Isku xirka fiilada bandhiga LED

Guuldarrooyinka badan ee soo-bandhigidda LED-ka midabka buuxa waxaa sababa rakibid aan habboonayn.Sidaa darteed, tallaabooyinka waa in si adag loo raaco inta lagu jiro habka rakibidda, gaar ahaan inta lagu jiro rakibidda ugu horreysa.Si loo yareeyo dhacdooyinka khaladaadka, aan eegno LED-ka midabka buuxa.Jaantuska fiilooyinka ee shaashadda bandhigga iyo habka fiilooyinka ee tillaabooyinka loogu talagalay rakibidda muraayad LED ah oo midabkiisu dhan yahay.

1. Jaantuska xidhiidhka fiilada ee LED-ka midabka buuxa

Labo, tillaabooyinka habka

1. Hubi in danabka sahayda korantada ee muraayadda midabka buuxda ee LED ay tahay mid caadi ah.

Soo hel sahayda wareejinta oo leh xiriiro togan iyo mid taban oo DC ah, ku xidh xadhigga korantada ee 220V ilaa sahayda wareejinta, (hubi inay si sax ah ugu xidhan tahay, ku xidh AC ama terminalka NL), oo ku xidh qalabka korontada.Ka dib isticmaal multimeter iyo qaabka DC si aad u cabbirto korantada si aad u hubiso in danabku u dhexeeyo 4.8V-5.1V, oo uu jiro buro agtiisa ah, kaas oo lagu hagaajin karo Philips screwdriver, qaabka DC ayaa loo isticmaalaa in lagu cabbiro danab.Si loo yareeyo kulaylka shaashadda oo cimrigeeda loo dheereeyo, korantada waxaa lagu hagaajin karaa 4.5V-4.8 halkaasoo shuruudaha dhalaalku aanu sarreyn.Ka dib markii la xaqiijiyo in aysan jirin wax dhib ah oo ku saabsan danab, gooyay korontada oo sii wad inaad ururiso qaybaha kale.

2. Demi awoodda muraayadda midabka buuxa ee sawirka.

Ku xidh V+ siligga cas, V+ silig madow, siday u kala horreeyaan ku xidh kaadhka kantaroolka LED-ka ee midabka buuxa iyo guddida LED-ka, iyo siliga madow ee kaadhka xakamaynta iyo korontada GND.Casaanku waxa uu isku xidhaa kaadhka xakamaynta +5V danab iyo boodhka cutubka VCC.Loox kastaa wuxuu leeyahay silig.Marka aad dhammayso, hubi in xidhiidhku sax yahay.

3. Ku xidh kantaroolaha muraayada midabka leh ee midabka buuxa iyo sabuuradda cutubka.

Isticmaal fiilooyinka iyo isku xirka wanaagsan.Fadlan fiiro gaar ah u yeelo jihada oo ha celin xiriirka.Boodhka soo-bandhigidda ee midabka buuxa leh wuxuu leeyahay laba is-dhexgal oo 16PIN ah, 1 waa wax-soo-saar, 1 waa soo-saar, agagaarka 74HC245/244-na waa la gelin, kaarka kantaroolkuna wuxuu ku xiran yahay gelinta.Wax soo saarku wuxuu ku xiran yahay gelinta guddiga cutubka xiga.

4. Ku xidh khadka xogta RS232 ee muraayadda midabka buuxa ee LED.

Ku xidh hal daraf oo fiilada xogta la sameeyay oo ku xidhi dekedda DB9 ee kombayuutarka, iyo dhammaadka kale kaadhka kantaroolka muraayadda ee midabka buuxa, ku xidh 5 pin (brown) ee DB9 GND ee kaadhka xakamaynta, oo ku xidh 3 pin (brown) ee DB9 kontoroolka RS232-RX ee kaadhka.Haddii kombayutarkaagu aanu lahayn deked taxan, waxaad ka iibsan kartaa USB ilaa RS232 fiilada beddelka dekedaha ee Dukaanka Kombiyuutarka.

5. Hubi xidhiidhka muraayada midabka buuxa mar labaad.

Haddii siliga madow uu si sax ah ugu xidhan yahay -V iyo GND, iyo siliga cas uu ku xidhan yahay +V iyo VCC+5V.

6. Daar korontada 220V oo fur software-ka ay soo dejisay muraayadda LED-ka ee midabka buuxa.

Sida caadiga ah, nalka korantadu waa shidan yahay, kaarka kantaroolku waa shidan yahay, midabka LED-ka oo buuxa ayaa muujinaya.Haddii wax aan caadi ahayn, fadlan hubi xidhiidhka.Ama hubi cilad-raadinta.Deji xuduudaha shaashadda oo dir qoraal-hoosaadyo.Fadlan tixraac tilmaamaha software.
