CN5711 Driving LED yokhala ndi Arduino kapena Potentiometer
Momwe Mungayendetsere Led Ndi Arduino kapena Potentiometer (CN5711)
pa dariocose
Ndimakonda ma LED, makamaka azinthu zanga, monga kupanga miyuni ndi nyali zanjinga yanga.
Mu phunziro ili ndikufotokozerani momwe mungagwiritsire ntchito ma drive osavuta omwe amakwaniritsa zosowa zanga:
- Vin <5V kugwiritsa ntchito batri imodzi ya lithiamu kapena USB
- Kuthekera kusinthasintha kwapano ndi potentiometer kapena ndi microcontroller
- dera losavuta, zigawo zochepa ndi zolemba zazing'ono
Ndikukhulupirira kuti kalozera kakang'ono kameneka kadzakhala kothandiza kwa ogwiritsa ntchito ena!
Zothandizira:
Zigawo
- Module yoyendetsa ya LED
- Mphamvu iliyonse yoyendetsedwa (ndinagwiritsa ntchito 1 watt yofiira yokhala ndi mandala a 60 °)
- Battery kapena magetsi
- Breadboard
- Zigawo
Kwa mtundu wa diy:
- Chithunzi cha CN5711
- Potentiometer
- Bungwe la Prototype
- SOP8 kuti DIP8 pcb kapena SOP8 kuti DIP8 adaputala
Zida
- chitsulo soldering
- Screwdriver
Gawo 1: Datasheet
Miyezi ingapo yapitayo ndinapeza pa Aliexpress moduli yotsogolera yoyendetsa yomwe ili ndi CN5711 IC, yotsutsa komanso yotsutsa.
Zithunzi za CN5711
Kufotokozera Zazikulu:
Kufotokozera Zazikulu: CN5711 ndi dera lomwe lilipo pano lomwe likugwira ntchito kuchokera ku voliyumu yowonjezeratage wa 2.8V kuti 6V, nthawi zonse linanena bungwe panopa akhoza kukhazikitsidwa kwa 1.5A ndi resistor kunja. CN5711 ndi yabwino kuyendetsa ma LED. […] The CN5711 imatengera malamulo a kutentha m'malo moteteza kutentha, kuwongolera kutentha kumatha kupangitsa kuti LED ikhale yoyatsidwa mosalekeza ngati kutentha kozungulira kapena vol.tagndi dontho. […]
Mapulogalamu: Tochi, dalaivala wowala kwambiri wa LED, nyali zakutsogolo za LED, magetsi angozi ndi kuyatsa […]
Mawonekedwe: Opaleshoni Voltage Range: 2.8V mpaka 6V, On-chip Power MOSFET, Low Dropout Voltage: 0.37V @ 1.5A, LED Panopa mpaka 1.5A, Zolondola Pakalipano: ± 5%, Chip Temperature Regulation, Pa LED Current Protection [...] Pali mitundu itatu yogwiritsira ntchito IC iyi:
- Ndi chizindikiro cha PWM chogwiritsidwa ntchito mwachindunji pa pini ya CE, mafupipafupi a chizindikiro cha PWM ayenera kukhala osachepera 2KHz.
- Ndi chizindikiro chomveka chomwe chimagwiritsidwa ntchito pachipata cha NMOS (Chithunzi 4)
- Ndi potentiometer (Chithunzi 5)
Kugwiritsa ntchito chizindikiro cha PWM ndikosavuta kuyendetsa IC ndi microcontroller ngati Arduino, Esp32 ndi AtTiny85.
Kufotokozera Kwambiri
CN571 I ndi gawo laposachedwa lophatikizika lomwe likugwira ntchito kuchokera pakulowetsa voltage wa 2.8V kuti 6V, nthawi zonse linanena bungwe panopa akhoza kukhazikitsidwa kwa I.5A ndi resistor kunja. CN5711 ndi yabwino kuyendetsa LED. Mphamvu ya pa-chip MOSFET ndi block sensor yapano imachepetsa kwambiri kuchuluka kwa zigawo zakunja. CN5711 imatengera malamulo a kutentha m'malo moteteza kutentha, malamulo a kutentha amatha kuchititsa kuti LED ikhale yoyatsidwa mosalekeza ngati kutentha kwakukulu kapena kutentha kwakukulu.tagndi dontho. Zina zomwe zikuphatikizapo chip enable, ndi zina zotero. CN5711 imapezeka mu phukusi laling'ono lachidule la 8-pini (SOPS).

