Multiple Serial test
|
|
|
|
Receives from the main serial port, sends to the others.
|
|
Receives from serial port 1, sends to the main serial (Serial 0).
|
|
|
|
This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc
|
|
|
|
The circuit:
|
|
- Any serial device attached to Serial port 1
|
|
- Serial monitor open on Serial port 0:
