Oh DEAR.

This is an excellent example of the reason for my feelings towards Fritzy.

How to make a schematic you can post.

When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…

1: try disconnecting EVERYTHING else.
2: draw a schematic of how JUST the two pots are connected to the arduino.
3: Run this code, that does a dummy read after EACH change of input

void loop() {
  int RT = analogRead(A6);
  RT = analogRead(A6);
int LT = analogRead(A8);
  LT = analogRead(A8);
  Serial.print("RT:");
  Serial.print(RT);
  Serial.print(",");
  Serial.print("LT:");
  Serial.println(LT);
}
