  • I created an LED that can use switch to turn ON/OFF and use the photo resistor to change its lightness, as demonstrated in the video. The lightness of the LED does not change so drastically, maybe because of the photo resistor is having trouble accurately detect the light, or I maybe because I mapped the lightness not so well. It's strange no matter how I change the mapping function, the lightness of LED does not change so much, though.
