[LUCA_ARMANI_GAUSS]

Hi all, thank you in advance for your answer, as in the title, can you explain me how to receive data from OLA board because I want to use this data with an arduino UNO. I tried to connect Tx to Rx and vice-versa using the same boudrate but nothing goes into arduino, I also turned on in the menu of OLA the "Output serial data to TX pin".

re-review config option #14 here and ensure you have the correct setting enabled, then also compare/change the baud rate on either side to make sure it matches too

Also note that if using the analog pins https://learn.sparkfun.com/tutorials/op ... e-overview (12 & 13) they are 2v

Thank you for your answer, I checked option 14 and baud rate, they are correct. Do I need to analogRead in Arduino? And not just use serial read?

[TS-Russell]

I was saying that if you are using analog inputs note that they are saturated at or above 2v

Can you test another device with the arduino to ensure it is working, and/or vice-versa? (use another MCU + OLA)

Did you connect the grounds as well?
