Visual Basic Code: Private Sub TimerSerial_Tick(sender As Object, e As EventArgs) Handles TimerSerial.Tickĭim bytesToRead As Integer = SerialPort1.BytesToReadĭim bytesRead As Integer = SerialPort1.Read(bytes, 0, 12) A quick guide to getting started with the Visual Micro Arduino Extension for Visual Studio, from project creation to IDE Layout. The whole reason for Buffer is that when I update the values with it (from VB to Arduino), the changes on the graphs of VB are so slow that I wanted to use buffers Furthermore, the "last_input" in the arduino is the value that I give from visual basic. When I open the byte packet on visual basic I get garbage values. I sent values from arduino to visual basic as byte packets and wanted to read these values inside visual basic and apply them to graphs. I have developed a serial communication through port between arduino uno and visual basic (.net framework).
