Zvitsva Zvitsva
LM555 inoshandisa simba shoma, saka inoshanda zvakanaka kumapurojekiti ebhatiri. NE555 inogona kupa yakawanda kuburitsa ikozvino, saka yakanakira mitoro mikuru senge relay uye maLED. LM555 inochengeta nguva yayo yakadzikama kunyangwe tembiricha yachinja, saka inoshanda zvakanaka munzvimbo dzakaoma. Unogona kuwana ese maICs zviri nyore, asi NE555 kazhinji inodhura zvishoma uye inoshandiswa zvakanyanya mumapurojekiti echikoro. Gara uchitarisa madheti eese maIC kuti uve nechokwadi chekuti unosarudza yakanakisa yepurojekiti yako.
lm555 vs ne555 misiyano
Paunotarisa pa lm555 uye ne555, unowana misiyano mikuru. Misiyano iyi inoshandura mashandiro anoita ic imwe neimwe mumapurojekiti ako. Kuziva zvinhu izvi kunokubatsira kusarudza iyo chaiyo timer ic kune zvaunoda. Ngatitarisei pfungwa huru.
Electrical specs
Kutanga, tarisa iwo emagetsi specs kana iwe uchienzanisa lm555 uye ne555. Ose maviri timer ic machipisi anogona kushandisa huwandu hwakasiyana hwekugovera voltage. Asi dhiraivha yavo yekubuda uye zvinodiwa zvemagetsi hazvina kufanana. Iyo ne555 inogona kusiya 200 mA kubuda ikozvino. Izvi zvinoita kuti zvive zvakanaka kune mitoro yakakura. Iyo lm555 inopa pakati pe5 mA uye 50 mA kubuda ikozvino. Saka, inopa zvishoma ikozvino, asi inoshandisa simba shoma.
Heino tafura yekukubatsira kuona kusiyana:
chikamu | Kunonyanyisa Output Current | Voltage Swing Range |
|---|---|---|
NE555 | 200 mA | 5 V kusvika 15 V |
LM555 | 5 mA yakaenzana 50 mA | Zvishoma |
Iyo lm555 inowanzoshandisa simba shoma. Izvi zviri nani kana iwe uchida kuchengetedza bhatiri kana kuchengetedza dunhu rako richitonhorera. Iyi misiyano inoratidza kuti nei uchifanira kutarisa izvo purojekiti yako inoda usati watora ic.
Kubuda uye simba
Izvo zvinobuda uye simba maficha zvakare akasiyana kune lm555 uye ne555. Iyo ne555 inopa yakasimba kubuda drive. Izvi zvakanaka pakuchinja marelay kana kuti magetsi ma LED. Iyo lm555 haina kupa yakawanda ikozvino. Asi yakagadzikana uye inoshandisa simba shoma. Kana dunhu rako richida kumhanya kwenguva yakareba pabhatiri, iyo lm555 inobatsira kuchengetedza simba.
Imwe neimwe ic ine akasiyana voltage swing. Iyo ne555 inogona kusvetuka kubva ku5 V kusvika ku15 V. Izvi zvinokupa zvimwe zvingasarudzwa zvekutakura kwakasiyana. Iyo lm555 ine diki inozungunuka. Iwe unofanirwa kutarisa kana inoenderana nedunhu rako.
Kuchengeta nguva
Kurongeka kwenguva ndiyo imwe nzvimbo iyo lm555 uye ne555 haina kufanana. Iyo lm555 ine yakakosha dhizaini shanduko inobatsira neinokonzeresa uye chikumbaridzo masaini. Semuyenzaniso, iyo lm555 inoshandisa yazvino girazi inoshanda mutoro mune yayo inokonzeresa comparator. Izvi zvinobatsira kuti ic igare yakarurama kana tembiricha yachinja. Muenzanisi wechikumbaridzo mu lm555 inoshandisawo girazi razvino uye emitter yevateveri buffer. Izvi zvinoita kuti zvishande zvirinani.
Heino tafura inoratidza dhizaini shanduko mu lm555:
Design Shanduko | tsananguro |
|---|---|
Trigger Comparator | Ikozvino girazi rinoshanda rinotsiva resistor mutoro, rinowedzera kushanda pane tembiricha. |
Threshold Comparator | Yazvino girazi rinoshanda mutoro uye emitter yevateveri buffer yakawedzerwa, inovandudza mashandiro. |
Comparator Input Priority | Shanduko dzekutanga dzekuisa dzinokanganisa kushanda kwese, kudzosera maitiro kana ichienzaniswa neNE555. |
Shanduko idzi dzinoreva kuti lm555 inopa zvirinani kuita nguva uye inogara yakagadzikana. Iwe unozoona izvi kana iwe ukashandisa iyo ic mumapurojekiti apo nguva inofanirwa kuve chaiyo, kunyangwe kuchipisa kana kutonhora. Iyo ne555 inoshanda zvakanaka kune zvakawanda zvinhu, asi iyo lm555 iri nani kana iwe uchida kushanda kwepamusoro.
Zano: Gara uchitarisa dhetadheta yeic yega yega usati wasarudza. Iwo madhizaini uye dhizaini misiyano inogona kuchinja mashandiro anoita purojekiti yako.
lm555 timer kuita
Kugadzikana kwetembiricha
Iwe unoda kuti yako 555 timer ishande munzvimbo dzinopisa uye dzinotonhora. The lm555 timer ine shanduko dzakakosha mukati. Shanduko idzi dzinoibatsira kuchengetedza nguva yakanaka kana kuchipisa kana kutonhora. Inoshandisa girazi remazuva ano mumutsara wayo uye zvikamu zvechikumbaridzo.
