My robotics class recently got a whole bunch of those BOE-Bot Speech Boards, and they work REALLY well the first time we used them. But ever since then, it gets words mixed up all over the place. It is currently saying 'zero' instead of 'Object detected, turning left.' Just as a test, we used one of the other speech boards, and again, it only works the first time... I am just wondering, what am I doing wrong? I am using the default Talking IR code that came with it. If you could help, that would be great... thanks.
