Servo Motor with esp32 Electricalkida Pedometer electricalkida

The Servo moter is used to move the motor of any angle.This is Tower Pro SG-91 Micro Servoit is used for robotic,open toll gate,move the shaft of arm etc.It is very light. mounting hardware.

we can control the position the servo’s shaft in various angles from 0 to 180º. Servos are controlled using a pulse width modulation (PWM) signal. This means that the PWM signal sent to the motor will determine the shaft’s position.

We control the PWM capabilities of the ESP32 by sending a 50Hz signal with the appropriate pulse width.

3	SIGNAL	G4

Table 3.2.3.1: Connection of servo motor to esp32

 Programing:

#include <Servo.h>

static const int servoPin = 4;

Servo servo1;

void setup() {

    Serial.begin(115200);

    servo1.attach(servoPin);

}

void loop() {

    for(int posDegrees = 0; posDegrees <= 180; posDegrees++) {

        servo1.write(posDegrees);

        Serial.println(posDegrees);

        delay(20);

    }

    for(int posDegrees = 180; posDegrees >= 0; posDegrees--) {

        servo1.write(posDegrees);

        Serial.println(posDegrees);

        delay(20);

    }

}

We Control the Servo motor by potentimeter:

programming:

#include <Servo.h>

static const int servoPin = 4;

static const int potentiometerPin = 32;

Servo servo1;

void setup() {

    Serial.begin(115200);

    servo1.attach(servoPin);

}

void loop() {

    int servoPosition = map(analogRead(potentiometerPin), 0, 4096, 0, 180);

    servo1.write(servoPosition);

    Serial.println(servoPosition);

    delay(20);

}
