VGA pong issue with 2 pots

Projects General Guidance
1

so im following this tutorial, and the topic is locked so i cant ask there

great work by him, and everything works up until i plug a second pot in.

code is the v1.3, and as soon as i plug in the second pot whenever i turn either, both paddles just start spasming out. I tried just reading 2 analog values individually to test and i noticed that the value is affected by the other one.

how can i solve this issue?

Please share your experimental sketch. And a link to or post a schematic.

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A1);
    int sensorValue1 = analogRead(A5);
  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  float voltage = sensorValue * (5.0 / 1023.0);
  float voltage1 = sensorValue1 * (5.0 / 1023.0);
  // print out the value you read:
  Serial.println(voltage);
  Serial.println(voltage1);
  delay (1000);
}

after reviewing and adding identifiers to the voltage, it all seems to work fine now, at least in this sketch. the game of pong is still broken.
