Reading Multiple Voltages Through Serial [Arduino]

I am attempting to create a motorized rotary potentiometer connected to max/MSP for recall of parameters. I have gotten one potentiometer to work, but when I try it with two one of the pots controls the other. Max is not reading the information for both Voltages separately. Attached are my patches and circuit.
The Alps pot pins are labeled, left to right: Dummy|A-read|GND|5v|A-read|GND|5v|Dummy

Here is a video of one pot

This is the code for ONE potentiometer:

    const int servoPos=7;
    const int servoNeg=8;
     
    float potVolt = A1;
     
    void setup(){
      Serial.begin(9600);
      pinMode(servoPos, OUTPUT);
      pinMode(servoNeg, OUTPUT);
    }
     
    void loop(){
      byte positive;
      float potVolt = analogRead(A1)/ 4;
     
        if (Serial.available()) {
         positive = Serial.read();
                    //threshold of +/- 1.5 so pot doesn't bounce around
          if (potVolt > (positive + 1.5)) {
          digitalWrite(servoPos, LOW);
          digitalWrite(servoNeg, HIGH);
        }
        else if (potVolt < (positive - 1.5)) {
          digitalWrite(servoPos, HIGH);
          digitalWrite(servoNeg, LOW);
        }
              if (potVolt == positive) {
          digitalWrite(servoNeg, LOW);
          digitalWrite(servoPos, LOW);
        }    
        }
     
      Serial.print(positive);
      Serial.print(" ");
      Serial.println(potVolt);  
     
    }

and this is the code I attempted for two. You can view the voltages in the IDE Serial Monitor, but in Max/MSP it is sending them both to one integer object and interpolating the voltages.

const int servoPos1=2;
const int servoNeg1=3;
const int servoPos2=7;
const int servoNeg2=8;
byte pot1,pot2;

float potVolt1 = A5;
float potVolt2 = A1;

void setup(){
  Serial.begin(9600);
  pinMode(servoPos1, OUTPUT);
  pinMode(servoNeg1, OUTPUT);
  pinMode(servoPos2, OUTPUT);
  pinMode(servoNeg2, OUTPUT);
}

void loop(){

  float potVolt1 = analogRead(A1)/ 4;
  float potVolt2 = analogRead(A5)/ 4;
  
    while (Serial.available()) {
     pot1 = Serial.read();
     pot2 = Serial.read();
     
      if (pot1 > (potVolt1 + 1.5)) {
      digitalWrite(servoPos1, LOW);
      digitalWrite(servoNeg1, HIGH);
    }
    else if (pot1 < (potVolt1 - 1.5)) {
      digitalWrite(servoPos1, HIGH);
      digitalWrite(servoNeg1, LOW);
    }
          if (pot1 == potVolt1) {
      digitalWrite(servoNeg1, LOW);
      digitalWrite(servoPos1, LOW);
    }    
    
    
          if (pot2 > (potVolt2 + 1.5)) {
      digitalWrite(servoPos2, LOW);
      digitalWrite(servoNeg2, HIGH);
    }
    else if (pot2 < (potVolt2 - 1.5)) {
      digitalWrite(servoPos2, HIGH);
      digitalWrite(servoNeg2, LOW);
    }
          if (pot2 == potVolt2) {
      digitalWrite(servoNeg2, LOW);
      digitalWrite(servoPos2, LOW);
    }    
    
    }
  
  Serial.print(pot1);
  Serial.print(" ");
  Serial.println(potVolt1);  

  Serial.print(pot2);
  Serial.print(" ");
  Serial.println(potVolt2);  

}
  

*also note that in my diagram, 123dcircuit doesn't have a pot and motor joined, so I had to use them as separate pieces in the image, but they are ONE UNIT in real life.*Arduino-Breadboard connections
