Sound Sensor coverage on Lego Education blog
Lego Education NXT has posted a closeup picture and some information on the sound sensor... read it here.
Some thoughts: I mentioned in an earlier post how the tone sensitivity could be used to control the bot by using the sounds from a guitar or a touch tone phone (it if's loud enough or if the sensor is sensitive enough). I like that it can distinguish between two voices... I imagine they must be dissimilar in certain ways (my brother and I sound alike, so it wouldn't work for us).
Only the Ultrasonic Sensor is left to cover (unless maybe the HiTechnic sensors will get some coverage here). Thanks go to Lego Education NXT for providing pictures and information on the sensors, motors, and other items...
