Chapter 6: Activity 6.5 Modify to have this as your setup()

void setup() {

for(int i=0; i< CircuitPlayground.strip.numPixels(); i++) {
CircuitPlayground.setPixelColor(i, ( 0, 0, 255));
CircuitPlayground.strip.show();
CircuitPlayground.playTone(984, 30);
delay(40);
}
delay(1000);
CircuitPlayground.clearPixels();
