Concept
The unusual switch I decided to create is not as unusual as I anticipated. I just decided to create something out of that awkward experience when your roommate turns on the light in the middle of the night. I used the arduino to power an LED connected to a photo resistor. The photo resistor produces less resistance and it is exposed to more intense light.
Ideas for Future Improvement
I believe it would have been more fun with some form of text display or a buzzing sound, but hearing a buzzing sound in the middle of night isn’t a good idea (smiling emoji).
