Zvichida kuti muzvirongwa zvako iwe unofanirwa kugadzirisa iyo voltage kana voltage yedunhu. Semuenzaniso, kana iwe uine 12v kuburitsa uye iwe unofanirwa kusimbisa iyo 6v dunhu, iwe ungangoda chimwe chinhu chinogona kuvashandura. Icho chinhu ndicho voltage mugoveri. Dunhu rakareruka rinoita zvakafanana nekuti shanduko yaizoita sei, kunyangwe ichivimba nemitemo yakasiyana kwazvo yekushanda kwayo.

Naizvozvo, haufanire kuvhiringidza pakati peshanduko nemagetsi akaparadzanisaSezvo imwe ichishandisa mamhepo uye induction kushandura imwe voltage kuita imwe, uye imwe yacho iri nyore dunhu rakagadzirwa nema resistor ayo anokwanisa kukamura magetsi kuita maviri madiki ma voltages. Semuenzaniso, mududziri anogona kushandura gumi nemaviri pakuisa kwayo kuita 12v pane zvayakaburitsa, asi izvo zvinoitwa nemugovanisi kushandura iwo gumi nemaviri kubva pakuisa kwayo kuita maviri mavhoriyamu pane ayo anoburitsa. Iwe unoona mutsauko?

## Chii chinonzi voltage divider?

Un voltage kana voltage mugoveri Iyo idunhu iyo, sekuratidzwa kwezita rayo, inokamura mhepo iriko pane yayo yekuisa mune mamwe madiki ma voltages pakuburitsa kwayo. Naizvozvo, chidimbu chakakosha kumatunhu emagetsi anoda ma voltages akadzika pane aya anopihwa nemagetsi, mabhatiri, kana socket yauinayo.

Ndisati ndapa muenzaniso weiyo gumi nemaviri iyo ini yandakakamura kuita maviri matanhatu mavhoriyamu, asi iwo anoparadzanisa magetsi haagari achitangira ipapo hafu yemagetsi ekuisa. Semuenzaniso, zvinogona kunge zviri izvo kuti iwe une 9v bhatiri uye iwe unofanirwa kukamura iyo voltage mu6 ne3v, iyo zvaizoitawo zvakarendiko kuti, havafanirwe kunge vakaenzana ...

### Nheyo pazviri zvakavakirwa

Sezvinoonekwa mumufananidzo, dunhu rekutanga rakareruka. Iwe unongoda bhatiri kana sosi iyo inogona kunge yakabatana pasi uye neVin mumufananidzo kupa simba mugoveri. Iyo yekuparadzanisa magetsi pachayo yaizongogadzirwa chete nemaviri anopikisa akabatana mune akateedzana. Nekudaro, uchishandisa fomula yaunoona mumufananidzo, simba rinobuda iro ringavepo pakati pevhu neVout chingave mugumisiro wekukamura kukosha kwekupikisa 2 pakati pehuwandu hweR1 neR2, uyezve nekuwedzera mhedzisiro nemhepo yekupinda.

Iko kune capacitive voltage divider zvakare, kunyangwe ivo vari vashoma vanozivikanwa pane avo vanopokana ...

kubudikidza ejemploFungidzira kuti iwe une yekuisa voltage ye20v, iine R1 = 1k uye R2 = 2k. Izvi zvinokonzeresa kuburitswa kwemhepo yedu yekuparadzanisa kuve 13v. Ehezve iwe unogona kutamba nehunhu hweanopokana kuti ugadzire iyo divi yemagetsi iwe yaunoda. Mumwe muenzaniso, kana iwe ukangosiyana chete R2 kuitira kuti ingori 0,5k saka ichave iri 6,6v kuburitsa. Nyore here?

## Iko kune magetsi ekuwedzera?

Hongu pane magetsi anowedzera. Mune ino kesi zvakare iri nyore dunhu inosanganisa diode mune yakafanana. Izvo zvinopa zvinopesana, kuwedzera simba rekuisa nezvinhu zvakasiyana kuti uwane kukwirisa kwakakwira. Muchokwadi, iwo musimboti unoshandiswa mune akakurumbira mainverter emalaptop, ayo anopisa zvakanyanya, achisiya nzvimbo inopisa shure kwescreen ...

