arduino平衡传感器控制灯带展现多种不同的灯光效果的代码

以下是一个基于Arduino的平衡传感器控制灯带展现多种不同灯光效果的代码：

#include <FastLED.h>

#define DATA_PIN 6
#define LED_TYPE WS2811
#define COLOR_ORDER GRB
#define NUM_LEDS 60

CRGB leds[NUM_LEDS];

#define SAMPLE_INTERVAL 20 // 20ms sample interval
#define FILTER_FACTOR 0.1 // 10% filtering

const int xPin = A0;
const int yPin = A1;
const int zPin = A2;

float xAcc, yAcc, zAcc;
float xAccFiltered, yAccFiltered, zAccFiltered;

void setup() {
  Serial.begin(115200);
  FastLED.addLeds<LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS);
}

void loop() {
  // Read accelerometer
  xAcc = analogRead(xPin);
  yAcc = analogRead(yPin);
  zAcc = analogRead(zPin);

  // Low-pass filter
  xAccFiltered = (xAcc * FILTER_FACTOR) + (xAccFiltered * (1 - FILTER_FACTOR));
  yAccFiltered = (yAcc * FILTER_FACTOR) + (yAccFiltered * (1 - FILTER_FACTOR));
  zAccFiltered = (zAcc * FILTER_FACTOR) + (zAccFiltered * (1 - FILTER_FACTOR));

  // Convert to tilt angle
  float xTilt = (xAccFiltered - 512) / 1024.0 * 90.0;
  float yTilt = (yAccFiltered - 512) / 1024.0 * 90.0;
  float zTilt = (zAccFiltered - 512) / 1024.0 * 90.0;

  // Map tilt angle to LED index
  int xIndex = map(xTilt, -90, 90, 0, NUM_LEDS - 1);
  int yIndex = map(yTilt, -90, 90, 0, NUM_LEDS - 1);
  int zIndex = map(zTilt, -90, 90, 0, NUM_LEDS - 1);

  // Update LED colors
  for (int i = 0; i < NUM_LEDS; i++) {
    if (i == xIndex) {
      leds[i] = CRGB::Red;
    } else if (i == yIndex) {
      leds[i] = CRGB::Green;
    } else if (i == zIndex) {
      leds[i] = CRGB::Blue;
    } else {
      leds[i] = CRGB::Black;
    }
  }

  // Show LED colors
  FastLED.show();

  // Wait for next sample
  delay(SAMPLE_INTERVAL);
}

该代码使用了一个低通滤波器来平滑传感器的读数，并使用`map()`函数将倾斜角度映射到LED索引。然后，根据每个轴的倾斜，将相应的LED设置为红色、绿色或蓝色。最后，使用FastLED库将颜色渲染到LED带上。您可以根据需要修改代码以实现不同的灯光效果。
