New Toy

So, my students are taking their TNReady tests and I've had a little spare time this past week. What does one do with spare time? Create electronics, of course.... This week, I put together a noise level indicator for the classroom using some LED's, a breadboard, a microphone, and an Arduino Uno. I've actually improved on the design in the video and I may upload a new video with the new and improved version. Let me know what you think!
