however, how to implement simulink under arduino IO package with arduino board.. if i running the simple block, the message will be like this
Connection unsuccessful, please make sure that the Arduino is powered on, running either srv.pde, adiosrv.pde or mororsrv.pde, and that the board is connected to the indicated serial port. You might also try to unplug and re-plug the USB cable before attempting a reconnection.
