For a more complex project I would enclose all data in markers as an easy way to ensure I receive a complete command.ĭepending on the button / slider used, the VB program sends different commands to the Arduino. In this example there is very little data sent from the Arduino to the host computer and so I have not used start and end markers for the data send from the Arduino. The data sent to the Arduino is formatted in to commands which are enclosed in start and end markers "". The communication between the Arduino and Visual Basic is done using ascii over serial/usb. Basically the same circuit as used in the Bluetooth project minus the Bluetooth module. Here is the app screen.Visually it is nothing special and all controls are straight out of VB but is it working well. So all I need do is tweek the Arduino sketch and recreate the Android app in VB. I already have a similar project arduinoBTcontrol, where the Arduino is controlled from an Android app over Bluetooth. The next step is two way communication and controlling the Arduino from the VB program. My first attempt resulted in a very basic app to receive data from the Arduino which taught me the basics of serial communication in VB.
I am still very new to Visual Basic and I have been surprised at how quickly you can develop working apps.
