Arduino 光感測

請鍵入下列程式：
#define CDS A1
#define MIC A0
#include <LiquidCrystal_I2C.h>
#define Addr 0x27
LiquidCrystal_I2C LCD(Addr,16,2);

void setup() {
     LCD.begin();
     pinMode(CDS,INPUT);
     LCD.clear();
     LCD.setCursor(0,0);LCD.print("CDS:");
     LCD.setCursor(0,1);LCD.print("MIC:");
}
void loop() {
     LCD.setCursor(4,0);LCD.print(analogRead(CDS));LCD.print(" ");
     LCD.setCursor(4,1);LCD.print(analogRead(MIC));LCD.print(" ");
     delay(200);
}
