Arduino

int photocellPin = 0; // 光敏電阻 (photocell) 接在 anallog pin 2
int photocellVal = 13; // photocell variable
int a=0;
void setup() {
  Serial.begin(9600);
  pinMode(photocellVal, OUTPUT);
}
byte data[1];
void loop() {
  // 讀取光敏電阻並輸出到 Serial Port
  photocellVal = analogRead(A0);
  //Serial.println(photocellVal);
  delay(200);   
  data[0]=photocellVal;
  Serial.write(data,1);
}
