I am working on a project using a Rotary Encoder and I am trying to recieve the output from the encoder. As it stands I am able to get a count for degrees of change and direction of rotation, however depending on the speed the encoder spins I get a varying rotational output. For example if I rotate it slowly I can get 100's of counts for 180 degrees of rotation, but if I do so fast, then I could get 10 or so counts.

void loop() {
  if(counter <= 1000){
    counter++;
    Serial.println(counter);
  }
}

The code for the Rotary Encoder: Dt and Clk pin representing the 2 signal wires, both being pulled up

void loop(){

  //take clk pin state
  clkState = digitalRead(clkPin);

  //if clk state changed then wheel is rotating, react to rising edge to avoid double count
  if(clkState != preClkState && clkState == HIGH){
    Serial.write(digitalRead(dtPin));
    //check direction of spin based on dtpin
    if(digitalRead(dtPin)== HIGH){
      counter++;

      clockwiseDirection = true;
    }else{
      counter--;

      clockwiseDirection = false;
    }

    //output values
    Serial.write("Direction: ");
    if(clockwiseDirection){
      Serial.write("Clockwise | Counter: ");
    }else{
      Serial.write("Counter Clockwise | Counter: ");
    }

    Serial.print((int)counter);
    Serial.print("\n");

  }

  //update pre pos
  preClkState = clkState;

}

Thanks in advance.
