Can anyone teach me how to collect data with the Arduino Uno Board using the COM in Visual Basic?
I am try to use the snippet in VB,but the program never load properly or maybe the code itself is wrong.
I am quiet new with all the programming,so please teach me step by step.
//VISUAL BASIC IN WINDOWS NOT ARDUINO

CODE: SELECT_ALL_CODE

 Dim buffer As New StringBuilder()
        Using comPort As SerialPort = My.Computer.Ports.OpenSerialPort("COM3")
            Do
                Dim line As String = comPort.ReadLine()
                If line Is Nothing Then
                    Exit Do
                Else
                    buffer.AppendLine(line)
                End If
            Loop
        End Using


My Arduino connect at COM3 using USB.
What am I trying to do is collect all the data and save it/convert the data to something manageable for graph in Spreadsheet.Anyone can help?
OR
I have the wrong Arduino Board?I thought Arduino Leonardo is suitable for data storage and ArduinoMega is for Android Phone.
Which one?!Whatever...

im not so sure whether u can send data from the arduino board through the usb to the computer.
u can try send simple characters in a forever loop from the arduino board, then open the terminal to view if characters are received. remember to set the correct COM and baudrate.

Thanks for reply,yes,you talking about the Arduino IDE,right(from the Serial Monitor-I hate copy & paste)?I have link to the problem.I think I am answering my question.

erm, are u going to connect the android device to your arduino board through bluetooth?

I don't really understand this thread? You talk about VB, sending data through Serialport. You want make oscilloscope, then talk about android. I don't know which one your focus.
If VB SerialPort see here.
If VB graph see here.

1) Not Bluetooth.Just USB.
2) All of it.VB,C++,C# and Android.

yr android device has the usb host?

no &no idea.thanks.just stick with the topic.just for discussion.i am a new learner in arduino.

Thanks.
