinLed, iholwa Phambili); / / Vula i-led
ukubambezeleka (1000);
// Linda umzuzwana
I-analog Bhala(i-pinLed, led Off); //…
ukubambezeleka (1000);
i-analog Bhala(i-pinLed, iholwa Phambili);
ukubambezeleka (1000);
//dimm
ku-(inani = ledOn; inani > i-ledOff; inani -) {//nciphisa ukukhanya ngokunciphisa "inani"
i-analog Bhala(iphiniwe, inani);
ukubambezeleka (20);
}
kokuthi (inani = ledOff; inani < ledOn; inani ++) {//khulisa ukukhanya ngokwandisa “inani”
i-analog Bhala(iphiniwe, inani);
ukubambezeleka (20);
}
}

Isinyathelo sesi-4: Inguqulo ye-Diy
Ngenze inguqulo ye-diy yemojuli ngokulandela isekethe yedatha evamile.
Ngisebenzise i-50k potentiometer nakuba idatha ithi “inani eliphezulu le-R-ISET ngu-30K ohm”.
Njengoba ubona isekethe ayihlanzekile kakhulu...
Bekufanele ngabe ngisebenzise i-SOP8 kuya ku-DIP8 pcb noma i-adaptha ye-SOP8 kuya ku-DIP8 ukuze ngibe nesekhethi ebukekayo!
Ngithemba ukwabelana nge-gerber file ngokushesha ongayisebenzisa.
Isinyathelo sesi-5: Sizokubona maduze!
Ngicela ungishiyele imibono yakho ngamazwana bese ubika amaphutha ezobuchwepheshe nawohlelo lolimi!
Ngisekele kanye namaphrojekthi ami kulesi sixhumanisi https://allmylinks.com/dariocose
Umsebenzi omuhle!
Ngibone iphutha elilodwa lohlelo lolimi olungadala ukudideka okuthile. Ekupheleni kwesinyathelo sesi-2 uthi:
“Njengoba sibona kuvidiyo, amandla esekethe asuka ku-30mAh aye ngaphezu kuka-200mAh”
Lokho kufanele kusho ukuthi "30 mA kuya ku-200 mA."
Igama elithi mAh lisho “milliamps izikhathi amahora futhi iyisilinganiso samandla, hhayi isilinganiso samanje. Amamiliyoni ayishumi nanhlanuamps amahora ama-2 noma ama-milli ama-5amps amahora angu-6 womabili angu-30 mAh.
Ibhalwe kahle iyala iyakwazi!
Siyabonga!
Ushaye khona! Siyabonga ngeseluleko sakho!
Ngilungisa ngokushesha!
