Hipanga 1: Rauraraunga
I etahi marama kua pahure ake nei ka kitea e au i runga i a Aliexpress tetahi kōwae taraiwa arataki i tito he IC CN5711, he parenga me tetahi parenga rereke.
Mai i nga papaaarangi CN5711:
Whakaahuatanga Whanui:
Whakamaramatanga Whanui: Ko te CN5711 he ara iahiko whakauru o naianei e whakahaere ana mai i te voli whakaurutage o 2.8V ki 6V, ka taea te whakarite i te naianei putanga tonu ki te 1.5A me te parenga o waho. Ko te CN5711 he pai mo te taraiwa LED. […] Ka whakamahia e te CN5711 te ture pāmahana hei utu mo te mahi whakamarumaru o te pāmahana, ka taea e te ture pāmahana te huri tonu i te LED mena he nui te pāmahana ambient, he voli teitei ranei.tage taka. […]
Nga tono: Ko te rama rama, te kaiarataki rama rama, rama rama rama, rama ohorere me te rama […]
Āhuatanga: Mahinga Mahi Voltage Awhe: 2.8V ki te 6V, Mosfet Power On-chip, Puawai Whakataka Ititage: 0.37V @ 1.5A, LED Naianei ki runga ki te 1.5A, Putanga Tika o naianei: ± 5%, Whakaritea Te Maamaa Tipi, Neke atu i te Tiaki o Naianei […] E 3 nga momo mahi mo tenei IC:
- Ma te tohu PWM e tika ana ki te pine CE, me iti iho te auau o te tohu PWM i te 2KHz
- Ma te tohu arorau ka tukuna ki te kuaha o te NMOS (Whakaahua 4)
- Me te potentiometer (Whakaahua 5)
Ma te whakamahi i te tohu PWM he tino ngawari ki te taraiwa i te IC me te microcontroller rite Arduino, Esp32 me AtTiny85.
Whakaahuatanga Whanui
Ko te CN571 I he ara iahiko whakauru o naianei e whakahaere ana mai i te voli whakaurutage o 2.8V ki 6V, ka taea te whakarite i te naianei putanga tonu ki te I.5A me te parenga o waho. Ko te CN5711 he pai mo te taraiwa LED. Ko te MOSFET mana maramara me te paraka mohio o naianei ka tino whakaiti i te maha o nga waahanga o waho. Ko te CN5711 te whakamahi i te ture pāmahana hei utu mo te mahi tiaki i te pāmahana, ka taea e te ture pāmahana te huri tonu i te LED mena he nui te pāmahana ambient, he voli teitei ranei.tage taka. Ko etahi atu ahuatanga ko te mahi maramara, me etahi atu. Kei te waatea te CN5711 i roto i te kete whakahuahua iti (SOPS) kua whakakaha-a-waariki.

Pin Mahi 
Whakaahua 3. Ka peia e CN5711 nga rama i roto i te Whakarara 
Whakaahua 4 He tohu arorau ki te Dim LED
Tikanga 3: Ka whakamahia he potentiometer ki te atarua i te LED pera i te Whakaaturanga 5.
Whakaaturanga 5 He Potentiometer hei Whakakore i te LED
Hipanga 2: Peia te Led Me te Potentiometer Hangaia
Kei te tumanako ahau kei te marama te waea i nga whakaahua me te ataata.
V1 >> puru >> tuku hiko +
CE >>puru >> supply hiko +
G >> hina >> whenua
LED >> parauri >> arahina +
Hei whakakaha i te ara iahiko i whakamahia e ahau he toha hiko iti (i hangaia me te toha hiko atx tawhito me te kaitahuri ZK-4KX buck boost converter) . I whakaturia e ahau te voltage ki te 4.2v ki te whakatairite i te pākahiko lithium pūtau kotahi.
