this instructable is part of my book Arduino + visual basic 6.0 (make your own software to control arduino Robot.

Visual basic 6.0 is a very old version some people may ask why we want to use visual basic 6.0 . visual basic 6.0 is a user friendly programming language ... so if you are beginner and want to lean basic pc based controlling system then visual basic 6.0 is a best option for you ....here we start :)

part to be required

1.Arduino board

2.bread board

3.jumper wires

4.leds

software's

1. visual basic 6.0

2. Arduino ide

Step 1: Bread Board Circuits

Here we use Pin 9 as digital output pin connect Led With 9 Number pin of Arduino Board .As shown in breadboard circuit .

Step 2: Arduino Program

int led= 9;

void setup() {

Serial.begin(9600);

pinMode(led, OUTPUT);

}

void loop() {

if (Serial.available())

{

int drukdata = Serial.read();

if (drukdata=='a')

{

digitalWrite(led,HIGH);

}

else if(drukdata=='b')

{

digitalWrite(led,LOW);

}}

}

Step 3: Visual Basic 6.0 Program

make form shown in picture

Program for Visual basic 6 (Led on off Control Software)

Private Sub EXIT_Click()

Form1.Hide

End Sub

Private Sub Form_Load()

MSComm1.RThreshold = 3

MSComm1.Settings = "9600,n,8,1"

MSComm1.CommPort = 2 // (Write Port Number on which your Arduino Board is available).

MSComm1.PortOpen = True

MSComm1.DTREnable = False

Text1.Text = ""

Shape1.FillColor = vbRed

End Sub

Private Sub TURNOFF_Click()

MSComm1.Output = "b"

Text1.Text = "LED IS OFF"

Shape1.FillColor = vbRed

End Sub

Private Sub TURNON_Click()

MSComm1.Output = "a"

Text1.Text = "LED IS ON"

Shape1.FillColor = vbGreen

End Sub
