[pilot205]

Hello,
is it possible to connect audio buzzer?

Thanks.

@pilot205 I'm new here and I'm also researching sound.
ideals:

I recently bought a Lilygo T-echo with bme280.
I would like to know if there is a possibility to update.
using it for paragliding flight.

put a sound (buzzer) to use in the variometer function!
example https://www.youtube.com/watch?v=ehkRXz7TV8k
when going up it makes noise, when going down it usually sounds < -2m/s

also add an ascent and descent indication screen!
with this example

be able to adjust the program

I did it

I couldn't add it to the t-echo so I did it separately
up sound always on, down sound only < -2m/s

The idea was to be able to put a sound on the lilygo t-echo, after trying to get the programming code and not being successful (open source, but I couldn't find it). I decided to make a separate arduino (I know it could be solved by adding the buzzer to the t-echo, but without the program it is unfeasible). arduino variometer project that has on the internet! The idea is to use t-echo on the Kobo Touch with XCsoar, as the kobo doesn't have sound the way I got it was this! Now I just have to learn how to put a bluetooth module on the kobo, how to pair the hc05 with the t-echo (if anyone knows or can give me a tip, I'd be grateful) imagine getting sound and another screen like that on the lilygo t-echo would be the dream https://www.youtube.com/shorts/B1Fd2gZ12Ms
