Hi members, yes, I was quite busy the past days creating projects.
This is a combination of the two recent projects: "M5Dial Timezones" and "M5AtomEcho ATOMECHOSPKR class to play simple beeps". In this combination the M5Dial sends a digital impulse (read: beep command), on pin 1 of its Grove Port B. The beep command is sent at the moment of a NTP Time Synchronization. In this moment a "TS" occurs every 15 minutes. The sketch running on the M5Atom Echo device is "listening" on its Grove Port pin 1 for a digital impulse. If such a "beep command" is received, or when the button on top of the M5Atom Echo is pressed, the Atom Echo will produce a double tone beep. At the same time the builtin RGB Led of the Atom Echo will first show Green and after the beeps have finished, the RGB Led will turn RED (again). See: repo.
