【问题描述】:
所以我需要一些帮助来查看和编辑下面的代码。有没有办法让它比我做的更有效?另外,有没有更好的方法来做我做过的一些方法?非常感谢答案(我对 Arduino 还很陌生)。
下面的代码是一个走廊灯带,当 Arduino 上的距离传感器检测到附近某个距离以下的任何物体时,它会亮起(是的,我想过使用运动传感器,但我手头只有距离传感器)。
const int trigPin = 9;
const int echoPin = 10;
float duration, distance;
#include <FastLED.h>
#define LED_PIN 6
#define NUM_LEDS 60
int timingnum = 0;
//#define BRIGHTNESS bright
int bright = 100;///the brightness of the leds
int lednum = 60;///the number of leds available
int timer;
CRGB leds[NUM_LEDS];
void setup() {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS);
// FastLED.setBrightness( BRIGHTNESS );
}
void loop() {
lights();
}
void sensor() { ///THIS IS CLEAN
digitalWrite(trigPin, LOW);
delayMicroseconds(timingnum);
digitalWrite(trigPin, HIGH);
delayMicroseconds(timingnum);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration*.0343)/2;
Serial.print("Distance: ");
Serial.println(distance);
}
// in the lights the reason why it wouldnt output the data for the
// represented while loops is because the while loop continued running
// without the data from the distance and thus it needs to constantly
// be updated in the while loop conditional statments
void lights() {
sensor(); //data update
while (distance <= 10) {
for (int x = 0; x <= 60; x++) {
leds[x] = CRGB(255,255,255);
FastLED.show();
sensor(); //sensor update
}
for (timer = 0; timer <=800; timer++) {
sensor();
}
sensor(); //replaces the data updates above
}
sensor(); //sensor update
while (distance >= 11) {
for (int x = 0; x <= 60; x++) {
leds[x] = CRGB(0,0,0);
FastLED.show();
}
sensor(); //data update
}
}
