Hi, guys. I need your help.I want to listen Serial ports by using Arduino. I have 6 Serial Channels and I need to listen these channel and be sure which channel is working. How can I do that? Can I listen this channel by using digital inputs? If I can do that Arduino uno or nano is adequate for my project.
Or Do I have to use a devices which has a 6 Serial ports? Like 2 Arduino Mega?
