CN5711 Ke alakaʻi LED me Arduino a i ʻole Potentiometer
Pehea e hoʻokele ai i kahi alakaʻi me Arduino a i ʻole Potentiometer (CN5711)
na dariocose
Makemake au i nā LED, ʻoi aku no nā hana pilikino, e like me ka hana ʻana i nā lama a me nā kukui no kaʻu kaʻa.
Ma kēia kumu aʻo e wehewehe wau i ka hana o kahi led drive maʻalahi e kūpono i kaʻu mau pono:
- Vin <5V e hoʻohana i hoʻokahi pākahi lithium a i ʻole USB
- hiki ke hoʻololi i kēia manawa me kahi potentiometer a i ʻole me kahi microcontroller
- kaapuni maʻalahi, liʻiliʻi nā ʻāpana a me nā kapuaʻi liʻiliʻi
Manaʻo wau e pono kēia alakaʻi liʻiliʻi i nā mea hoʻohana ʻē aʻe!
Mea lako:
Nā ʻāpana
- Module alakaʻi alakaʻi
- ʻO kēlā me kēia mana i alakaʻi ʻia (ua hoʻohana wau i 1 watt ʻulaʻula alakaʻi me 60 ° lens)
- Batri a i ʻole ka mana
- Papa palaoa
- Nā ʻāpana
No ka mana diy:
- CN5711 IC
- ʻO ka Potentiometer
- Papa Kūlana
- SOP8 i DIP8 pcb a i ʻole SOP8 i DIP8 mea hoʻopili
Mea hana
- hao hao
- ʻōwili
KaʻAnuʻu 1: Pepa ʻikepili
I kekahi mau mahina i hala aku nei ua loaʻa iaʻu ma Aliexpress kahi module alakaʻi alakaʻi i haku ʻia me kahi IC CN5711, kahi pale a me kahi pale pale.
Mai ka ʻikepili CN5711:
Ka wehewehe nui:
ʻO ka wehewehe nui: ʻO ka CN5711 kahi kaapuni hoʻohui i kēia manawa e hana ana mai kahi vol inputtage o 2.8V a hiki i 6V, hiki ke hoʻonohonoho i ka manawa hoʻopuka mau i ka 1.5A me kahi pale kūwaho. He kūpono ka CN5711 no ka hoʻokele LED. [...] Hoʻohana ka CN5711 i ka hoʻoponopono wela ma mua o ka hana pale wela, hiki i ka hoʻoponopono wela ke hoʻohuli mau i ka LED i ke ʻano o ka wela ambient kiʻekiʻe a i ʻole ka vol kiʻekiʻe.tage kulu. […]
Nā noi: ʻO ke kukui uila, ke alakaʻi alakaʻi alakaʻi kiʻekiʻe, nā kukui LED, nā kukui pilikia a me nā kukui […]
Nā hiʻohiʻona: Hana Voltage Māhele: 2.8V a i 6V, MOSFET Mana Ma-chip, Voltage: 0.37V @ 1.5A, LED i kēia manawa a hiki i 1.5A, Hoʻopuka i kēia manawa pololei: ± 5%, Hoʻoponopono Temperature Chip, Ma luna o LED Current Protection [...] Aia nā ʻano hana 3 no kēia IC:
- Me kahi hōʻailona PWM i hoʻopili pololei ʻia i ka pine CE, ʻo ke alapine o ka hōʻailona PWM e emi iho ma mua o 2KHz
- Me kahi hōʻailona loiloi i hoʻopili ʻia i ka puka o kahi NMOS (Figure 4)
- Me ka potentiometer (Kiʻi 5)
Ke hoʻohana nei i ka hōʻailona PWM he mea maʻalahi loa ke hoʻokele i ka IC me kahi microcontroller e like me Arduino, Esp32 a me AtTiny85.
Ka wehewehe nui
ʻO ka CN571 I kahi kaapuni i hoʻohui ʻia i kēia manawa e hana ana mai kahi vol inputtage o ka 2.8V a hiki i ka 6V, hiki ke hoʻonohonoho i ka manawa hoʻopuka mau i I.5A me kahi pale pale waho. He kūpono ka CN5711 no ka hoʻokele LED. ʻO ka MOSFET mana on-chip a me ka poloka manaʻo o kēia manawa e hoʻemi nui i ka helu o ka helu o waho. Hoʻohana ka CN5711 i ka hoʻoponopono wela ma mua o ka hana pale wela, hiki i ka hoʻoponopono wela ke hoʻohuli mau i ka LED i ke ʻano o ka wela ambient kiʻekiʻe a i ʻole ka vol kiʻekiʻe.tage kulu. Loaʻa nā hiʻohiʻona ʻē aʻe i ka chip enable, a me nā mea ʻē aʻe. Loaʻa ka CN5711 i ka thermally-enhanced 8-pin small outline package (SOPS).
Nā hiʻohiʻona
- Hana Voltage Laulā: 2.8V a 6V
- MOSFET mana ma-chip
- Voltage: 0.37V @ 1.5A
- ʻO ke kukui LED a hiki i ka 1.5A
- Ka pololei o kēia manawa: * 5%
- Hooponopono Pumehana Chip
- Ma luna o ka pale ʻana i kēia manawa
- Kaulana Mahana Hana: – 40 V a +85
- Loaʻa iā SOPS Package
- Pb-noa, Rohs Compliant, Halogen Free
Nā noi
- kukui uila
- Keaukaha LED mālamalama kiʻekiʻe
- Nā kukui LED
- Nā kukui pilikia a me nā kukui
Kauoha Pin 
Kiʻi 3. CN5711 hoʻokuke i nā LED ma Parallel 
Kiʻi 4 He hōʻailona loiloi i Dim LED
Hanana 3: Hoʻohana ʻia kahi potentiometer e hoʻomāmā i ke kukui e like me ka hōʻike ʻana ma ke Kiʻi 5.
