PA Designer : Project

The GoPiGo3 comes with sensor mounts that allow you to attach your LED to the chassis. However, let’s have some fun with this. Why not make your LED look like a lamp using Lego Technic or whatever craft materials you have to hand? To give you some ideas, here’s an example that we made:

Using a sensor mount and the mounting holes in the chassis, mount the loudness sensor upright on the top of our robot. 

Using whatever craft materials you have to hand or even Lego let’s make a directional sound chamber to shield the sensor from sound from behind and focus it more on the sound in front of it. This will make it easier to hear the doorbell in a noisy environment.

Test the effectiveness of your chamber. Re-run the 10 second data analysis task from the LEARN section a number of times, with and without the chamber, to compare the effect of ringing the bell immediately in front of and behind the sensor. 

Try out different materials to see which ones work most effectively for you. What materials give you the best soundproofing from behind? What do you think makes these materials good for soundproofing?

Now it’s time to code up your robot assistant.

Using what you have learned, change the code in the Main Code cell so that your robot listens intently for a bell and when it hears that bell it stops listening and switches on the light.