Chithunzi 3. CN5711 imayendetsa ma LED mu Parallel 
Chithunzi 4 Chizindikiro chomveka cha Dim LED
Njira 3: Potentiometer imagwiritsidwa ntchito kuchepetsa kuwala kwa LED monga momwe tawonetsera pa Chithunzi 5.
Chithunzi 5 Potentiometer Kuchepetsa LED
Khwerero 2: Yendetsani Led Ndi Yomangidwa mu Potentiometer
Ndikukhulupirira kuti mawaya amamveka bwino pazithunzi ndi makanema.
V1 >> buluu >> magetsi +
CE >>blue >> magetsi +
G >> imvi >> pansi
LED >> bulauni >> LED +
Kuti ndizitha kuyendetsa dera ndimagwiritsa ntchito magetsi otsika mtengo (opangidwa ndi magetsi akale a atx ndi ZK-4KX buck boost converter) . Ndinakhazikitsa voltage mpaka 4.2v kutengera batire imodzi ya lithiamu.
Monga tikuonera pavidiyoyi, mphamvu za dera zimachokera ku 30mA mpaka kupitirira 200mA

Kusintha kwapano kudzera mu resistor chosinthika.
Chonde gwiritsani ntchito screwdriver yoyenera kuti muzungulire pang'onopang'ono
Khwerero 3: Yendetsani Led Ndi Microcontroller
Kuti muwongolere dera ndi microcontroller ingolumikizani pini ya CE ku pini ya PWM ya microcontroller.
V1 >>blue >> magetsi +
CE >> wofiirira >> pwm pini
G >> imvi >> pansi
LED >> bulauni >> LED +
Kukhazikitsa kuzungulira kwa ntchito ku 0 (0%) LED idzazimitsa. Kuyika ntchito yozungulira ku 255 (100%) LED idzawunikira mwamphamvu kwambiri. Ndi mizere yochepa ya code tikhoza kusintha kuwala kwa LED.
Mugawoli mutha kutsitsa nambala yoyeserera ya Arduino, Esp32 ndi AtTiny85.
Arduino test kodi:
#define pinLed 3
#define led Off 0
#define led Pa 250 //255 ndiye kuchuluka kwa pwm
int mtengo = 0; //pwm mtengo
kukhazikitsa opanda kanthu () {
pinMode(pinLed, OUTPUT); //setto il pin pwm come uscita
}
kuzungulira () {
//kupenya
analogi Lembani (pinLed, led Off); // Chotsani LED
kuchedwa (1000);
// Dikirani kamphindi
analogi Lembani (pinLed, led On); // Yatsani mayendedwe
kuchedwa (1000);
// Dikirani kamphindi
analogi Lembani (pinLed, led Off); //…
kuchedwa (1000);
analogi Lembani (pinLed, led On);
kuchedwa (1000);
//mwam
chifukwa (mtengo = ledOn; mtengo> ledOff; mtengo -) {//chepetsa kuwala pochepetsa "mtengo"
analogi Lembani(pinLed, value);
kuchedwa (20);
}
chifukwa (mtengo = ledOff; mtengo <ledOn; mtengo ++) {//onjezani kuwala powonjezera "mtengo"
analogi Lembani(pinLed, value);
kuchedwa (20);
}
}

Khwerero 4: Diy Version
Ndinapanga mtundu wa diy wa module kutsatira muyezo wa datadata.
Ndidagwiritsa ntchito 50k potentiometer ngakhale deta imati "mtengo wapamwamba wa R-ISET ndi 30K ohm".
Monga mukuwonera kuti derali siloyera kwambiri…
Ndikadagwiritsa ntchito SOP8 kupita ku DIP8 pcb kapena SOP8 kupita ku DIP8 adaputala yozungulira yokongola kwambiri!
Ndikuyembekeza kugawana nawo gerber file posachedwa kuti mutha kugwiritsa ntchito.
Khwerero 5: Tikuwonani Posachedwa!
Chonde ndisiyireni malingaliro anu ndi ndemanga ndikuwonetsa zolakwika zaukadaulo ndi galamala!
Ndithandizeni ine ndi mapulojekiti anga pa ulalo uwu https://allmylinks.com/dariocose
Ntchito yabwino!
Ndinawona cholakwika chimodzi cha galamala chomwe chingayambitse chisokonezo. Pamapeto pa sitepe 2 mukuti:
"Monga tikuwonera muvidiyoyi, mphamvu zamagetsi kuchokera ku 30mAh kupita ku 200mAh"
Izi ziyenera kunena kuti "30 mA mpaka 200 mA."
Mawu akuti mAh amatanthauza "milliamps nthawi maola ndipo ndi muyeso wa mphamvu, osati muyeso wapano. Mamiliyoni khumi ndi asanuamps kwa 2 hours kapena 5 milliamps kwa maola 6 onse ndi 30 mAh.
Malangizo olembedwa bwino amatha!
Zikomo!
Mukunena zowona! Zikomo chifukwa chaupangiri wanu!
Ndikukonza nthawi yomweyo!
