Physical computing midterm project : Mirror, Mirror

Kenzo Nakamura and Tiri Kananuruk

We came up with idea of making switch for the light by clapping because we are lazy to get up and walk to switch. We decide to use Microphone Sound Detector for a sensor to catch the sound and send analog signal to the light.

first prototype used a real lamp. so we have to use relay to power up the voltage. It works! but it can’t dimming the light. The problem is the power switch tail can’t dimming the light.(because it convert DC to AC) So we have to change from light bulb to Neopixel LED

and IT BROUGHT US A LOT OF PROBLEM!!!! hahahaha oh gosh!!!!
okay first, we have to change all the code. Neopixel need their own library.

Finally our code works!! here is the final arduino code!
With helps from these people!

Kenzo did a great job on P5 sketch! he made a Serial Input to P5! and made a cool interface

and yes Here is the final video!!
