Micro Servo SG90 yog dab tsi?
SG90 servo yog me me servo, nrog rau qee yam compact loj loj kom muaj peev xwm koom ua ke hauv cov haujlwm uas qhov chaw tseem ceeb. Tsis tas li ntawd, nws yog kev lag luam yooj yim thiab siv tau yooj yim, nrog rau qhov xav tau ntawm lub zog tsawg heev, yog li nws kuj tseem tuaj yeem siv rau hauv embedded, IoT lossis lwm yam kev siv qis.
Raws li rau Servo SG90, lub servo lub cev muaj xws li a universal hom S connector uas yuav tuaj yeem haum rau feem ntau ntawm cov khoom lag luam. Nws yog tsim los ntawm 3 xov hlau nrog cov xim uas qhia tias txhua tus siv rau dab tsi:
- Liab: yog qhov zoo fais fab cable lossis Vcc (+)
- Brown: yog lub hwj chim cable tsis zoo (-) lossis GND (hauv av)
- Txiv kab ntxwv: nws yog lub cable uas nqa lub PPM (Pulse Position Modulation) teeb liab los tswj lub servomotor
Qee cov qauv kuj tseem muaj cov xim muaj pes tsawg leeg Dub-liab-dawb, nyob rau hauv cov ntaub ntawv twg lub tswv yim nyob rau hauv cov ntaub ntawv no yuav yog GND-Vcc-PPM teeb liab feem.
SG90 Servo nta
Nyob rau hauv cov nqe lus ntawm cov yam ntxwv kev Ntawm no servomotor, Servo SG90 sawv tawm rau:
- txhawb nqa hnyav: nruab nrab ntawm 1.2 thiab 1.6 Kg ( txaus rau nws qhov me me)
- Lub cev muaj zog torque ntawm 4.8vQhov hnyav: 1.2kg / cmXNUMX
- Kev khiav hauj lwm voltage: 4-7.2v
- Tsav ceev ntawm 4.8vNtev: 0.12s / 60º
- lub kaum sab xis tig: 120 ua
- Kev khiav hauj lwm qhov kub thiab txiasKub: -30ºC thiab +60ºC
- Qhov ntev: 22 × 11.5 × 27 hli
- Qhov hnyav: 9 g lossis 10.6 g nrog rau cable thiab connector
- Arduino-compatible: yog
- universal connector: sib xws nrog feem ntau cov xov tooj cua tswj tau txais (Futaba, JR, GWS, Cirrus, Hitec, ...)
Koj tseem yuav pom Qee qhov txawv ntawm Servo SG90, raws li:
- MG 90 S: Zoo ib yam li SG90, tab sis muaj cov khoom siv hlau thiab kev sib txuas, yog li nws tuaj yeem txhawb nqa txog 1.8kg.
- MG 996 R: Nws muaj qhov loj me me, tab sis nws tuaj yeem txhawb nqa txog 15 Kg thaum pub ntawm 6V, lossis 13 Kg yog pub ntawm 4.8v.

Qhov twg yuav servo motor qauv zoo li no ntawm tus nqi qis
Yog tias koj xav yuav Servo SG90 servomotor ntawm hom no, koj tuaj yeem pom lawv hauv qee lub khw muag khoom hluav taws xob tshwj xeeb lossis hauv Amazon platform. Piv txwv li, cov khoom pom zoo no:

Raws li koj tau pom, Lawv yog qhov pheej yig heev, thiab koj tuaj yeem yuav lawv xoob lossis hauv pob khoom rau cov neeg hlau thiab lwm cov haujlwm uas koj xav tau ntau tshaj ib qho. Tsis tas li ntawd, qee cov pob khoom suav nrog qee yam khoom siv ntxiv, xws li cov hniav, ntsia hlau, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm cov variants Raws li hais saum toj no, koj muaj cov no:
Tam sim no, yog tias koj tab tom nrhiav yog dab tsi lub servomotor muaj zog dua thiab muaj zog, muaj peev xwm muaj peev xwm tiv taus ntau dua loads thiab nrog lub zog ntau dua, ces koj kuj muaj lwm tus uas tseem compact tab sis nrog kev ua tau zoo dua:
- Quimat servo nrog hlau iav thiab txhawb nqa hnyav txog 20 Kg
- Servo Innovateking muaj peev xwm txhawb nqa txog 35 Kg ntawm kev thauj khoom ntawm nws axis

Yuav siv nws li cas nrog Arduino
Txhawm rau muab piv txwv ntawm daim duab kos rau Arduino IDE kom koj tuaj yeem pib nkag siab tias SG90 Servos ua haujlwm li cas, ntawm no yog qhov ua tau zoo. Tab sis ua ntej, cia saib seb koj yuav tsum ua li cas Txuas lub servo rau koj lub rooj tsav xwm Arduino:
- VDC: Nws yuav tsum tau txuas nrog lub zog hluav taws xob sab nraud lossis rau 5V txuas ntawm Arduino. Yog tias koj yuav siv ntau lub hwj chim, nco ntsoov muab tso rau hauv av lossis GND ib txwm kom tsis txhob muaj teeb meem.
- GND: Koj tuaj yeem txuas nws mus rau GND ntawm Arduino board.
- PPM teeb liab: tuaj yeem mus rau ib qho ntawm PWM pins ntawm Arduino. Piv txwv li, rau D11 hauv peb cov duab kos.
Kom pom piv txwv qhov chaws, uas koj tuaj yeem sim thiab hloov kho raws li koj xav tau, koj muaj ob qho tib si koj tus kheej cov qauv uas koj tuaj yeem pom hauv IDE nrog lub tsev qiv ntawv Servo.h, zoo li qhov no lwm tus:
#include <Servo.h>
Servo myservo; //Crear el objeto servo
int pos = 0; //Posición inicial del servo SG90
void setup() {
myservo.attach(11); //Vincular el pin 11 de Arduino al control del Servo SG90
}
void loop() {
//Cambia la posición de 0º a 180º, en intervalos de 25ms
for (pos = 0; pos <= 180; pos += 1)
{
myservo.write(pos);
delay(25);
}
//Vuelve desde 180º a 0º, con esperas de 25ms
for (pos = 180; pos >= 0; pos -= 1)
{
myservo.write(pos);
delay(25);
}
}
