LEDs go off as they go up?

Hi I love this it’s great - I’m just wanting to tweak it a bit so that when the next led is illuminated the previous goes out - can you specify a rpm range somehow as the values for each led? Like ‘[4000-4999],[5000-5999],[6000]’ Thank you!

Just modify the setLedState method:

void setLedState(int rpm) {
  setGlobalState(LOW);

  // If rpm is over REV_LIMITER_RPM, all leds should be blinking at 200ms interval
  if (rpm > REV_LIMITER_RPM) {
    if (revLimiterOn) {
      setGlobalState(LOW);
    } else {
      setGlobalState(HIGH);
    }

    revLimiterOn = !revLimiterOn;
    return;
  }

  // Holds the index of the highest LED to turn on
  int maxPin = -1;

  for (int i = 0; i < PINS_COUNT; i++) {
      if (rpm >= LED_SWITCH_RPM[i]) {
          // Set the LED index
          maxPin = i;
      } else {
          // No sense in continuing the loop since the remaining RPM values are too high
          break;
      }
  }

  // Only turn on the LED we flagged above
  if (maxPin > -1) {
      digitalWrite(maxPin, HIGH);
  }
}
