S100 - The Arduino Starter Kit - Project 04

For this project, I was introduced to the PWM (pulse with modulation) technique, duty cycles, and photoresistor sensors.

The green photoresistor never seemed to be working... so I tried a few different photoresistors for this particular gel... but, still got the same results. I really like the fading that is being created by the amount of light visible to the sensor... I wonder if this would be a good way to change color in the compact mirror project...
