Dog Bowl Monitor

I found a empty Cetaphil cream case, so I was going to make bathroom monitor.During making it, I was watching animal channel.  I got an Idea making a device checking Dog bowl, even though I don’t have a dog or cat.  If there is food, it lights blue. No food is with red light.

I use the last class code. just added one more LED
