  • I want my statement to run in a continuous loop until I activate my momentary button switch.
    I have a switch that changes lighting modes but stops after the statement is finished.

    //Theatre-style crawling lights.
    void theaterChase(uint32_t c, uint8_t wait) {
      for (int j=0; j<10; j++) {  //do 10 cycles of chasing
        for (int q=0; q < 3; q++) {
          for (int i=0; i < strip.numPixels(); i=i+3) {
            strip.setPixelColor(i+q, c);    //turn every third pixel on
          }
          strip.show();

          delay(wait);

          for (int i=0; i < strip.numPixels(); i=i+3) {
            strip.setPixelColor(i+q, 0);        //turn every third pixel off
          }
        }
      }
    }

    So instead of the j<10; I am not sure what to change to get my constant loop. Is there an infinite symbol that I can use in my for statement?

    (If you need the rest of the code, I can post it. I wanted to try and not bog down your thread.)

  • I will be adding/hacking some additional modes into this, but I am confident that when I get this sorted, I will have it under control. The additiona code is proven, in other projects. This code is also proven but stops when the statement is run and I want  continuous lighting.
