Movimento de servo motores utilizando o arduino

O controle do ângulo de cada um é feito através de um potênciometro que na sua faixa de valores de resistência/tensão no pino de entrada, é convertido a um ângulo de 0 a 180 Graus. Aqui está o circuito e a programação utilizada. A montagem e a simulação foi feita no site: www.tinkercad.com, gratuíto. 

Programação proposta:

#include <Servo.h>

Servo myservo1;  // create servo object to control a servo

Servo myservo2;  // create servo object to control a servo

Servo myservo3;  // create servo object to control a servo

Servo myservo4;  // create servo object to control a servo

int potpin1 = 0;  // analog pin used to connect the potentiometer

int val1;    // variable to read the value from the analog pin

int potpin2 = 1;  // analog pin used to connect the potentiometer

int val2;    // variable to read the value from the analog pin

int potpin3 = 2;  // analog pin used to connect the potentiometer

int val3;    // variable to read the value from the analog pin

int potpin4 = 3;  // analog pin used to connect the potentiometer

int val4;    // variable to read the value from the analog pin

void setup() {

  myservo1.attach(3);  // attaches the servo on pin 9 to the servo object

  myservo2.attach(4);  // attaches the servo on pin 9 to the servo object

  myservo3.attach(5);  // attaches the servo on pin 9 to the servo object

  myservo4.attach(6);  // attaches the servo on pin 9 to the servo object

  

  pinMode(8, INPUT);

  pinMode(potpin1, INPUT);

  pinMode(potpin2, INPUT);

  pinMode(potpin3, INPUT);

  pinMode(potpin4, INPUT);

}

void loop() {

  

  int botao = digitalRead(8);

  

  if(botao==1)

  {

  val1 = analogRead(potpin1);            // reads the value of the potentiometer (value between 0 and 1023)

  val1 = map(val1, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)

  myservo1.write(val1);                  // sets the servo position according to the scaled value

  

  

  val2 = analogRead(potpin2);            // reads the value of the potentiometer (value between 0 and 1023)

  val2 = map(val2, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)

  myservo2.write(val2);                  // sets the servo position according to the scaled value

  

  val3 = analogRead(potpin3);            // reads the value of the potentiometer (value between 0 and 1023)

  val3 = map(val3, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)

  myservo3.write(val3);                  // sets the servo position according to the scaled value

  

  val4 = analogRead(potpin4);            // reads the value of the potentiometer (value between 0 and 1023)

  val4 = map(val4, 0, 1023, 89, 180);     // scale it to use it with the servo (value between 0 and 90)

  myservo4.write(val4);                  // sets the servo position according to the scaled value

  

 

  delay(15);                           // waits for the servo to get there

  }
