possible to have it be compatible with vb 6.0 and newer?
i really haven't tried my hand at C or C++... but i do know vb 6.0. is there a way to incorporate this?
Well vb 6.0 is a programming application (A IDE) that runs on a windows PC, so it doesn't have any 'compatibility' with how one programs an arduino board. However if you wish for a arduino sketch running on a arduino board to be able to send or receive data to a program written in VB and running on a PC, then yes they are 'compatible' to the sense that they both can send and receive data via a comm port based serial communications to each other. Is that what you are asking about?
