LED snowman kwa aliyense

N'zovuta kulingalira nyengo yozizira popanda matalala. Ndipo zovuta kwambiri - popanda snowman. Chifukwa chake, pamene tikudikirira chipale chofewa, tikupangira kupanga Snowman kuchokera ku ma LED.

Kujambula munthu wa chipale chofewa ndi chizindikiro cha nyengo yozizira, koma kwa ambiri aife timagwirizanitsa ndi maholide omwe akubwera, misonkhano ya mabanja ndi kukongoletsa mtengo wa Khirisimasi, momwe mungathe kupachika gadget yoperekedwa ngati imodzi mwa zokongoletsera. Itha kukhalanso mphatso yabwino kwa mwana yemwe tikufuna kuyika "electronic bug". Wopereka chipale chofewa ali ndi mawonekedwe okongola, kotero iye adzawakonda.

Kusapezeka kwa dera lililonse lophatikizika kumapangitsa kuti mawonekedwewo akhale abwino kwa mainjiniya amagetsi oyambira. Komabe, palibe chomwe chimalepheretsa akulu kusonkhanitsa munthu wokongola, wowoneka bwino wa chipale chofewa, akumaona ngati zosangalatsa mu nthawi yawo yopuma pantchito ya tsiku ndi tsiku.

Kufotokozera kamangidwe

Chithunzi chosavuta cha dera chingapezeke pa chithunzi 1. Ili ndi unyolo wokha wa ma LED akuthwanima anayi olumikizidwa mofananira, pomwe gwero lamagetsi limalumikizidwa mu mawonekedwe a mabatire awiri a 1,5V.

1. Chithunzi chojambula cha snowman wa LED

Kuti magwiridwe antchito azitha, pali chosinthira SW1 mugawo lamagetsi. Kuthwanima kwa LED, kuwonjezera pa kapangidwe ka kuunikira, kumakhala ndi kachitidwe kakang'ono kamene kamawongolera, kotero kuti kangathe (ndipo kayenera) kuyendetsedwa mwachindunji, kudutsa chopinga chomwe chimachepetsa mphamvu yake yamakono. Ma LED akuthwanima amatha kudziwika ndi malo amdima mkati mwake, omwe amawoneka bwino chithunzi 1. Chifukwa cha kusiyana kwakukulu kwa magawo amkati a ma jenereta a ma LED awa, aliyense wa iwo amawalira mosiyanasiyana, pafupipafupi. Mafupipafupi awa ali mumtundu wa 1,5-3 Hz ndipo makamaka zimadalira mphamvu yamagetsi. LED1 ndi yofiira ndipo imatsanzira mphuno ya "karoti" ya chipale chofewa, pamenepa imakhala yojambula pang'ono. M'malo mwa mabatani akuda "malasha" pamimba - ma LED atatu abuluu 2 ... 4.

Kuyika ndi kusintha

Chitsanzo cha PCB chikuphatikizidwa chithunzi 2. Sichifuna luso lapadera kuti asonkhanitse.

Ntchito iyenera kuyamba ndi soldering switch SW1. Idapangidwa kuti ikhale yokwera pamwamba (SMD) koma izi zisakhale zovuta ngakhale kwa omwe angoyamba kumene kumagetsi.

Kuti zinthu zikhale zosavuta, ikani dontho la malata pa imodzi mwa mfundo zisanu ndi imodzi za solder za SW1, kenaka gwiritsani ntchito zitsulo kuti muyike batani m'malo mwake ndikusungunula solder yomwe yagwiritsidwapo kale ndi chitsulo chosungunuka. Chophimba chokonzekera motere sichingasunthe, kukulolani kuti muzitha kugulitsa mayendedwe ake ena mosavuta.

Chotsatira cha msonkhano ndikugulitsa ma LED. Pa bolodi kuchokera kumbali ya soldering pali contour yawo - iyenera kufanana ndi kudula pa diode yomwe imayikidwa mu mabowo okwera.

Kuonjezera zenizeni ku khalidwe lathu la "chipale chofewa", ndi bwino kumupangira tsache, lomwe lingathe kulumikizidwa bwino kuchokera ku mbale ya siliva yomwe ili m'kati mwake ndikugulitsidwa ku imodzi mwa minda yamatabwa m'mphepete mwa bolodi losindikizidwa. . Mtundu umodzi wa tsache ndi malo ake pa mbale wayaka chithunzi 2.

Monga chinthu chomaliza, sungani dengu la batri ndi tepi yomatira pansi, ndiyeno gulitsani waya wofiira kumunda wa BAT + ndi waya wakuda ku BAT - kumunda, kuwafupikitsa mpaka kutalika kofunikira kuti asatuluke. chidule cha snowman wathu. Tsopano - kukumbukira polarity, yomwe imalembedwa pa basket basket - timayika maselo awiri a AAA (R03), otchedwa. zala zazing'ono.

Maonekedwe a snowman osonkhanitsidwa akuyimira chithunzi 3. Tikasuntha chosinthira kupita kumutu wa chidole chathu, ma LED amayatsa. Ngati chifaniziro chosonkhanitsidwa chimakonda kugwa, zidutswa zazifupi zasiliva zimatha kugulitsidwa kumalo ogulitsira pamunsi pake kuti zikhale zothandizira.

Kuti zikhale zosavuta kupachika munthu wa chipale chofewa, pali kabowo kakang'ono mu silinda yolowetsa waya kapena ulusi.

Timalimbikitsanso kanema wophunzitsira .

AVT3150 - Chipale chofewa cha LED kwa aliyense

Magawo onse ofunikira pantchitoyi akuphatikizidwa mu zida za AVT3150 zomwe zikupezeka pa: pamtengo wotsatsira Mtengo wa 15
