NXT version of the LEGO Mindstorms robots have a sound sensor. It can detect ... sound. You can make the robot do things when you clap, move, or just when you are silent.
In this episode of the Basic NXT Programming series I will cover the sound sensor. I will explain how to program the sound sensor, stop on common problems faced, when the sound sensor is used and finally we will build a program that will allow us to control the robot's speed through the volume of the sound.
During the FIRST LEGO League competition you can hardly use the sound block, because of the noise from the excitement around the tables, but it has a few interesting applications. I this video lesson I will show you how to use the sound block and build a program that makes the robot say which color it sees.
