Hi I am trying to build serial connect between two arduino baords with radio connection.
The recipient module gets values from 0V to 0,8 V. So I boosted up the signal that 0V stays 0V (digital 0) and everything grater than 0,6 becomes ~ 5V (digital 1).
Is it correct that the serial input (RX) accepts ~0V als logigal 0 and ~5V als 1??
Thanks for your help!
