The holy grail of the BEEP(1400, 0.08) command: USB-HID

[Giancarlo]

Hello and thank you very much for the long explanation.
That makes me feel really unprepared to deal with such technology without clear indications :+)

I understand that depending on the sensor or actuator we should need an external power source or not.

Regarding the speaker, do you think I would need an extra source? I don’t have to play songs, just few beeps. I used to do some time tracking with my calculator and create project reports based on time spent.

Thanks

Giancarlo