Kiʻi 5 He Potentiometer e hoʻomoe i ke kukui
KaʻAnuʻu Hana 2: E hoʻokele i ka Led me ka Potentiometer i kūkulu ʻia
Manaʻo wau ua maopopo ka wili i nā kiʻi a me nā wikiō.
V1 >> uliuli >> lako mana +
CE >>blue >> mana lako +
G >> hina >> lepo
LED >> ʻeleʻele >> alakaʻi +
No ka mana i ke kaapuni, ua hoʻohana au i kahi lako mana liʻiliʻi (i hana ʻia me kahi lako mana atx kahiko a me kahi ZK-4KX buck boost converter). Ua hoʻonoho wau i ka voltage i ka 4.2v e hoʻohālikelike i kahi pākahi lithium cell hoʻokahi.
E like me kā mākou e ʻike ai mai ke wikiō, ʻoi aku ka mana o ke kaapuni mai 30mA a ʻoi aku ma mua o 200mA

Hiki ke hoʻololi i kēia manawa ma o ka pale pale hiki ke hoʻololi.
E ʻoluʻolu e hoʻohana i ka screwdriver kūpono e hoʻololi mālie a lohi
KaʻAnuʻu Hana 3: E hoʻokele i ka Led me kahi Microcontroller
No ka mālama ʻana i ke kaapuni me kahi microcontroller e hoʻopili wale i ka pine CE i ka pine PWM o ka microcontroller.
V1 >>blue >> lako mana +
CE >> poni >> pine pwm
G >>hina >> lepo
LED >> ʻeleʻele >> alakaʻi +
E hoʻonoho i ka pōʻai hana i 0 (0%) e pio ka LED. Hoʻonohonoho i ka pōʻai hana i 255 (100%) e hoʻomālamalama ka LED i ka mana kiʻekiʻe. Me nā laina liʻiliʻi o ke code hiki iā mākou ke hoʻoponopono i ka mālamalama o ke LED.
Ma kēia ʻāpana hiki iā ʻoe ke hoʻoiho i kahi code hōʻike no Arduino, Esp32 a me AtTiny85.
Arduino hōʻike code:
#define pinLed 3
#define led Paʻa 0
#define led Ma 250 //255 ka nui pwm waiwai
int waiwai = 0; //pwm waiwai
ʻaʻohe hoʻonohonoho () {
pinMode(pinLed, OUTPUT); //setto il pin pwm come uscita
}
puka puka ʻole ( ) {
//mopō
Analog Kākau (pinLed, alakaʻi i waho); // Hoʻopau i ke alakaʻi
lohi(1000);
// E kali i kekona
Analog Kākau (pinLed, alakaʻi ʻia); // E hoʻā i ke alakaʻi
lohi(1000);
// E kali i kekona
Analog Kākau (pinLed, alakaʻi i waho); //…
lohi(1000);
Analog Kākau (pinLed, alakaʻi iā On);
lohi(1000);
//dimm
no ka (waiwai = ledOn; waiwai > ledOff; waiwai –) {//e hoemi i ke kukui ma ka hoemi ana i ka "waiwai"
Analog Kākau(pinLed, waiwai);
lohi(20);
}
no ka (waiwai = ledOff; waiwai < ledOn; waiwai ++) {/ //hoonui i ke kukui ma ka hoonui ana i ka "waiwai"
Analog Kākau(pinLed, waiwai);
lohi(20);
}
}

KaʻAnuʻu Hana 4: DIY Version
Ua hana au i kahi mana diy o ka module ma hope o ka circuit datasheet maʻamau.
Ua hoʻohana au i ka potentiometer 50k ʻoiai ke ʻōlelo nei ka ʻikepili "ʻo 30K ohm ka waiwai nui o R-ISET".
E like me kāu e ʻike ai ʻaʻole maʻemaʻe ke kaapuni…
Pono wau i hoʻohana iā SOP8 i DIP8 pcb a i ʻole SOP8 i DIP8 adapter no kahi kaapuni ʻoi aku ka nani!
Manaʻo wau e kaʻana like i kahi gerber file hiki koke iā ʻoe ke hoʻohana.
KaʻAnuʻu Hana 5: E ʻike koke iā ʻoe!
E ʻoluʻolu e waiho mai iaʻu i kāu mau manaʻo me kahi ʻōlelo a hōʻike i nā hewa ʻenehana a me ka grammatical!
E kākoʻo iaʻu a me kaʻu mau papahana ma kēia loulou https://allmylinks.com/dariocose
Hana maikaʻi!
Ua ʻike au i hoʻokahi hewa grammar technical i hiki ke hoʻohilahila. Ma ka hopena o ka ʻanuʻu 2 e ʻōlelo ʻoe:
"E like me kā mākou e ʻike ai mai ke wikiō, ʻoi aku ka mana o ke kaapuni mai 30mAh a ʻoi aku ma mua o 200mAh"
Pono e ʻōlelo "30 mA a i 200 mA."
ʻO ka huaʻōlelo mAh ʻo ia ka "miliamps mau hola a he ana ikehu, ʻaʻole he ana i kēia manawa. He ʻumikūmālima miliamps no 2 mau hola a i ʻole 5 miliamps no 6 mau hola he 30 mAh.
Hiki i ke aʻo kākau maikaʻi!
Mahalo!
Pololei ʻoe! Mahalo no kāu ʻōlelo aʻo!
Hoʻoponopono koke wau!
