I am having the same problem. How were you able to resolve?
Here's how I got it,
I was surfing the web after posting this and someone on youtube was in depth about this certain project.
The light sensitivity is the issue.http://rookieelectronics.com/light-sensor-using-arduino/
Copy and paste the code, then follow the video and when he mentions light sensitivity play close attention to that part with the monitor and set it by the lighting in your room, so if it's at 460 put it below that.
