We have a potential client asking about creating a small device that can accept commands via bluetooth and act on them by lighting an LED or vibrating. Does anybody have any recommendations/advice.
I would do that with an esp32 dev board instead of a Pi which is overkill for this application, except there are lots of other things to implement ?
agree, pi is a device with operation system,
arduino boards just run a small app.

There is ways to control it via terminal (e.g. shell class).

Hi Tim,
Your customer is likely to add more feature requests. An arduino may be harder to deal with, but the RPi will work with unforeseen new features.

how small ? can it be a raspberry pi zero 2w ?
does it need to bluetooth?
