Bob, What other code are you running? What does your motor code look like? Does anything get hot when this happens, like the motor control chip, the hex inverter or the voltage regulator? Gary Livick (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

Hi Sonny, I've played with Voice Direct and also with the HM2007 chip. Both of them work fine in a quiet environment, but in my limited playing they were both overwhelmed by the ambient noise of a moving robot. They both are speaker dependent, and (...)
