如何在Arduino中调试意外的模拟输出？

Question

我正在研究一些Neopixels和Arduino（teensy 3.2）并且两者都相当新。

我有一条LED，一个PIR和一个LDR，以区分白天和夜晚并关闭LED。我想要达到的目的是在检测到PIR运动时使LEDS达到全亮度，但仅在LDR为特定值时才会亮。

问题在于PIR超越了LDR并且无论白天或晚上都达到了全亮度，我怎样才能使LDR的模拟引脚胜过PIR？

我的代码在这里：

#include <Adafruit_NeoPixel.h>

#define PIN 5 // P0

int POTPIN =A1;    //P5
int LDRPIN = A2; //P2
int PIRPIN = 1; //P1 

 int sensorValue = 0;  //potpin sensor value
int colorValue = 0;

Adafruit_NeoPixel strip = Adafruit_NeoPixel(50, PIN, NEO_GRB + NEO_KHZ800);

void setup() {

  pinMode(PIRPIN, INPUT);  // PIR SENSOR INPUT
  strip.begin();
  strip.setBrightness(255); //overall led brightness setup (0-255)
  strip.show(); // Initialize all pixels to 'off'

}  
void loop() {

if (analogRead (LDRPIN)< 500) //    LDR light sensor, need to adjust "300"
{
  colorWipe(strip.Color(0, 0, 0), 50); // BLACK
   }


 if (digitalRead(PIRPIN) == HIGH)
  {
  analogRead (LDRPIN);
  if (analogRead (LDRPIN)> 300)
  colorWipe(strip.Color(0, 0, 0), 50); 

   else {

 colorWipe(strip.Color(255,255, 88), 50);

  delay(8000);
}

 }
}




  void colorWipe(uint32_t c, uint8_t wait) {
 for(uint16_t i=0; i<strip.numPixels(); i++) {
  strip.setPixelColor(i, c);
strip.show();
delay(wait);
 }
}


uint32_t Wheel(byte WheelPos) {
  if(WheelPos < 85) {
   return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0);
  } else if(WheelPos < 170) {
   WheelPos -= 85;
   return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);
  } else {
   WheelPos -= 170;
   return strip.Color(170,170,120); //white from potentiometer selection 
 (HALF BRIGHTNESS)
  }
}
