Potentiometer not working smooth

Using Arduino Programming Questions

hi i have 3 slide potentiometer, when i move them up and down they are working fine, but if i move them little and then little more and little more, the potentiometer they don't respond from the first small move, they start to respond after lets say i move them 2cm in range. because i use those potentiometer like faders, i need them to be more sensitive. something i am missing in the code. i change timeout or vartherhold but is not what i was expecting.

int pot[NPOT] =  { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };
int ppotv[NPOT] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, };
int potCState[NPOT] = {0};
int potPState[NPOT] = {0};
int potVar = 0;
int lastCcValue[NPOT] = {0};
int TIMEOUT = 50;
byte varThreshold = 8;
boolean potMoving = true;
unsigned long pTime[NPOT] = {0};
unsigned long timer[NPOT] = {0};

void readPots () {



  for (int i = 0; i < NPOT; i++) { 
    potCState[i] = muxpots.read(pot[i]);
  }

  for (int i = 0; i < NPOT ; i++) {

    potVar = abs(potCState[i] - potPState[i]); 

    if (potVar >= varThreshold) {  //sets a threshold for the variance in the pot state, if it varies more than x it sends the cc message
      pTime[i] = millis(); 
    }
    timer[i] = millis() - pTime[i]; 
    if (timer[i] < TIMEOUT) { 
      potMoving = true;
    }
    else {
      potMoving = false;
    }

    if (potMoving == true) { 
      int ccValue = map(potCState[i], 0, 1023, 0, 127);
      if (lastCcValue[i] != ccValue) {
        
        MIDI.sendControlChange(100 + i, map(potCState[i], 0, 1023, 0, 127), 1); 
        
        potPState[i] = potCState[i]; 
        lastCcValue[i] = ccValue;
      }
    }
  }

@tasoscy, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the Installation & Troubleshooting category.

Please post your full code (or a representative example that shows the problem and makes use of the readPots() function).

please post the definition for this function

why is this needed?
