Controlling Two Servos with One Joystick & Keeping Servos In End Position

Using Arduino Programming Questions

I'm trying to control two servos using one joystick. I need each servo to remain in its end orientation after the joystick is released instead of returning to center. This is my current code. Thank you.

#include <Servo.h>


int servoPin1 = 6; 
int servoPin2 = 7;  // servo signal connection


Servo myServo1;
Servo myServo2;
int servoPos1 = 90;
int servoPos2 = 90;
int servoMax = 165;
int servoMin = 15;
int servoMove = 3;  // number of degrees per movement


int joyPin1 = A0;
int joyPin2 = A1; 
int joyValue1 = 0;
int joyValue2 = 0;
int joyCenter = 350; // neutral value of joystick
int joyDeadRange = 150; // movements by this much either side of center are ignored


unsigned long curMillis;
unsigned long readIntervalMillis = 100;
unsigned long lastReadMillis;

void setup() {
  Serial.begin(9600);
  
  myServo1.attach(servoPin1);
  myServo1.write(servoPos1);
  myServo2.attach(servoPin2);
  myServo2.write(servoPos2);
}

void loop() {{
  curMillis = millis();
  readJoystick();
  moveServo();
  showPosition();
}}

void readJoystick() {
      // check the time
  if (curMillis - lastReadMillis >= readIntervalMillis) {
    lastReadMillis += readIntervalMillis;
      // read the joystick
    joyValue1 = analogRead(joyPin1);
      // figure if a move is required
    if (joyValue1 > joyCenter + joyDeadRange) {
      servoPos1 += servoMove;
    }
    if (joyValue1 < joyCenter - joyDeadRange) {
      servoPos1 -= servoMove;
    }
      // check that the values are within limits
    if (servoPos1 > servoMax) {
      servoPos1 = servoMax;
    }
    if (servoPos1 < servoMin) {
      servoPos1 = servoMin;
    }
}

    joyValue2 = analogRead(joyPin2);
      // figure if a move is required
    if (joyValue2 > joyCenter + joyDeadRange) {
      servoPos1 += servoMove;
    }
    if (joyValue2 < joyCenter - joyDeadRange) {
      servoPos1 -= servoMove;
    }
      // check that the values are within limits
    if (servoPos2 > servoMax) {
      servoPos2 = servoMax;
    }
    if (servoPos2 < servoMin) {
      servoPos2 = servoMin;
    }
}

void moveServo() {
  myServo1.write(servoPos1);
  myServo2.write(servoPos2);
}

void showPosition() {
  Serial.print("JoyValue1 ");
  Serial.print(joyValue1);
  Serial.print("   ServoPos1 ");
  Serial.println(servoPos1);
  Serial.print("JoyValue2 ");
  Serial.print(joyValue2);
  Serial.print("   ServoPos2 ");
  Serial.println(servoPos2);
}

Likely you need to read a button press to indicate when the hold position is reached and to ignore further joystick readings. Press the same button again to tell it to move to a new position.
