Hello World! video
I made a short video showing basic functionality. No sound in video but there is piezo beeping when alarm is triggered on. Timing is customized for better demonstration. Don’t turn of annotations to see more info.
First tap on idle panel activates given button group. Consequent taps are interpreted as commands. Alarm settings are backed up in EEPROM after each change. You can snooze alarm as many times as you want. Timeout for LED lights is indicated by very short blink in addition to visual indicator.
(I found that large LCD font on Seetron site. Hoping they do not mind using it in personal, non-commercial project.)
