Science Buddies: "Ask an Expert"

Last year I completed my science project on the infinity mirror using LED color changing lights. I created multiple mirrors and graphed number of reflections. I loved this project and want to use the same concept this year, but have it more complicated or advance in nature. Do you have any suggestions? Please help me. I researched all over the internet and couldn't come up with any variation or advancement to this. I already have all the materials saved from last year.

Hi nancy2323,

Did you work on the Arduino-controlled mirror project described at the following link?

If so, you might consider adding some programmed features to the light display. For example, you might add a temperature sensor to the circuit and program the system to change the light color as the temperature changes. Or you might add a motion sensor and programming that switches the lights off when someone approaches so that the system can be temporarily used as a regular mirror. Or you might add programming that randomly changes the light color.

I hope this helps. Please ask again if you have more questions.
