Arduino 和 LED Display

hinghui88

我本身刚刚认识了Arduino这东西，是从一位来公司做实习的外国实习生。
但是Project还没完成他因为私人的事离开了马来西亚。
现在，我只剩下一个Arduino和LED Display。我请教了很多人，但是他们都没办法回答我的问题，希望这边的大神现身解答。

我有一个Arduino和他的Code。

const int SonarPin1 = A0;
const int SonarPin2 = A2;
const int SonarPin3 = A4;
const int SonarPin4 = A6;
const int SonarPin5 = A8;
const int SonarPin6 = A9;
const int SonarPin7 = A11;
const int SonarPin8 = A13;

#define txPin 14
#define rxPin 15

void setup() {
  // initialize serial communication:
  Serial.begin(9600);
}

void loop()
{
  long duration, duration1, duration2, duration3, duration4, duration5, duration6, duration7, duration8;
  long parking = 8;

  // first sensor
  duration1 = analogRead(SonarPin1)/2;

  duration2 = analogRead(SonarPin2)/2;

  duration3 = analogRead(SonarPin3)/2;

  duration4 = analogRead(SonarPin4)/2;

  duration5 = analogRead(SonarPin5)/2;

  duration6 = analogRead(SonarPin6)/2;

  duration7 = analogRead(SonarPin7)/2;

  duration8 = analogRead(SonarPin8)/2;


  if(duration1 < 8)
    parking--;

  if(duration2 < 8)
    parking--;

  if(duration3 < 8)
    parking--;

  if(duration4 < 8)
    parking--;

  if(duration5 < 8)
    parking--;

  if(duration6 < 8)
    parking--;

  if(duration7 < 8)
    parking--;

  if(duration8 < 8)
    parking--;

  Serial.print("number of empty Spaces: ";
  Serial.print(parking);
  Serial.print("\n";



  delay(100);



}

long microsecondsToInches(long microseconds)
{
  // According to Parallax's datasheet for the PING))), there are
  // 73.746 microseconds per inch (i.e. sound travels at 1130 feet per
  // second).  This gives the distance travelled by the ping, outbound
  // and return, so we divide by 2 to get the distance of the obstacle.
  // See: http://www.parallax.com/dl/docs/prod/acc/28015-PING-v1.3.pdf
  return microseconds / 74 / 2;
}

long microsecondsToCentimeters(long microseconds)
{
  // The speed of sound is 340 m/s or 29 microseconds per centimeter.
  // The ping travels out and back, so to find the distance of the
  // object we take half of the distance travelled.
  return microseconds / 29 / 2;
}



和一个LED Display，我要怎样把Arduino收到的Information，寄出Serial Command去LED？

Supplier说：把"B101"放进去就行了...
