I've been trying to program my arduino to communicate with Max/MSP/Jitter. I'm very new to this. I've downloaded the arduino software. And I've been using Simple Message Systems instead of Maxuino (I've been told that its easier). I've compiled the code and uploaded it to my board. I can see that it is communicating with Max because the lights on the board blink when I turn on the toggle in the SimpleMessageSystem.mxb. However, when I set up my own max patch (built out of the Simple Message patch) and hook up a switch to my board the commands won't go through. I feel like I've double checked everything, but is there something I've missed?
