七彩雷电云
大大们求救啊，我想做一盏雷电云，人不来的时候是7彩的，有人靠近了就打雷闪电。这是7彩灯带的代码（灯带是炫彩 WS2812 LED灯带 3米）：
#include <Adafruit_NeoPixel.h>
#define PIN 6
#define LED_COUNT 60
Adafruit_NeoPixel leds = Adafruit_NeoPixel(LED_COUNT, PIN, NEO_GRB + NEO_KHZ800);
void setup() {
leds.begin();
clearLEDs();
leds.show();
}
void loop() {
for (int i=0; i<LED_COUNT; i++)
{
rainbow(i);
delay(50);
}
}
void clearLEDs()
{
for (int i=0; i<LED_COUNT; i++)
{
leds.setPixelColor(i, 0);
}
}
void rainbow(byte startPosition)
{
int rainbowScale = 192 / LED_COUNT;
for (int i=0; i<LED_COUNT; i++)
{
leds.setPixelColor(i, rainbowOrder((rainbowScale * (i + startPosition)) % 192));
}
leds.show();
}
uint32_t rainbowOrder(byte position)
{
if (position < 31)
{
return leds.Color(0xFF, position * 8, 0);
}
else if (position < 63)
{
position -= 31;
return leds.Color(0xFF - position * 8, 0xFF, 0);
}
else if (position < 95)
{
