This one went pretty well with only one minor snag. The second button wasn’t correctly turning off the LED. I discovered that I’d bent back one of the pins underneath the button when installing it and it wasn’t correctly connecting to the circuit. Everything worked nicely once I properly reattached the button.  I also noticed that pressing the buttons quickly tended to cause the press not to register.  Something to keep an eye out for in the future.
