Romeo sound
ViennaMike 2011-11-08 10:52:41 4100 Views3 Replies I got a Romeo almost a year ago and finally got the time to start working with it. When trying the sample code to move the robot, I got a tiny amount of movement and longer tones. I'll keep looking at what I'm doing, but does this mean there's a speaker on the board? Why am I hearing a tone, and can the user control/program it?

tone that really doesn't sound like a motor. I don't get that running some other examples,
just a motor noise like I'd expect. But that's fine. ViennaMike

If you are using the yellow DC motors, they make a some noise when operated. There is no spkr on the Romeo, there should be no sound coming from the Romeo
