I have been scouring the internet for a simple example that I can expand upon and have had no luck and am hoping someone can help. I want to control an Arduino through an Ethernet cable using VB code on a PC. I have found where someone does this but uses a WiFi connection but I have not been able to successfully modify the code to get it to talk Ethernet instead of WiFi. I will attach the code I have so far but it may be easier if someone knows of a simple example to say turn on a single LED using the above I can modify the example to get what I want.

The attached code does talk to my Arduino because I can see the TX and RX lights blink when I click on the form button but I cannot get the LED to turn on or off. Arduino code. You're going to have to decide whether you want to use a web server / HTTP approach or an old-school telnet-style approach on the Arduino. There are plenty of examples for the web server case (and in fact Zoomkat will be here any second to share some solid working HTTP code.) It might be worth taking a look at the BitlashWebServer example that ships with Bitlash (It's a sketch that exposes Bitlash scripting as a web service from the Arduino over Ethernet. It also has a telnet server so you can just send commands, as opposed to commands wrapped in HTTP GET requests. For your project you could just send 'd13=1' to turn on the LED on pin 13, and 'd13=0' to turn it off.

Bitlash here: and you can browse the web server/telnet sketch code that ships in the distribution here: Good luck with your project, -br Edit: D13 is not going to work for an LED because it is used by the Ethernet shield. Discovered this while creating a new built-in script for the BitlashWebServer. But now you can open a browser on the server ip-address/toggle5 and it will turn pin 5 on and off. I haven't had much of a chance to play around with any of the code yet but I can answer some questions. I have tried the HTML version of control and I did get that to work with my Arduino. I guess one thing I am wondering here though is how can I implement a momentary button action while using Ethernet communications.

From the small amount of web experience that I do have I believe a webpage is more like an on/off switch. Is that correct? I am assuming I could probably build in some kind of delay but it would get old having to click the button many times to keep something like a light on. I do not have much experience with an Arduino so far and am trying to learn more everyday. I will attempt to work on the ideas mentioned above this weekend but if anyone has ideas of how I can implement a momentary style switch instead of an on/off switch it would be greatly appreciated if you would share your thoughts or ideas. Thank you everyone for your help and posts.

I have finally got it working!! PaulS, thank you for your initial post. I took a better look at my code and compared it closer to a working version of the HTML working code and found that, as you said, I was never reading the client. As for other ways of doing the same thing I am wanting a momentary button so that on my PC I would click a button and while I am holding the mouse button down the light would be on and once I let go the light goes off until I click and hold the button again.

I have implemented this using the keyboard but thought it would also be nice to do it in VB code as well using the mouse but haven't figured it out just yet. Also thank you to rbright for the link. I can definitely see some uses for that interface and program in the very near future. My working code is below. It has some extra items in it that I got from another example but I think I can modify it to make what I want. Arduino Code.

How to: Receive Strings From Serial Ports in Visual Basic. 2 minutes to read. Contributors. In this article This topic describes how to use My.Computer.Ports to receive strings from the computer's serial ports in Visual Basic. To receive strings from the serial port. Initialize the return string. Dim returnStr As String = '.

Determine which serial port should provide the strings. This example assumes it is COM1. Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see. The Try.Catch.Finally block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block.

Dim com1 As IO.Ports.SerialPort = Nothing Try com1 = My.Computer.Ports.OpenSerialPort('COM1') com1.ReadTimeout = 10000 Catch ex As TimeoutException returnStr = 'Error: Serial Port read timed out.' Finally If com1 IsNot Nothing Then com1.Close End Try. Create a Do loop for reading lines of text until no more lines are available.

Do Loop. Use the method to read the next available line of text from the serial port. Dim Incoming As String = com1.ReadLine. Use an If statement to determine if the method returns Nothing (which means no more text is available). If it does return Nothing, exit the Do loop. If Incoming Is Nothing Then Exit Do End If.

Add an Else block to the If statement to handle the case if the string is actually read. The block appends the string from the serial port to the return string.

Else returnStr &= Incoming & vbCrLf. Return the string. Return returnStr Example Function ReceiveSerialData As String ' Receive strings from a serial port. Dim returnStr As String = ' Dim com1 As IO.Ports.SerialPort = Nothing Try com1 = My.Computer.Ports.OpenSerialPort('COM1') com1.ReadTimeout = 10000 Do Dim Incoming As String = com1.ReadLine If Incoming Is Nothing Then Exit Do Else returnStr &= Incoming & vbCrLf End If Loop Catch ex As TimeoutException returnStr = 'Error: Serial Port read timed out.' Finally If com1 IsNot Nothing Then com1.Close End Try Return returnStr End Function This code example is also available as an IntelliSense code snippet. In the code snippet picker, it is located in Connectivity and Networking.

For more information, see. Compiling the Code This example assumes the computer is using COM1.

Robust Programming This example assumes the computer is using COM1. For more flexibility, the code should allow the user to select the desired serial port from a list of available ports. For more information, see.

This example uses a Try.Catch.Finally block to make sure that the application closes the port and to catch any timeout exceptions. For more information, see. See Also Feedback.
