I have a complaint: The images on your site are blocked. You need to loosen the security.
Sorry, I didn't notice the problem. It is fixed now. Thank you!
And two suggestions...
1. (Optionally) Output the result to Serial. I can imagine the device being connected to a computer to generate passwords (or maybe even dice rolls).
I will take care of this. It is funny, I actually removed the code that did this since I was only using it for testing purposes!
2. Add a coin flip option.
Duh, I can't believe that this one didn't even occur to me!
