Brick Labs

This example takes the project from Example 2, and replaces the potentiometer with a sound sensor from LEGO.

Here is the project (same exact one from the prior example).

And here is the robot with the attached sound sensor.  Please note… I’ve only put the sound sensor in this location since the robot isn’t actually driving.  If it was going to be driving, I’d probably not bother with the sound sensor.  They are notorious for picking up the sound of the motors.

This time, everything worked perfect.  The LEDs almost pulse in time to your speaking, which is a neat effect.

My son came in to see what was going on.  He near broke my eardrum trying to get a nice loud noise to spike the LEDs.  Loud claps less than 6 inches from your ear tend to hurt.

This project was a very simple one.  I didn’t have to do any debugging or tweaking, since it just worked.

Example 5 deals with a home-made light sensor.  Should be a good project for tomorrow.
