我正在尝试让我的指示灯每2秒钟使用一毫秒闪烁一次。由于我正在运行其他传感器,因此无法延迟。
到目前为止,我已经知道了,但是似乎没有用
#include "FastLED.h"
#define NUM_LEDS 12 // number of LEDS in neopixel ring
#define DATA_PIN 10 // for neopixel ring
CRGB leds[NUM_LEDS];
long period = 2000;
long currentMillis = 0;
long startMillis = 0;
void setup() {
FastLED.addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS);
}
void loop() {
currentMillis = millis();
if (currentMillis - startMillis >= period) {
startMillis = currentMillis;
leds[7]=CRGB(255,0,0);
FastLED.show();
}
}
这能让您更近一点吗?
#include "FastLED.h"
#define NUM_LEDS 12 // number of LEDS in neopixel ring
#define DATA_PIN 10 // for neopixel ring
CRGB leds[NUM_LEDS];
unsigned long period = 2000;
unsigned long currentMillis = 0;
unsigned long startMillis = 0;
boolean ledOn = false;
void setup() {
FastLED.addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS);
}
void loop() {
currentMillis = millis();
if (currentMillis - startMillis >= period) {
startMillis = currentMillis;
ledOn = !ledOn;
if(ledOn){
leds[7]=CRGB(255,0,0);
}
else {
leds[7]=CRGB(0,0,0);
}
FastLED.show();
}
}