Ka kite tatou mai i te ataata, ka kaha te hikoi mai i te 30mA ki te neke atu i te 200mA
https://youtu.be/kLZUsOy_Opg 
Naianei ka taea te whakarite na roto i te parenga ka taea te whakarite.
Tena koa whakamahia te huriwiri e tika ana hei huri marie me te ata hurihuri
Hipanga 3: Peia te Led Ma te Microcontroller
Hei whakahaere i te ara iahiko me te microcontroller hono noa te pine CE ki te pine PWM o te microcontroller.
V1 >>puru >> supply hiko +
CE >> papura >> pwm pine
G >>hina >> whenua
LED >> parauri >> arahina +
Ka whakatauhia te huringa mahi ki te 0 (0%) ka weto te LED. Ko te whakarite i te huringa mahi ki te 255 (100%) ka marama te LED i te mana teitei. Ma etahi rarangi waehere ka taea e tatou te whakatika i te kanapa o te LED.
I tenei waahanga ka taea e koe te tango i tetahi waehere whakamatautau mo Arduino, Esp32 me AtTiny85.
Waehere whakamatautau Arduino:
#tautuhia te pinLed 3
#define arahina Weto 0
#define led I te 250 //255 te uara pwm teitei
int uara = 0 ; //pwm uara
kore te tatūnga() {
PinMode(pinLed, OUTPUT); //setto il pin pwm come uscita
}
porowhita kore ( ) {
//kinamo
tairitenga Tuhia(pinLed, arahina Weto); // Whakawetohia te arahi
whakaroa(1000);
// Taria he tuarua
tairitenga Tuhia(pinLed, arahina Ki); // Whakakāhia te arahina
whakaroa(1000);
// Taria he tuarua
tairitenga Tuhia(pinLed, arahina Weto); //…
whakaroa(1000);
tairitenga Tuhia(pinLed, arahina Ki);
whakaroa(1000);
//marumaru
mo te (uara = ledOn; uara > ledOff; uara –) {//whakahekea te rama ma te whakaheke i te “uara”
tairitenga Tuhia(pinLed, uara);
whakaroa(20);
}
hoki (uara = ledOff; uara < ledOn; uara ++) {/ //whakanuia te rama ma te whakanui ake i te "uara"
tairitenga Tuhia(pinLed, uara);
whakaroa(20);
}
}

Hipanga 4: Putanga DIY
I hanga e ahau he putanga a-ringa o te kōwae e whai ana i te ara iahiko raraunga paerewa.
I whakamahia e ahau he potentiometer 50k ahakoa e kii ana te pepa raraunga ko te "30K ohm te uara teitei o te R-ISET".
Ka kite koe kaore i te tino ma te ara iahiko…
Me whakamahi ahau i te SOP8 ki te DIP8 pcb, te SOP8 ranei ki te DIP8 urutau mo te ara iahiko huatau ake!
Kei te tumanako ahau ki te tiri i tetahi gerber file hohoro ka taea e koe te whakamahi.
Hipanga 5: Ka kite wawe koe!
Tena koa waiho mai o whakaaro me te korero me te ripoata i nga hapa hangarau me te wetereo!
Tautokohia ahau me aku kaupapa i tenei hononga https://allmylinks.com/dariocose
He pai te mahi!
I kite ahau i tetahi hapa wetereo hangarau ka raru pea. I te mutunga o te taahiraa 2 ka kii koe:
"Kei te kite tatou mai i te riipene whakaata, ka kaha te hikoi mai i te 30mAh ki te neke atu i te 200mAh"
Me kii "30 mA ki te 200 mA."
Ko te kupu mAh te tikanga "milliamps ngā hāora, ā, he inenga pūngao, ehara i te ine o nāianei. Tekau ma rima miriamps mo te 2 haora, 5 milli raneiamps mo nga haora 6 he 30 mAh e rua.
He pai te tuhi tohutohu ka taea!
Mihi!
Ka tika koe! Mauruuru mo to tohutohu!
Ka whakatika tonu ahau!
