Nice project.

As someone who gets second degree sunburn in about 20 minutes, I may have to duplicate your design and code for my own use.

Hey Gene, I have been thinking about how to shrink this down and run it from a tiny battery. So the main "feature" to add would be power management. Obviously calibration is important too.

Nice project! I like the idea behind monitoring for UV exposure. It will be interesting to see how you polish this up into a full feature device.

Andy, how did you calculate the integral? A math library? Python?

It's interesting watching that back how much delay there in the analogWrite. The red LED goes off and there's a noticable delay before the green goes back on even though it's just the next line of code.
