Controlling servo with PC using Visual Basic and PICAXE 08M
October 1, 2011
i am attempting to control a servo by clicking a button on my PC. From what i understand i have to use Visual Basic. i have not used VB before and dont really understand it. i noticed this instructable http://www.instructables.com/id/Control-real-world-devices-with-your-PC/ and have tried to build the circuit many times but it just isnt working. when i open the VB program and try to connect to the PICAXE it comes up with "A first chance exception of type 'System.IO.IOException' occurred in System.dll" and a timeout occurs. any help would be appreciated. and i also have a PICAXE 20X2 if it would be any easier with that chip.
i posted a pic of the error that occurs.down the bottom left hand corner you can see the error and in the foreground form pop up it says timeout.
