#include <SoftwareSerial.h>
SoftwareSerial BTSerial(10, 11); // RX | TX
char status = NULL;
void setup()
{
pinMode(13, OUTPUT);
BTSerial.begin(38400);
}
void loop()
{
if (BTSerial.available())
//從藍芽接收Client傳送的字元
status = (char)BTSerial.read();
//H為開F為關
if (status == 'H')
digitalWrite(13, HIGH);
else if (status == 'F')
digitalWrite(13, LOW);
}
C#.Net程式碼如下：
using System;
using System.IO.Ports;
using System.Windows.Forms;
namespace SendDataForBluetooth
{
public partial class Form1 : Form
{
/// <summary>
/// SerialPort
/// </summary>
private SerialPort _serialPort;
public Form1()
{
InitializeComponent();
this._serialPort = new SerialPort("COM16", 9600, Parity.None, 8, StopBits.One)
{
ReadTimeout = 10000,
WriteTimeout = 10000
};
this._serialPort.Open();
}
/// <summary>
/// 關燈按鈕
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
On();
}
/// <summary>
/// 開燈按鈕
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
Off();
}
/// <summary>
/// 視窗關閉時關燈
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
Off();
this._serialPort.Close();
}
/// <summary>
/// 開燈
/// </summary>
private void On()
{
if (_serialPort.IsOpen)
_serialPort.Write("H");
}
/// <summary>
/// 關燈
/// </summary>
private void Off()
{
if (_serialPort.IsOpen)
_serialPort.Write("F");
}
}
}
執行結果：
開燈前
