Introduction: Getting Started With Arduino and Visual Basic 2008
Making of Gui is always one of the interesting and enjoyable thing in controlling system. in this instructable we are going to learn making of Gui with visual basic 2008 and arduino .So here we start With Led
Part to be Required
1.LED
2.220 ohm Resistor
3.Arduino board
Step 1: Bread Board Circuit
Arduino Program
int led= 2;
void setup() {
Serial.begin(9600);
pinMode(led, OUTPUT);
}
void loop() {
if (Serial.available())
{
int Blinkdata = Serial.read();
if (Blinkdata=='a')
{
digitalWrite(led,HIGH);
}
else if(Blinkdata=='b')
{
digitalWrite(led,LOW);
}}
}
Step 2: Making of Visual Basic Form
Make Form as Shown in Image with the help of
2 buttons,
Label,
2 Combo box,
1 Serial Port
Step 3: Visual Basic 2008 Source Code
Define IO Libraries
Imports System.IO
Imports System
Imports System.ComponentModel
Imports System.Threading
Imports System.IO.Ports
Public Class Form1
Dim myPort As Array
Shared _continue As Boolean

Application.Exit()
End Sub
Connect Button
Private Sub Connect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Connect.Click
SerialPort1.PortName = ComboBox1.Text
SerialPort1.BaudRate = ComboBox2.Text
SerialPort1.Parity = IO.Ports.Parity.None
SerialPort1.StopBits = IO.Ports.StopBits.One
SerialPort1.DataBits = 8
SerialPort1.Open()
Button2.Enabled = True
Button3.Enabled = True
End Sub
Disconnect Button
Private Sub Disconnect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Disconnect.Click
SerialPort1.Close()
Button2.Enabled = False
Button3.Enabled = False
End Sub
Commport Combo box
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If SerialPort1.IsOpen = False Then
SerialPort1.PortName = ComboBox1.Text
Else
MsgBox("You cant change comm Port While its open!", vbCritical)
End If
End Sub
Baudrate Combo box
Private Sub ComboBox2_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox2.SelectedIndexChanged
If SerialPort1.IsOpen = False Then
SerialPort1.BaudRate = ComboBox2.Text
Else
MsgBox("You cant change comm Port While its open!", vbCritical)
End If
End Sub
Form Load
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Button2.Enabled = False
Button3.Enabled = False
'Partial Load
myPort = IO.Ports.SerialPort.GetPortNames()
ComboBox2.Items.Add(9600)
ComboBox2.Items.Add(38400)
For i = 0 To UBound(myPort)
ComboBox1.Items.Add(myPort(i))
Next
End Sub
LED on
Private Sub ON_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
SerialPort1.Write("a")
End Sub
LED OFF
Private Sub OFF_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
SerialPort1.Write("b")
End Sub
End Class