Avo ma inverters hapana chimwe chinhu kunze kwedunhu rine ma diode mune yakafanana kuwedzera simba rinopihwa nebhatiri reLaptop kumeta mamwe marudzi emapaneru ekuratidzira. Muchikamu chega chega, inowana magetsi kudzamara yasvika pamatanho akakwirira ari kutsvakwa, unogona kuita bhatiri remamota mashoma kuwana mazana kana zviuru zvevolts.

### Mamwe akapatsanura / akawanda

Zviri pachena zvemagetsi zvinofambira mberi zvakanyanya uye inobvumidza kusanganisa iyi mhando yemaseketi mune imwechete chip. Uye zvakare, kune vazhinji vanogadzira pamusika vanoshandisa mamwe marudzi evapatsanuri uye kuwanda mudunhu rimwe chete. Ivo vapatsanuri uye kuwanda kwandirikureva pano ndidzo nguva dzewachi. Asi iwe unofanirwa kuziva kuti kune zvekare masimba ekuwedzera uye anopatsanura, nezvimwe.

## Nzira yekuwana sei divi remagetsi

Hezvino iwe une nzira mbiri dzekuwana muganho wemagetsi. Kune rimwe divi iwe unogona kuzvivakira wega wedunhu redunhu, nekuti hazvidi zvinhu zvinodhura uye zvakachipa. Asi kune rimwe divi, kune zvekare mamwe magetsi anopa izvo zvakabuda zvinoverengeka zvakasiyana zvemagetsi uye zvakagadzirira kushandiswa ...

Iyo inyaya yekutamba nema resistor uye kuverenga iyo voltage iwe yaunoda yako projekiti. Iwe unogona kuona rumwe ruzivo muchikamu umo panotsanangurwa misimboti yechinyorwa chino. Nenzira, sechirevo, Ini ndinokurudzira kuti ushandise potentiometer senge R1, saka uchave nekushomeka kwekushomeka kuti uwane dzakasiyana voltages pane zvinobuda pasina kugadzirisa dunhu.

Kune rumwe rutivi, iwe unogona zvakare kuwana mutsara pakati peVout neVin yekubatanidza poindi neR1. Saka iwe unenge uine ma voltages maviri akasiyana atakataura pakutanga, pamwe neizvo zvinopa zviteshi pakati pese zviri zviviri resistors neGND ...

Kukanganisa kwakajairika, kana iwe uri kushandisa iyo voltage divider kuburitsa, kana iwe uchitova nechinhu chakabatanidzwa, chinodya uye chine simba pane iyo voltage. Nechikonzero ichi, kana iwe ukaisa chimwe chinhu chakaenzana neicho chakange chatobatanidzwa, iwo magetsi anopihwa anogona kudonha uye haizove akafanana neakaverenga. Saka ndezve kungobatanidza chinhu chimwe chete.

### Tenga magetsi

La sarudzo iri nyore ndeyekutenga kwakananga magetsi anove akatogadzirwa nezvakasiyana magetsi kubuda, uye izvo zvinowanzo sanganisira zvimwe zvekuwedzera. Kune iwo emitengo yakachipa kana mamwe aine mamwe mabasa chimwe chinhu chinodhura….

Chokwadi unogona isa gadziriro yemagetsi pabhobhodhi uye uibatanidze nemapurojekiti ako eArduino nyore. Uye hazvishande chete kupatsanura voltages sezvataona, iwe unogona kupatsanura izvi zvakapatsanura nekupinza zvimwe zvinhu zvakaita sema pushbuttons kana switch kuitira kuti nemagetsi akafanana iwe ugone kudzora akati wandei michina pane zvinobuda. Semuenzaniso, chidimbu chiri nyore chakabatana nebhodhi Arduino UNO Kuti uverenge kukosha kubva munhevedzano

El kodhi yeArduino IDE Chingave chinhu chakadai.
