(as seen below) This involves sending a byte to each of the COM ports and checking the response, in your Arduino sketch you can set it to respond to a certain string – If it matches this in VB.NET when you read the COM port then you have the right connection. You can either place this list of COM ports in a ListBox, or even better, configure your project to ‘auto’ connect to a COM port. Now that you have a basic application to work with, take a look at the following piece of code: For Each p As String In My.Īs you can see, you can get a list of available COM ports on the system, this is useful as the user does not have to select the correct COM port. We have named ours COMTest and saved it to the Desktop folder.
We are using Visual Studio 2015 for this tutorial, load it up and create a new project. You can easily and quickly use VB.NET to send and receive information from the serial COM port that your Arduino uses. One of the main features you can add to your Arduino, is communicating with it via an application.
