Control arduino pins with vb.net

e14 Contributor

I am using vb to control arduino which in turn is switching a relay to control higher voltage and current.

I can send 0 thru 9 and arduino reads it and performs a function.

The problem is when i try to send , for example , 11 . The arduino sees a 1 and functions the "1" command.

How can i get arduino to recieve an "11" ?

    My suggestion is to make all the commands a 2 digit.

    For a 1-9 send 01 - 09.

     

    The other option is to look for the CR/LF charcters as part of the sent string.

     

    Since you are using VB in between the keyboard and sending, and then using the Arduino to intercept and process them, you have multiple options to constuct a mesage protocol.
