Hi ; First of all congratulations for your gret video.Can you please be so kind and let me know the name correspondenr Arduino sketch I imagine is in your Dropbox..Thanks a lot Regards Domingos

i literally copied the code word by word and the math is not right, the lcd is printing a huge number when its dark and prints a small number when its bright, the same thing happens in his lcd screen, but is hard to see because he has the screen not so visible with a reflection. Also, you can make variables a lot shorter, just saying.

Hi, my light level is showing "inf" as well as other numbers. Any idea what could be causing this? I have followed the code on your tutorial.

+duduken103 If it's showing inf Inuit could be your voltage divider is not wired correctly.

[@duduken103]

Thank you! That seemed to be the issue. Also, what's the value of the carbon resistor you are using?
