Potentiometers on LED animation?

Former Member

Hi Guys, Just got my first Arduino yesterday and have jumped right into the deep end.. or atleast bouncing on the diving board over it maybe.

 

I bought the SparkFun Inventors Kit and have done up to CIRC-02. But I decided to modify it and see what I could do.

I changed the animation and added a Pot to the Circuit to adjust the delay in the program.

 

But my question is how do you program the Pot to adjust the animation instantly?

 

Right now once the animation starts it only re-adjusts the delay after it has completed the cycle.

So for example if the animation is really slow and has just started, you can adjust the Pot to speed it up but it doesn't change anything until it has completed the animation and goes to restart

 

Here is the void loop I have:

 

 

void oneAfterAnotherNoLoop(){
  sensorValue = analogRead(sensorPin);
  //the time (in milliseconds) to pause between LEDs
                      //make smaller for quicker switching and larger for slower
  digitalWrite(ledPins[0], HIGH);  //Turns on LED #0 (connected to pin 2 )
  delay(sensorValue);                //waits delayTime milliseconds
  digitalWrite(ledPins[1], HIGH);  //Turns on LED #1 (connected to pin 3 )
  delay(sensorValue);                //waits delayTime milliseconds
  digitalWrite(ledPins[2], HIGH);  //Turns on LED #2 (connected to pin 4 )

    Hello Guy Renzetti,

     

    as far as I know the way for you to go is working with interrupts. At least this would be one way to communicate and switch functions on the fly.

    Thanks, I guess I gotta keep going through the tutorials.

    I haven't gotten to interrupts yet.

     

    This is only day 3 for me now with learning programming.

    What about just removing the sensorValue = analogRead(sensorPin); variable assigning and just reading the value of the pin directly. This way you will always be using the current value of the pot at any given moment in the method instead of the stored value.

     

    Example:
    void oneAfterAnotherNoLoop(){

     

      //make smaller for quicker switching and larger for slower
      digitalWrite(ledPins[0], HIGH); //Turns on LED #0 (connected to pin 2 )
      delay(analogRead(sensorPin)); //waits delayTime milliseconds
    ...
    }

    If you look a lot of that code is just the same lines over and over and the only things you are changing are pins and whether it goes high or low. I am not sure whether this is your code or the books, but you could easily create a few for loops to clean up the code a bit. You could acheive what you want by sticking a lot of analogReads in the code, but this is cleaner i think:

     

     

    void onAfterAnotherNoLoop(){
    for( int i = 0; i<=7;i++){
       digitalWrite(ledPins[i], HIGH);
       sensorValue = analogRead(sensorPin);
       delay(sensorValue);
    }
    for( int i = 0; i<=7;i++){
       digitalWrite(ledPins[i], LOW);
       sensorValue = analogRead(sensorPin);
       delay(sensorValue);
    }
      for( int i = 8; i>=1;i--){
       digitalWrite(ledPins[i-1], HIGH);
       sensorValue = analogRead(sensorPin);
       delay(sensorValue);
    }
    for( int i = 8; i>=1;i++){
       digitalWrite(ledPins[i-1], LOW);
       sensorValue = analogRead(sensorPin);
       delay(sensorValue);
    }
    }

    void onAfterAnotherNoLoop(){

    for( int i = 0; i<=7;i++){

       digitalWrite(ledPins[i], HIGH);

       sensorValue = analogRead(sensorPin);

       delay(sensorValue);

    }

    for( int i = 0; i<=7;i++){

       digitalWrite(ledPins[i], LOW);

       sensorValue = analogRead(sensorPin);

       delay(sensorValue);

    }

      for( int i = 8; i>=1;i--){

       digitalWrite(ledPins[i-1], HIGH);

       sensorValue = analogRead(sensorPin);

       delay(sensorValue);

    }

    for( int i = 8; i>=1;i--){

       digitalWrite(ledPins[i-1], LOW);

       sensorValue = analogRead(sensorPin);

       delay(sensorValue);

    }

    }
