Lighting box

Due to the power problem with Arduino board, I have to choose the nearby computer which can use Arduino program to set up my installation. The sensor which sense the paper and LED inside the white box both work well. However, the LED was not bright enough to turn the white box into green when it stays under normal light.


I turned off half light in the lab at night...then it looks much better. So that I try to add more LED into my Arduino sketch to achieve this result even under the normal light. If it is bright enough, it will attract the eyes of people. Then I want to paste some character label onto the sides of the box to persuade people "think before print".

Think before you print:the box with label and 4 LED lighting.
