In testing for over a year or so (since 13 Aug 2015) -- all features work as advertised and as such, it is recommended to run this instead of the v1.0 build.
Items of note:
- Button push detection is instant, as well as heat level indication as buttons are pressed.
- Blink is now non-blocking -- will power off device before pushing pulsing state.
- Heat level (saving) is seat independent -- same applies to auto start.
Binary files attached were built for an Arduino Nano (ATMega 328) using Arduino 1.6.12.
